Upgrade/Migration Approach

Hi All,
We are currently having 2 node architecture for our 11i(11.5.10.2) instance with DB(10.2.0.4) & CM on one node and Forms/Web on another node with distributed appl_top in place on Solaris 5.10 servers. We would like to have a final version of R12.1.3 with 11.2.0.2 on RHEL 5 64 bit machines with only DB on one node and other apps services on another nodes.
Could you please confirm if the below approach is fine.
1) Perform OATM conversion on the source instance
2) Migrate the DB from 10.2.0.4 solaris 5.10 to RHEL 5 64 Bit to 11.2.0.2 by following the note 557738.1
3) Install the techstack for R12.1.1 on RHEL 5 64 Bit server
4) Complete the R12.1.1 upgrade
5) Apply the R12.1.3 patch
Also, Please confirm can I directly migrate the 10.2.0.4 database running on Solaris 5.10 to RHEL 5 64 bit server with 11.2.0.2? If its possible, do I need to follow the interoperability notes for 11gR2 with 11i on the source instance? Please confirm.
Thanks

Hussein,
One more question regarding the approach.
We are contemplating the option of using transportable tablespace/Transportable database as well
Since we have different endianess for source and target platform we can not go with Transportable database option.
We have the option to use Transportable tablespaces option by following the note 454574.1. My question is, is it possible to migrate using XTTS option for souce database from 10.2.0.4 to 11.2.0.2? I believe its not possible but wanted confirm. Do we have to migrate to 10.2.0.4 on target and then upgrade later. Please confirm.
Thanks

  • Upgrade/Migrate 9.3.3 Planning apps to 11.1.2.2

    I am in the next step of our upgrade from 9.3.3 to 11.1.2.2 and ready to migrate our Planning applications. I have read many of the posts related to this and have a general list of steps, but I have slightly different situation than what I have seen posted before.
    To summarize, we have installed 11.1.2.2 on new servers.  Our old 9.3.3 is still up and running on different environment.  I have sucessfully completed the following:
    1.     Foundation Services/Shared Services installed and up and running and users/groups successfully migrated.
    2.     Essbase and EAS installed and up and running.  All Essbase applications (except for the Planning apps), have been successfully migrated from 9.3.3 to 11.1.2.2.
    3.     Planning has been installed and is up and running.  While there are no Planning apps in the new system, I can open the Planning Administrator via WorkSpace.
    So the next step is to get my Planning apps moved/migrated from the 9.3.3 environment to the new 11.1.2.2.
    To complicate matters, we are switching from SQL Server repository in 9.3.3 to Oracle in our new 11.1.2.2.  So the first thing we did was to create a new Oracle schema for our Planning app repository and using SQL Developer migrate wizard, we copied/migrated the tables and data from the old SQL Server to Oracle.  It appears that all the tables and data were successfully copied into Oracle.
    Our old Planning application is called PlanTest. The application owner is a native user called planadm.  My intended migration plan (and my questions) are:
    1.     Do I create a new blank Planning app called PlanTest using native account planamd in 11.1.2.2?
    2.     If I use my new Oracle repository for this blank app, will it wipe out the old converted data or will it try to upgrade/migrate it?
    3.     Or..should I take a backup of my new converted repository first.  Then drop/recreate the Oracle Schema (so no tables) and let Planning build the repository when I create the blank Planning app?  Then capture the owner SID in the new HSP_USER table.  Stop Planning. Then overlay the database backup of 9.3.3 over the newly created repository and replace the owner SID info. Then Restart Planning.
              ** My concern:  Is the Planning app repository table structures the same between 9.3.3 and 11.1.2.2?
    4.     Open Planning and hope that the application PlanTest appears!
    5.     Use Planning upgrade Wizard to finish the migration and upgrade the repository.
    6.     Push/Create app to Essbase.
    7.     Export data from old app to .txt load file and reload into new Planning cube.
    8.     Convert/Migrate Business Rules using info from John's blog.
    I am sure I missed something.  Any suggestions or comments on these steps would be appreciated.  Bottom line is I need to get this app (and several others) migrated successfully with all metadata, security, forms, rules etc. working.  Rebuilding them from scratch is NOT an option.
    Also, to clarify.  This is a Classic Planning app.  We are not using EPMA.
    Thanks,
    Mike

