Migration 11.5 to 12.1 Checklist

Hi,
One of the checklist points is to verify that the current structure of xMII 11.5 applications matches the project structure in SAP MII 12.1 Its been a while since I worked in 11.5, can somebody explain in detail about the folder structure in 11.5 and how to match it up with 12.1.
Regards,
Chanti.

Checklist for migration from oracle 9i to oracle 10g DB

Hi all,
My previous DB was Oracle 9i.I want to migrate it to Oracle 10g DB.
So can anybody provide me the checklist for the same ?
Thanks in advance....

It doesn't matter how long this process may take to read the entire upgrade documentation. You are supposed to perform this procedure first on a testing environment prior to perform it against the actual production database, you can take all the time you need to customize trim and tailor the procedure to your particular environment requirements. Don't expect anybody else to provide a shortcut, you will find at the end it will take you more time to correct missing upgrade steps and you will -most probably- have to read much more google references and metalink documents that will size bigger than the upgrade guide.
I suggest you to read through the upgrade document, and don't look for shortcuts. I also suggest you to document issues you may find when performing the upgrade. In my particular scenario I had to deal with an ORA-04030 error, among other things after I performed an upgrade process. You may want to take a look at the not documented Issues I had to face after a production upgrade, and even though I read through the upgrade guide and performed several testing upgrades, there are issues such as user's actual workload that cannot be accurately measured in a testing environment.

Link/checklist for migrating applications from Oracle 9i to Oracle 11g?Help

Hi all,
We need to perform an impact analysis on migratiing an application from Oracle 9i to Oracle 11g. Does any of you have a detailed checklist to follow, in terms of queries, PL/SQL statements, optimizer etc. etc., when attempting this migration. We require something more specific from the application point of view rather than a DBA point of view.
Additionally, we have queries written extensively with rule hints. Should there be a special consideration for the same since now we are moving to CBO in 11g
Even if any one has a link, that would help. Thank you so much!

Hi Nikhil,
Thanks Xaheer,You're welcome :)
I'm going through the link: http://download.oracle.com/docs/cd/E11882_01/server.112/e10819/toc.htm
But it still mentions stuff from a DBA angle. I need from an application angle.
Do I need to change my queries taht are current written with RBO? Do I need to change Pl/SQL blocks ?Please refer tech below notes:
*1)TROUBLESHOOTING: Server Upgrade Results in Slow Query Performance -- 160089.1*
*2)TESTING SQL PERFORMANCE IMPACT OF AN ORACLE 9i TO ORACLE DATABASE 10g RELEASE 2 UPGRADE WITH SQL PERFORMANCE ANALYZER -- 562899.1*
Before upgrading your production database, please perform upgrade of test database and do complete testing.
Hope helps

Need Checklist for migrating MS SQL 2005 SP2 to MS SQL 2012

Dear Member,
We are in process of migrating our MS SQL 2005 SP2 db engine / SSIS/SSRS services to 2012.Need to know steps/checklist and experiences of migration.
I have read on Microsoft site (http://msdn.microsoft.com/en-in/library/ms143393(v=sql.110).aspx), that we can only migrate SQL 2005 with SP4 to SQL 2012.Do we need to upgrade first existing 2005 SP2 to SP4 and then start migration.
Regards,
Mahesh

Hello,
Yes, you need to apply SP4 first, if you choose to perform an in-place upgrade.
You have the option to perform a side-by-side upgrade too. Please refer to the following guide:
http://download.microsoft.com/download/9/5/3/9533501A-6F3E-4D03-A6A3-359AF6A79877/SQL_Server_2012_Upgrade_Technical_Reference_Guide_White_Paper.pdf
Hope this helps.

Database migration checklist | How to move from 8.1.7 to 9.2.0

Where can I find official Oracle migration checklist. For migrating our 8.1.7 db application to 9.2.0 db (or something similar to that).
As a test we used Oracle export and import, migration looked fine but performance was poor for some area of our OTM application, explain plan for some SQL are very different in 8i and 9i. 1 min query taking over 4 hours and so on. We must be missing something curtail so need migration checklist now.

