Migrating from a 32 bit architecture to a 64 bit architecture for BOE XI 31

We have (OS) Windows 2003 server, on two servers clustered together running BOE XI 3.1. Are there any known issues or encountered issues with migrating from 32 bit architecture to 64 bit architecture?

The 32-bit versions of BOE will run on a 64-bit operating system provided that you use the same bit version of middleware. Since there is no upgrade path from 32-bit O/S to 64-bit O/S, you will be performing a new installation on the 64-bit servers. As usual, ensure that you back up your repositories, BOE dbs, and custom configs prior to the rebulid.

Migration from Windows(32 bit) Oracle 9i db to Linux(X86-64 bit) Oracle 10g

Hi,
We are planing to Migrate our Oracle 9.2.0.6 version database from Windows(32 bit) to Oracle 10.2.0.1 version database on Linux(64 bit). Can I directly do the Migration using export/import? or What is the procedure to do this?
Thanks in advance for any help.

The directory structure is different...that's why you need to create the tablespaces in Linux. e.g. export dump says create tablespace in D:\..., there is no such thing in Linux. You can just export it, install software, create the db, tablespaces in Linux and import into the 10g in Linux.

Migration from Oes2 32 bit to Oes11 64

Realized my groupwise mta/gwia/webaccess is running on a 32bit Oes2 machine. Obviously cant "upgrade" that to Oes11.. so creating a new pre-migration server for it.
Straight forward? Plan on using the Transfer ID wizard to accomplish this. but then expect I need to re-install groupwise modules after. Do I need to use the groupwise migration utility as well?

Hi Joe,
We're in the process of doing the above (among other things)
You have two choices:
OES2 SP3 -> OES11/SP1 migration
or
the above, but WITH ID Transfer.
It's entirely up to you if you want to keep the same servername/IP.
We chose the ID transfer.
Groupwise is VERY straight forward to go from linux to linux, IMO
However:
While we have had issues using the Novell Client for Linux (included in OES11) to migrate (via dbcopy), we have NOT had issues using the ncpmount with dbcopy. However, other people have had issues OES2 -> OES11 with ncpcmount.
There were some other intracacies with the ID transfer when going from OES2 to OES11 that I'm in the process of documenting:
a) DHCP/DNS objects/migrations are a bit odd because you'll end up with a DHCP object with the "temporary" servername of the OES11 server.
b) You'll end up with the temporary server name of the OES11 server for the OESCommonPRoxy user if you're using it. I'm currently talking to the developers to discuss a way to fix/resolve that.
However, if all you have is an OES2 server that JUST runs Gwise, then it's fairly straightforward. No need to change the case since it was already done. You'll just have to remember to copy over your .poa/.mta and any other startup files and reinstall the GW agents AFTER the ID Transfer.
I'm paraphrasing here, of course.
I'm parially through scrubbing my OES11 SP1 migration guide for incriminating IP's, etc. so hopefully I"ll have something on cool solutions next week.

EBS R12 Migration from Linux 32 bit OS to 64 bit

Hi all,
Curently we running EBS R12 in linux 32 bit server. We are planning to migrate the same to a Linux 64bit OS. Both Apps and DB are running in one Server.
Current version : in Server XXXX
EBS - 12.1.3
DB - 10.2.05
OS - RHEL AS 4.5 32 bit
New Version will be : in Server YYYY
EBS - 12.1.3
DB - 10.2.0.5
OS - RHEL 5.5 64 bit
Please guide me with a good and easy steps.
Thanks,

Hi;
1- Installl Redhat Enterprose Linux 5 64 bit ( need to confirm the 5.x version ) as the current DB 10.2.0.5 will not certified for RHEL6Correct only 11.2.0.3 db version is certified with RHEL6.
In oracle certification I can see the certified 64 bit RHEL OS for 10.2.0.5 is RHEL5 ("Oracle Database 10.2.0.5.0 is certified on Linux x86-64 Red Hat Enterprise Linux 5"). Please let me know the last supported version in RHEL5 which I can go for. I could not find anything about it. I am thinking, I can go for RHEL 5.5 and in the same OS can I upgrade DB 10.2.0.5 to version 11.2.0.3 after the migration.?The latest version is 5.8 and you can download it from e-delivery.
PS:Please dont forget to change thread status to answered if it possible when u belive your thread has been answered, it pretend to lose time of other forums user while they are searching open question which is not answered,thanks for understanding