    Following the steps, the upgrade/migration of the Planning application worked successfully.  The app and forms were all migrated and was able to push to Essbase application successfully.  The only issue was security.  While the users/groups seem to appear in the migrated Planning app, none of their security access/filter info migrated.  We have Planning security defined down to the member level in the application and it appears none of that successfully migrated, so we would need to manually re-assign all of that security.  Any thoughts of what may have happend or step I may have missed?
    Also have moved on to attempt migration of the Business Rules to Calc Manager.  Using John's 2nd alternative method from his blog, I export the rule from 9.3.3 EAS to HBRRules.xml file, copy it to the appropriate 11.1.2.2 folder, select "Migrate" on the PlanTest planning app in Calc Manager, select the app and Plan type and all seems well with the Import screen even indicating that the Rule and variables were Inserted.  But I never see the rule appear.  Could this be an "owner" issue or is there something I need to do to the .xml file before the migration step?

  • Confuse on PR & PO data migration approach new to MM module

    Hi All,
    I'm pretty confuse with the PO data migration approach when it comes to PO is GR or partial GR or GR&IR. I'm hoping that someone can enlighten me. i understand that we typically don't migrate PO when it is GR & IR, FI team usually will bring over to the new system as an vendor open item in AP. How about the PR or PO which have gone through or half release strategy? What is the follow up process?  I have created a criteria table below. How Could someone point me in the right direction? Thanks in advance.

    Regards,
    John

    Hi John,
    The approach that i have followed recently is that we have considered PO as the base document and converted other documents based on the PO condition. This means you first need to see if the PO is to be converted or not. Then you can proceed to convert the related documents like PR, Agreement, Info record, Source list, etc.
    Also open qty for PO should be considered for Material and Service line items both.
    Once a GR/SES is created, it gets updated in the PO history table EKBE with its related transaction/event type.i.e. EKBE-VGABE = 1 for GR and 9 for SES. Quantity and value also gets updated in case of material and services. You can compare this consumed quantities with PO quantity.
    Please see below from SCN and let me know if you need more info on PR or PO conversion.

    Hi Anurag,
    Thanks for your questions.
    1:Is there change in DB architecture as CUIC is the only option as compared to previous linux version UCCX ?
    I assume this is from the tables regarding historical data. The database schema essentially remains the same since UCCX 9.0 had CUIC too and we had a seperate DB Space for CUIC and we still continue with that. The traditional historical tables remain and the replication process remains the same too.
    2:Is there any version change for Linux OS used as VOS,
    The Linux version is Red Hat Linux 5. To be precise:
    [root@uccx10pub /]# cat etc/redhat-release
    Red Hat Enterprise Linux Server release 5.7 (Tikanga)
    3:Is there any API architecture change in UCCX 10 from previous releases ?
    I can answer this more of an overview. The only enhancement in the API side is the introduction of REST API step in the script editor. You can now make REST calls from the script and this ofcourse opens up a whole new world of possiblities.
    4:Since from UCCX 10 , we can only use either CAD or Finnesse at one  time, whats the impact of changing this after some time in production,  let say , i used CAD for 2 months and then i decided to move to Finesse,  whats the impact ? or is it a smooth change as switching CUIC and HRC  in previoius release ?
    For the scenario you mentioned, there is absolutely no problem. The point to note is that the Finesse services are activated/deactivated but the CAD desktop services are ALWAYS running. The only condition to keep in mind is that you can use ONLY ONE type of agent desktop at any time.  Also if Finesse is not used and CAD operations are used extensively, it is advisable to shutdown the Finesse service.
    5:Is 3rd Party UCS hardware supported by UCCX 10 instead of using Cisco manufactured UCS , can i use HP hardware for Virtualisation ?
    Yes, it can be used. This is something called as "Third party specs based specification". The most important things seen for compatibility are:
    Inter CPU Model
    It it is on thVMWare Hardware Compatibilty List
    You can get more information about this on the "Can I use this server?" section of UC Virtualized Hardware page:
    http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware#.22Can_I_use_this_server.3F.22
    6:Is Host name change supported?
    Yes, the hostname change is supported. The prcocedure is documented in the UCCX 10.0 Administration Guide:
    http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_10_0/configuration/guide/UCCX_BK_W1AF9DDD_00_uccx-admin-guide-10.0.pdf (Pg 168)