For better layout:

Checklist of what has to to be done when migrating an complex SAP environme

Hello
I wander does anyone has a checklist of what has to to be done when migrating an complex SAP environment to new hardware. We plan to migrate ECC, XI, BW, CRM IS-Utilities to new platform(e.g HP Superdome ).
Some of system now are consisting of more application servers and one database but this is more or less because of performance issues which became in long time period.
e.g. one of things to be checked are jobs explicitely dedicated to servers. I am sure there is a project plan of other things to be checked but i do not find it
Please help

> I wander does anyone has a checklist of what has to to be done when migrating an complex SAP environment to new hardware. We plan to migrate ECC, XI, BW, CRM IS-Utilities to new platform(e.g HP Superdome ).
If your source system is currently on the same platform (HP-UX) then it's just a matter of moving the database or presenting the LUNs to the new system.
If you use a different operating system and/or database on the source system then you must buy a certified migration consultant who will do the migration on-site (see http://service.sap.com/osdbmigration --> FAQ). If you do this on your own you'll loose SAP support for problems during the migration and for the target system.

LCM Migration validation checklist

Hello there,
does anyone have an LCM Migration checklist used to validate that the migration was successfull ? also lists any common errors to look for that the LCM console would not report on ? do you have a list of these potential migration errors that are not usually reported or flagged by LCM?
Thx

I wouldn't trust status field in LCM progress report. Sometimes it says import was successful, but it actualy hasn't been. I'd pay special attention to BRs (in my experience, delete them on the target before import), Task Lists (getting "Success", but in target app they are not correct, form links are usually missing), Planning Units (annotations and logs don't always go over), etc. Get the idea?

Error while cancelling a migrated PO

Hello All,
We are trying to cancel a migrated PO. While cancelling, we are getting an error Document control failed due to error in [DOCMGR-CANCEL] with a return code of [OTHER].
I referred the note Master Note of Fixes for Error - Document control failed due to error in [DOCMGR-CANCEL] with a return code of [OTHER] (Doc ID 1482447.1)
As per point no 4 in this note I checked the PO Document Approval Manager.
The Note says
*3.Verify the number of target processes should be equal to the number of running processors.*
which is equal in our case.
Also, in the Status column, you should see 'Activate concurrent Manager'. That means the manager is running or active.
In our case the Status column is blank. This is the only difference that I find in the resolution steps provided in the note.
Can this be the cause for our problem? Because we are not facing this issue for all the POs.
Thanks in advance for your help

Guide to migrating a HV 2012 cluster managed by VMM to HV 2012 R2 + VMM R2

Hello everyone,
I have a task on hand and even after searching the ‘net for quite some time, I have not come across a solution listed on one page. I hope this thread becomes a “Guide to migrating a Hyper-V 2012 cluster managed by VMM 2012 to Hyper-V 2012 R2 + VMM 2012
R2”.
My searches did find these useful threads but they do not have all the information I need:
http://social.technet.microsoft.com/Forums/systemcenter/en-US/eb824c20-9632-4ec9-9a71-2d1717e44a81/migrate-from-2012-to-2012-r2-cluster-with-vmm-2012-r2?forum=virtualmachinemgrclustering

http://social.technet.microsoft.com/Forums/systemcenter/en-US/5d4103b5-6491-40d2-b52e-7fffde9580ff/vmm-2012-sp1-supported-to-manage-windows-server-2012-r2-hyperv-cluster?forum=virtualmachingmgrhyperv
So let me start by listing what I have right now:
I have a 4 node cluster running Hyper-V 2012 SP1 (the free, core edition).
It is currently being managed with SC VMM 2012 SP1.
99% of the VMs are running on CSVs cut off a Fiber Channel SAN. I have some VMs on local drives and they are not HA.
Everything is in production. I have around 90 VMs total.
I do have capacity to take up to two HV hosts out of the cluster and still survive just fine.
I also have two other spare servers which have no OS on them.
What I don’t have:
I do not have SCOM or DPM or any other SC component.
Well, I used to have SCOM 2012 but I uninstalled it and removed it. Long story, don’t ask! I do plan to install SCOM 2012 R2 at some point soon.
Here is what I want to do:
Upgrade both the cluster and VMM to 2012 R2 version.
This time, I want to use Server 2012 Datacenter edition (with GUI).
I plan to join the spare servers to the 2012 R2 cluster.
Here is what I have learnt up until now (and correct me if I am wrong):
The steps I need to take to accomplish all this are:
Upgrade VMM 2012 to VMM 2012 R2 version
Eject at least one host from the cluster
Install Server 2012 R2 on that server.
Configure a one server (or more, if possible) cluster running 2012 R2
Give that server the same old CSVs
Use the “Copy cluster roles Wizard” to copy VMs from old cluster to new cluster. However this will incur downtime.
I have not started doing all this because I am not 100% sure on some things.
Here is the list of my questions:
1. About step #1: Upgrade VMM to VMM R2 version
Is there any reliable / official guide out there for this? I have seen these on the net:
http://technet.microsoft.com/en-us/library/dn469607.aspx
http://www.systemcentercentral.com/migrating-from-vmm-2012-sp1-to-vmm-2012-r2-step-by-step-upgrading-to-2012-r2-series/
The problem I see is that none of them talk about upgrading a clustered scenario. Do I assume that the steps of upgrading VMM 2012 to 2012 R2 are the same with or without a cluster?
On the server I eject from the cluster, do I upgrade the OS or do a fresh install? I prefer doing a fresh install.
2. Is there a way of doing all this with no downtime?
I am worried about needing downtime for the last step “copy roles…”. I wish there was a way of migrating the roles (VMs) without any downtime.
3. Anything I need to worry about?
I wonder if I need to be careful about granting access to the CSVs to the new R2 Cluster. Will that cause any problem?
Any inputs on this topic are highly appreciated! I promise to update the first post so that it becomes a guide as I get corrections and inputs from everyone :-)
Thanks!