Migration from Oracle 32-bit to 64-bit on Windows

Hi,
Currently we have Oracle 32bit 10.2.0.2 on Windows 64-bit.
We want to convert oracle to 10.2.0.2 64 Bits on the same machine.
The procedure is quite simple but if we want to keep the same Oracle home it become complicated.
The Oracle 32 bit is installed on /oracle/SID/102 if we want to keep the home directory after the migration we have to install the oracle 64-bit software on /oracle/SID/102.
1. Can we install 64-bit binaries over 32-bit binaries on the same directory.
2. Do we have to deinstall first 32-bit binaries
3. Can we simply empty the /oracle/SID/102 and install 64-bit binaries and start the DB and run the conversion script ?
Thank you for you help.
Chak

Hello Stefan.
Thank you for your quick reponse.
Note 392800 describe how to de-install old oracle version after the complete installation of the new software which will be not our case because we want to de-install the oracle software before installing the 64-bit.
Normally the steps will be as follow
1. Use OUI to deinstall Oracle 32-bit
2. Install 10g 64-bit and 10.2.0.2 64-bit
3. Open the DB and run the conversion script
Is this procedure described in an SAP note ot at least supported by SAP ?
Another question : I guess when we d-install oracle using OUI it removes only the binaries not the DB or *.ora files (init, tnsnames,...).? what about the Oracle services, are they removed too ?
Thanks,
Chak

Migrating from eVC++4.0 to VS2008: Menu Bar not coming for class inherited from CProterty sheet

We are migrating code developed in eVC++4.0 to Visual Studio 2008. We are facing a Problem as descripted below. We are using Pocket PC 2003 emulator.
We are creating a class inherited from CPropertySheet. As below:
In Header File:
class COptionsSheet :
public CPropertySheet
      DECLARE_DYNAMIC(COptionsSheet)
#if(WINVER == 0x400)// This works for MenuBAr inherited from CDialog classes.
      CCommandBar m_cb;
#else
      CCeCommandBar m_cb;
#endif
public:
virtual BOOL OnInitDialog();
We are drawing menu bar on the property window as below:
In .CPP file:
IMPLEMENT_DYNAMIC(COrderSheet, CPropertySheet)
BEGIN_MESSAGE_MAP(COrderSheet, CPropertySheet)
ON_COMMAND(ID_CUSTOMER_COLLECTPAYMENT, OnCustomerCollectpayment)
ON_WM_INITMENUPOPUP()
ON_NOTIFY(GN_CONTEXTMENU, 0, OnContextMenu)
END_MESSAGE_MAP()
BOOL COrderSheet::OnInitDialog()
BOOL bResult = CPropertySheet::OnInitDialog();
m_cb.Create(this);//This we have changed for VS 2008 as menu was not appearing for class inherited from CDialog class as well. In eVC++
4.0 code we have used. Please see m_cb in header file discription
m_cb.InsertMenuBar(IDR_ORDER1);// This calis unable to draw mwnu bar
CMenu *pMenu = CWnd::GetMenu();
//pMenu becomes NULL in very next line as we are passing it as parameter below.
gPromotion.LoadSalesPromotions(pMenu,
"Sales", SRC_TRACE_START);
We tried this as well but it’s also not working:
CMenu *pMenu = new CMenu;
      BOOL cehckStatus = pMenu->LoadMenu(IDR_ORDER1);
SetMenu(pMenu);
      CRect r; GetWindowRect(&r);
      r.bottom += GetSystemMetrics(SM_CYMENU);
    MoveWindow(r);
Do we have to change or add something more for the menu bar in case of Property Sheet. Is there any change between eVC++ and Visual studio 2008 that we need to incorporate here.

I want to migrate Planning, Essbase and Shared Services. This is the first time, i am doing the migration. Please guide me in this situation. Its very urgent for me.
My Doubts
1) What are the files(In planning, essbase and shared Services) i have to copy for the migration?
2) What are the steps, i have to follow during the migration?
Please guide me in this situation. If u have any documents for migration, please share with me. This is my mail id : [email protected]
Thanks,
Lakshmi

Hi,
I am doing the migration for Planning. I am following the below stepts for migration. I am stuck in the middle.
The below are some steps to use in Migrating .
1. Create a new database on Production RDBMS Server for your planning application.
I created a new database (MIGRDB)
2. Configure a data source on Production Planning Server.
I configured the datasource
3. Create fresh planning application on Production Server and Ensure the admin is the same as your planning application on Development Server.
I created the new planning application in developement server
4. Go into the database tables for the planning app on Production Server and look at table HSP_USERS; store the SID value against user 50001.
How to find the SID for the new database? Here i want to replace the 50001 with new database sid value(step 1 - MIGRDB)
Please guide me in this situation.
Thanks,