  • Upgrade/Migrate AS 10.1.2.2 Identity Mgmt, Forms, Disco to Fusion MW 11g

    Hello All,
    Need info/steps how to upgrade/migrate AS 10.1.2.2 Identity Mgmt, Forms/Report, Disco and Portals to Fusion MW 11g to new servers.
    We're currently running AS 10.1.2.2 Identity Mgmt, Forms/Report, Disco and Portals on Suse SLES-9 64-bit OS.
    We're currently running AS 10.1.2.2 Portals on Sun Solaris 8 64-bit OS.
    Fusion MW 11g does NOT support Suse SLES-9 or Sun Solaris 8 64-bit OS.
    Our Sys Admin said it's complicated to upgrade Suse SLES-9 to Suse SLES-10 OS on the same box.
    We'd like to install Suse SLES-10 OS on a NEW SERVER and upgrade/migrate AS 10.1.2.2 Identity Mgmt, Forms/Report, Disco and Portals to Fusion MW 11.1.2.
    We'd like to instal Sun Solaris-10 OS on a NEW SERVER and upgrade/migrate AS 10.1.2.2 Portals to Fusion MW 11.1.2.
    Have anyone done this upgrade/migrate at the same time?.
    We opened an SR with Oracle Support but the answers are not quite clear so If someone had done this upgrade/migrate before then it's very helpful.
    Any helps?.
    Thanks,
    Tom

    Both Infra and portal database is going to be in the database. You need to get the database copied over to new server and select upgrade option

  • Data migration approach for Scheduling Agreements

    Hi Zenith
    You might find useful information here: IS-U data export (extraction) for EMIGALL.
    I've done numerous IS-U migrations in the last 10+ years, but never one from IS-U to IS-U.
    One main questions to start with: Are the two systems on the same release level?
    If they are not and it would be too much effort to get them onto the same release level I would think creating your own extract programs and using the Migration workbench (EMIGALL) is the way to go.
    If they are on the same level, there might possible other ways to do it, dependent on the differences between the two systems (mainly around customising). Assuming there are significant differences - otherwise why would you bother migrating? - there's the high probability that using EMIGALL is the way to go as well.
    Yep

  • Upgrade/Migration using PCD from 8.6 to 10.5

    Customer has a cluster with a publisher and 7 subscribers.  Infrastructure is a mix of 6 spec-based VM servers and 2 MCS servers.  I am considering using PCD, but I have the following questions:
    With the mix of virtual and MCS servers, do I need to do a migration vice an upgrade?
    If I do the migration, does this essentially double the virtual real estate required until the migration is complete and I can delete the 8.6 servers?
    Any other gotchas that I should be aware of?  This will be my first PCD upgrade/migration.
    Thanks in advance,
    Nathan Richie

    PCD will install and push the info one server at a time, you can either keep the same IP addressing and hostname, or change it. If you're going to keep the same, you need to build a separate network with ALL the services you have in production and make sure you do not cause a conflict by separating the networks.
    If you have the CAR DB at full capacity, delete the records to avoid timing out.
    And as Aman said, 10.x and above are ONLY supported over ESXi, no baremetal support.

    Thanks Mende1; I know that PPC apps won't function on Intel machines but I can migrate the Universal apps, right? There is such a large gap between Tiger and Mountain Lion - can I still migrate files directly from one to the other taking the Universal apps as well? Sorry, I'm not very computer savvy!

  • OCS 2007 to Lync 2013 migration approach & steps

    Hi,

    Hi Nmits,
    Since it is not supported to migration from OCS 2007 to Lync server 2013 directly, you have two ways to complete the migration process:
    Migration from OCS 2007 to OCS 2007 R2 first, then migration from OCS 2007 R2 to Lync server 2013.
    Migration from OCS 2007 to Lync server 2010 first, then migration from Lync server 2010 to Lync server 2013.