Time to tackle the actual Hyper-V Cluster migration:
So by this time, I have two nodes in the old Hyper-V 2012 cluster managed by SC VMM 2012 R2. I wiped out the OS on the other 2 nodes and installed Windows 2012
Datacenter on them. This time I am not installing the Core edition for Hyper-V. After working with Core for a year or so, I feel Core gives way too much trouble for very little gain.
Now I plan to follow a technet document which describes how to
migrate virtual machines from a Hyper-V cluster using Cluster Shared Volumes (CSV). Although this document does not describe VMM I think VMM should be able to use those migrated VMs. Here is this migration strategy in a nutshell:
Create a new cluster using 2012 R2
Present the existing CSVs to the new cluster.
Leave the disk offline on the new cluster.
Use the copy cluster roles wizard in Failover Cluster Manager to copy VMs from old cluster to new cluster.
Virtual machines are created on the new cluster but are not turned on.
Turn off the virtual machines and take the disk offline on the old cluster and then on the new cluster you need to enable the disk and start the virtual machines.
Hmmm…sounds pretty involved to me. Well let’s get on with it. First things first…in order to use this migration strategy we need to create a new cluster.
Here are the steps I took to create a new cluster:
Install 2 Windows 2012 R2 on the same 2 servers I ejected from the old cluster.
Correct drive letters of local hard disk drives and optical drives, if needed.
Update them.
Setup networking. Take care of main network, heartbeat for cluster and iSCSI networks (if applicable). Here are some best practices:
http://blogs.technet.com/b/askcore/archive/2014/02/20/configuring-windows-failover-cluster-networks.aspx
http://blogs.msdn.com/b/clustering/archive/2011/06/17/10176338.aspx
https://social.technet.microsoft.com/wiki/contents/articles/9711.hyper-v-network-design-configuration-and-prioritization-guidance.aspx
http://technet.microsoft.com/en-us/library/dn550728.aspx
Make sure your bindings order is correct. I had to correct mine because by default, the heartbeat network was at the top!
I also followed this checklist of Hyper-v’s best practices.
http://blogs.technet.com/b/askpfeplat/archive/2013/03/10/windows-server-2012-hyper-v-best-practices-in-easy-checklist-form.aspx
Much of the stuff in there is very relevant.
Add the domain account used for host management and the SCVMM service account to the local admin group on the 2 new servers.
Use SC VMM manager to install Hyper-V role on the two new servers. VMM can do that as a part of the “Add Host process”.
In VMM, right click on “All Hosts” and click on “Add Hyper-V hosts and clusters”. Go through the wizard and add the two new servers.
When I did this, it failed. I got three errors, Error 10441, Warning 10444 and warning 26179.
I logged into one of the new servers locally and from Server Manager >> Dashboard >> Add roles and features.
On the “create virtual switch page, I selected the NIC connected to the main company network (as this time I have only one NIC for the company network, you should have at least two).
Unfortunately, even this time I get an error: Access is denied: 0x800700005
This is very strange because I am already logged on as an admin here.
Now I started checking for windows updates. I remembered that the checklist above also has a set of recommended updates. There was a huge 890MB), cumulative update available KB2919355. I installed and restarted after that.
I also installed the feature “Multipath I/O” since I was getting the “warning 26179”.
After this installation, I ran windows update again. No available updates.
Now I went back to VMM. I really want to enable the Hyper-V role using VMM. So I repeated step # 8. Interestingly, this time I did not get any error. VMM rebooted the host automatically. Yay!
Now I repeated steps 14 to 16 on the second server. Worked fine!
At this point we are ready to create a new cluster using the two nodes. I followed this document:
http://technet.microsoft.com/en-us/library/gg610576.aspx
At this point I ran into a problem. I talked about it on my thread: When I try to create a new HV cluster using the "Create HV Cluster" wizard in VMM, it comes to a screen titled "Storage" where it shows all the existing LUNs as disks and
it says "select the discs you want to cluster". That is all good but at the bottom it says "Any data on the disks will be overwritten”. Of course I want to keep my data intact so I can use the copy cluster roles wizard later on! How can I create a new cluster
which uses the same disks as the old cluster WITHOUT wiping out the disks?
Ok so I did not get an answer on the forum, so I decided NOT to take a risk and do a quick test. Here is what I did: I masked/unexported all CSVs. Then I created a test CSV, put some data on it and proceeded to create a cluster using that
CSV and a quorum/witness disk.
This time on the storage page, For the test volume I checked the checkbox under CSV. I left the format boxes unchecked << THIS IS WRONG read below for updates
The attempt failed. Somehow the test CSV got configured as a local disk on host #1, it was showing up as NTFS instead of CSVFS. The VMM cluster creation process stopped. I found out that both the CSV and the quorum disk were online on the
node #1. I made them offline.
Retried , got the same error as last time : Mounts storage disk on (servername).
FINALLY I realized that step # 21 bove is WRONG! You need to select “Do not format” under the file system column. This will leave the CSV untouched.
Unfortunately, even this did not work. So I just took away ALL CSVs and tried to recreate the Cluster. It STILL did not work! LOL! The error is 25303
I corrected the permissions as this:
ON the HV hosts, inside local administrators group add VMM service account, Host admin account and VMM server’s computer account
Inside “Virtual Machine Manager Servers” group add VMM server’s computer account
Unfortunately, it still did not work! The error is 25303 (same). I looked everywhere including all the logs (system and security) nothing there. I searched on the net but never found a solution. Eventually I accepted defeat and tried to
create a cluster from outside VMM…using “Failover cluster manager”
Even then I got an error! It seems to me that it failed on creating the computer name of the cluster in AD.
I tried it again with a different computer name in AD…something which had never been created earlier (I had mistakenly created a computer name for the cluster and then deleted it). This time it worked! However I got an error that the witness
disk was not created because it does not have an acceptable file system. Hmmmm.,….I had not formatted the witness disk since I thought the cluster wizard will do it. I created a Witness disk later, manually.)
Interestingly, when I opened VMM again, I see the cluster in there and I am able to manage the cluster from within VMM…interesting!