Migration from G4 iMac to new(ish) Macbook

My daughter is graduating HS (yay!) and going to a great college in the fall (double yay!) and her grandma has given her a nearly-new white MacBook (2.16Ghz) (triple yay!) as a graduation present. Grandma, bless her heart, decided she needed a faster machine. Some people buy sports cars, Grandma likes having the newest and sleekest Mac. We love Grandma!
I am reading up on the steps to help daughter migrate her data from the G4 iMac (which also came from grandma) to the Macbook. It seems fairly simple, and I've done Target Disk before so don't think I can go far wrong but if anyone can check/correct these steps:
1. Backup everything important from the iMac. (mainly her photo and music libraries as all her work is HS related and she's happy to be rid of it) DONE
2. MacBook has grandma's account and preferences set, so we should restore from the install disks to get a fresh start. Right?
3. Once the MacBook is set up with her new account, migrate her stuff over via TDM. I think Migration Assistant won't work due to the disparity between machines.
4. De-authorize the iMac from our family iTunes account (already maxed out) and authorize the MacBook.
5. Install any needed software (MS Office & ?) from disks or .dmg.
6. Either pass iMac on to sibling or completely wipe it and sell it for $10. It has some ailment that is causing me to have to reset the PMU, so I suspect imminent component failure. Excellent time to upgrade!
Thanks for any tips, suggestions, or corrections!

Please read the following about migrating from a PPC to an Intel Mac:
A Basic Guide for Migrating to Intel-Macs
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC
System Preference add-ons
All Unsanity Haxies
Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5
Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior 4.1, TechTool Pro 4.6.1, SuperDuper 2.5, and Drive Genius 2.0.2 work properly on Intel-Macs with Leopard. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries. Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.
Additional links that will be helpful to new Intel-Mac users:

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking
will work better when moving from PowerPC to Intel Macs. The initial section below discusses Target Disk Mode. It is then followed by a section which discusses networking with Macs that lack Firewire.
If both computers support the use of Firewire then you can use the following instructions:
1. Repair the hard drive and permissions using Disk Utility.
2. Backup your data. This is vitally important in case you make a mistake or there's some other problem.
3. Connect a Firewire cable between your old Mac and your new Intel Mac.
4. Startup your old Mac in Target Disk Mode.
5. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
1. Set up a local home network: Creating a small Ethernet Network.
2. If you have a MacBook Air or Late 2008 MacBook see the following:
MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch, Late 2008)- Migration Tips and Tricks;
MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch, Late 2008)- What to do if migration is unsuccessful;
MacBook Air- Migration Tips and Tricks;
MacBook Air- Remote Disc, Migration, or Remote Install Mac OS X and wireless 802.11n networks.
Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder)
/Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder)
/Home/Library/Mail (copy the whole folder)
/Home/Library/Preferences/ (copy the whole folder)
/Home /Library/Calendars (copy the whole folder)
/Home /Library/iTunes (copy the whole folder)
/Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist
/Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data
Also in /Home/Library/Preferences/Microsoft
Credit goes to Macjack for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

Migrate from Google Apps to Office 365 with admin credentials only

Hi team,
We are migrating from Google Apps to Office 365. I know the normal procedure of migrating, but I want to know how to migrate from gmail to office 365 with administrator credentials. Normally for migration, we use user's mail ID and password in CSV file.
But I don't want to use users credentials, instead I want to use only Administrator credentials.
Thanks in Advance...

A third party tool such as MigrationWiz can accomplish this task. More information on how to set up administrative access can be found here:

Data Migration from CRM 5.0 to CRM 7.0

Hi Friends,
We are into a re-implementation on CRM 7.0. The old system was on CRM 5.0.
Since this is not an upgrade, the data will not copied over from the old system into the new system.
So, now I would like to know how to migrate data (master/transaction) from CRM 5.0 into 7.0.
I have read that we can make use of BAPI/LSMW/IDOC/XIF adapters to push info into CRM.
But, the customer wants all the historical data to be in the new system.
I think master data can be handled.... but how to migrate the transaction data?.... i mean the number ranges/document flow.. and other relationships.. how can we maintain the same links into the new system?
If it was a migration from legacy system into the SAP CRM, we could have gone ahead with new number ranges etc... but this migration is from SAP to SAP.
Also, we will have ECC6.0 connected to CRM 7.0. ANy additional things to be taken care of when the connection is live in DEV/QA/PROd instances?
Any pointers to this ?