  • Upgrade + migration from nw04 on windows 2000 to nw04s on windows 2008

    Dear all,
    I need to upgrade and migrate my nw04 java system from windows 2000 to nw04s on windows 2008.
    From the PAM I can see that NW04 is not supported on windows 2008 and that nw04s (7.0) is not supported on windows 2000.
    So, which is the correct upgrade path? Do I need an intermediate win 2003 server which is supported from both the releases?
    Thanks and regards in advance
    Federico

    Hello my friend
    This will be a very interesting project for sure. As you know, kernel 640 is not supported on win2008 and 700 is not supported on win2000, so here there must be a win2003 as a transition platform for this upgrade+ migration, not to mention migration from 32bit to x64 is also involved. You didn't mention the DB versions in source and target systems, as well as the SAP product you're trying to go with. Here's a brief checklist right now for what I can think of, once you're back with more details then let's make it intact:
    I assume your source OS/DB is win2000SQL2000 32bit, target one is win2008SQL2008 x64.
    1. Install a win2003 x64 server and SQL2000 32bit;
    2. Install a new SAP instance same as your source system release in 32bit compatible mode;
    note: if the system being migrated is BW, then be aware of that you might want to bring new features in SQL2008 of row compression and table partitions.
    3. Detach the source DB from old SQL2000, and attach it to new SQL2000; some post configuration for DB copy will be required (STM tool). Now you've finish a migration from win2000 to win2003 32bit;
    4. Start upgrading NW04 to 7.0, 640 to 700, find details in upgrade guide; Now you have your 700 instance on win2003 x64+SQL2000 32bit;
    note: since release 701(700 EHP1) is available now, which you might want to upgrade instead of 700.
    5. Change the collation 850BIN2 for SQL2000 32bit, detach DB;
    6. Since migration from 32bit to x64 cannot be done smoothly, now you have to uninstall everything and reinstall win2003 and SQL2008 x64, followed by a new 700 or 701 instance;
    7. Attach the source DB, post configuration for DB copy will be required (STM tool); Now you have your 700 or 701 instance on win2003 x64+SQL2008 x64;
    8. Detach the SQL2008 DB;
    9. Now go to your target win2008 OS, install SQL 2008 x64 and new 700 or 701 instance;
    note: there might be some restrictions for NW 7.0 on win2008, go with the latest release (SR3 or newer).
    10. Attach DB to this final OS/DB version: win2008 x64+SQL2008 x64, post configuration for DB copy will be required (STM tool).
    Helpful?

  • ECC6.0 EHP4 upgrade best approach

    Hi,
    What will be best approach for the following scenario:
    Source:
    OS - Windows2000,32bit
    DB - Oracle 10g
    SAP - R/3 4.7Ent,NUC
    Target:
    OS - Windwos2008,64bit
    DB - Oracle 11i
    SAP - ECC6.0 EHP4,NUC
    Any suggestions?
    Thanks and Regards,

    Hello,
    >> After step1 is it really required to wait for 4 weeks to get the system stable before the start of upgrade as per the SAP recommendations?
    It is recommended and you should but you are not forced to if you are comfortable in three weeks as well
    >> For step4,can we follow standard backup/restore method after the upgrade is completed?
    Yes, it works fine. See an SAP Note for Win 2003 to Wind 2008 migration. It will be homogeneous system copy and backup/restore can be utilized.
    >> If we think of performing the unicode conversion,then which of the following methods mosts applicable?
    Combined Unicode and upgrade at step2 or perform the upgrade first,then export the system and import in Windows2008 as unicode?
    If you include Unicode Migration as well, then you have FOUR major things to do (after migration to 2003 64 bit) -
    1. Oracle Upgrade
    2. ECC Upgrade
    3. Unicode Migration
    4. Win 2008 Migration
    Option 1-
    A) You can combine the ECC upgrade with Unicode migration along with Oracle upgrade to 11g (Step 2 & 3) in 'Combined upgrade and Unicode' Procedure.
    B) Then you carry out win 2003 to win 2008 migration by either EXPORT/IMPORT or Backup/Restore
    Option 2 -
    A) You go ahead with only ECC upgrade (only the step 2)
    B) Then you go ahead EXPORT/IMPORT for - Unicode Migration + Win 2003 to Win 2008 + Oracle upgrade to 11g - all in One go
    I would go with Option 2.
    Thanks