Migrating from 8i to 11g

Dear all,
I would like to know which is the best method for migrating 8i database to 11g..? (Exp/imp, Manually ( Both the OS are Same) or DBUA)
If you are going for exp/imp.. Can we do it directly?
OS is HP unix
Database size would be around 10 GB.
Thanks in advance
Nishant

First of all direct upgrade is not possible from Oracle 8i to 11g.
What's your four digit of the Oracle 8i Database? indirect upgrade can be done as the foolowing version,

How to migrate data from oracle 9i database to new machine 11gr2 RAC ASM

Hi Expert
I need your expertise to advise me what is the best method to move data from oracle 9i database to new machine running oracle 11r2 RAC database with ASM.
Currently my production server running on HPUX ORACLE 9I database with normal file system. My new server is running SUN SOLARIS SPACR 64 bit ORACLE 11gr2 RAC with ASM. What is best method to move data over so it will be consistent. Any guide can refer.
Regard
William

Hi William,
See the note in metalink Migration of Oracle Database Instances Across OS Platforms [ID 733205.1] to saw the Endian Format of your OS. If is the same you can use the RMAN to convert the database to another OS, if not the only option is using export/import (Transportable Tablespaces).
To upgrade from 9i to 11g, see the note 837570.1 - Complete Checklist for Manual Upgrades to 11gR2.
To migrate your FS to ASM the only way is using RMAN, so see the note - How to move a datafile from a file system to ASM [ID 390274.1].
Hope this help you.
Best Regards,
Ruben Morais
