Hello Experts,
We have plan to Migrate of SCM DB2 DB from AIX to RHEL7.
Our LiveCache LC is on SUSE Linux & will not migrate to RHEL7 as per current design unless, otherwise this combination is not supported ( Exploring more on supportability aspects).
I have below questions:(based on assumptions that LC will not be migrated)
1 - Only exporting & importing SCM DB is sufficient? If Yes, can someone outline LC related steps that I still need to perform in this scenario.?
2 - Since I am assuming here that LC will not be migrated do I still need to runreport /SAPAPO/OM_LC_DOWNLOAD_UPLOAD before & after SCM DB Migration to download & upload LC Objects to & from SCM DB respectively?
3 - I am checking on PAM & with SAP, meanwhile if someone already know - Is below combination of Target is supported ?:
SAP SCM application -- SUSE Linux
SCM DB2 DB -- RHEL7.1
SCM LC - SUSE Linux
Best Regards
Sachin
Hello Sachin,
If the liveCache will be not migrated, and you will not change the liveCache server, then you dont need to run the liveCache download/upload steps.
For the project I recommend to run the steps:
- bring the SCM system to the consistent status;
- Schedule downtime. Stop the liveCache in LC10.
- Create the liveCache & SCM DB backups in sync before to start migration.
- Migrate the SCM DB.
< review SAP note -
886103 | System Landscape Copy for SAP SCM |
>
- Start the SCM system.
Check the connection to liveCache in LC10-> Integration.
Start the liveCache.
Test connections in /ndb59, //om13 -> checks.
- Run the consistencies checks for the APO data & clarify via SAP message, if the inconsistencies occurred, before to release the system to users/CIF.

Hi Natalia,
Thanks for the response & the information.
I was busy with SANDBOX all these days & could reply before.
I am going to Migrate DEV system next week.
I have one question on your reply "bring the SCM system to the consistent status;"
What exactly do we need to do here?
Run program - /SAPAPO/OM_LC_DOWNLOAD_UPLOAD
& perform consistency checks in the section A of this report.
Can you please confirm on this part?
Thanks
Regards

Hello Sachin Bhatt,
"bring the SCM system to the consistent status;":
- Apply all recommended notes, SAP note -

- Check those & repair them.
- If any further questions/issues