Hi Gary,
As per my understanding, your data migration involves quite complex scenarios covering the CRM and ERP box. As the customer needs the old data to be present in the new implementation, the old data needs to be migrated from the CRM 5.0 to CRM 7.0. For the migration to happen, you need to setup the customization (like the number ranges,Condition Data Tables, etc ). Then only you can proceed with the data migration. Also, you need a proper backup plan as this involves proper backup of the data.
Once the setup is complete, you need to configure the ECC6.0 with the CRM7.0 system. Here also, you need to do a lot of settings and performing the Initial loading of the Adapter Objects. But before you proceed with the entire operation, the entire system landscape must be properly defined with appropriate settings.
My recomendation is to take help of SAP Consultants and data migration experts as they are the best persons to guide you on this. Also it would be great if you can go through the SAP Best Practices documents which are best repository documents to guide you on this.
Have a look on this link for an overview of the CRM Data Migration
http://help.sap.com/saphelp_crm60/helpdata/en/1a/023d63b8387c4a8dfea6592f3a23a7/frameset.htm
Hope this helps.
Thanks,
Samantak.

Migrating from NT MS SQL to Linux O8

I know I can export all my sql server data and scripts and such
and then import them into O8, but I was wondering if anyone has
seen any kind of migration tool that will just allow me to
transfer all my users, tables, dbs, sp's, etc..., to O8 on Linux
in one shot.
I d/l'd the Oracle migration tool, but it looks like it only
works with migrating from Oracle to Oracle. I haven't seen much
for this and was thinking it would definitely be something that
people will run into in the future since I'm sure I'm not the
only one who's trying/tried this. Right now I'm just transferring
everything via a small custom Java app. It would be nice to have
a gui java app for all of this :-) hmmm..

Active Directory Migration from 2003 to 2012 Process Flow

We are planning to migrate from Windows Server 2003 AD to Windows server 2012 Server for 6000 Users,
Can any one suggest on Following .
1)What is the Best and Safe Way to do Migration
2) What are the Precautions should take,
3) How much downtime it will take,
4) If migration Failed how we can revert to Earlier
5) How to do Migration Step by Step
Current Environment:
Domain Having One PDC(server 2003 R2) and 8 ADC(Server 2003 R2) in Different Locations
PDC having All FSMO Roles and Global Catalog
Exchange server 2007 was integrated to Active Directory
And some Application are integrated to Active Directory

1) I would recommend you first run a test of the steps in test before you do this in production. Otherwise your production becomes test.
2) By doing in test, you have taken a large amount of the risk out of the upgrade since, in test you should be able to look for any unforseen issues. The easiest way to test is to build a virtual fence from production and clone the DC's and member
servers that you want to test against (This is assuming you are running in a virtual environment). Ensure that you production environment is error free.
http://blogs.dirteam.com/blogs/paulbergson/archive/2009/01/26/troubleshooting-active-directory-issues.aspx
3) There should be no downtime at all, you can just extend the schema and then promote a new 2012 DC (I would recommend R2 if you can).
4) Before you do the schema extension you should take 2 backups on two different DC's. Taking two gives you less of a chance of a problem if one of the backups fails.
5)
Take a backup
Extend the schema
Join the 2012 R2 servers to the domain
Add the ADDS role to the 2012 R2 member servers
Promote the 2012 R2 DC's
Transfer the FSMO roles to the 2012 R2 DC's (Not required but recommended)
If you want to retire the 2003 DC's, then you will need to make sure that any clients pointing to the 2003 DC's for DNS are pointing to other DC's.
If you do retire the 2003 then you can think about updating the DFL and FFL of the domain and forest.

We currently have a 2003 R2 flat file server with multiple layers of nested network shares with over 2.5TB of data. We want to migrate to DFS on 2012 Server standard version with deduplication enabled. We have never worked with DFS and deduplication and
any white paper on DFS and deduplication would be greatly appreciated. Not finding anything on DFS step by step for 2012 and in particular migrating from 2003 file share to 2012 server DFS.

Thank you for the URL to your DFS write up. This was very helpful in my research of DFS. I have a couple of questions. Do I have to start DFS with two servers? I completely understand why you should have more than one server in the DFS pool (high
availability) but is it necessary? Also after setting up the two 2012 Servers with DFS, namespaces, and new shares managed by DFS manager, how do we migrate (move or copy) the existing shares to new server without losing the permissions? From what I've read
in your write-up all end users with have read and write permissions and admins have full. Also is there a best practice on how nested the shares should be setup within DFS? From looking at your write up the shares are one folder deep only. At this
company I'm migrating from a file server with shares 3-8 layers deep build up over the last 20 years.
