Hi
Your version of DB2 is almost outdated, you should consider upgrading it too to v11.5.9.
The approach that I took for WAS/BAW was to keep the same host name on the new VM (at least in the etc/hosts file until you can update the DNS entry), then reinstall the same version that I had on the RHEL 7 onto the RHEL 9 machine (same WAS, BAW, JAVA if you're not using the bundle one, same fixes), and copy the WAS profiles and important files to recover... and then you should consider upgrading the products to latest.
Important if you follow that path, you need to keep the same installation path during the WAS install (I had initially changed mine, and nothing was working anymore)
On the RHEL 7, you need to copy these folders/files (my WAS is installed in /opt/ibm/bpm) to the same place onto the RHEL 9 machine
- /opt/ibm/bpm/profiles
- /opt/ibm/bpm/properties/profileRegistry.xml
- /opt/ibm/bpm/properties/fsdb
If you have CaseManager enabled, you may have some other folders (I had a LDEPS folder)
Once copied, you can restart WAS/BAW as normal
Let me know if you miss some info
Cordialement,
Best regards,

Hi QuikJean,
We have a similar requirement to migrate from RHEL 7 to RHEL 9, as the Linux team is not willing to perform in-place OS upgrades. Therefore, we have procured a new RHEL 9 server. The approach for this migration needs to be finalized, especially since we need to install new versions of BAW and WAS on RHEL 9. Additionally, we need to figure out how to point these new installations to the existing database and DE environment creation which will be pointing to same data as old is referring . Can you please suggest a detailed approach to achieve this migration?
Current Versions:
-
BAW: 21.0.3
-
WAS: 8.5.5 FP 24
-
DB: 11.1
Regards,
Mahesh

Hi,
I had a similar case where I was still on RHEL 7 but my BAW was pretty up to date (23.0.2).
I already knew the procedure to recreate a node so I took the path of building a brand new RHEL 9 VM, reinstall WAS/BAW, move the profiles and everything needed. It went smooth and it's pretty fast. You have quite a small downtime because you can prepare a lot in parallel while your old RHEL 7 is still running.
Let me know if you need some details of what I have done to move the WAS profiles

Hello All,
Looking for suggestions. Customer wants to migrate on-prem BAW 21 to 24 using a cloning approaching because they also need to upgrade their RHEL version from 7 to 9. They cannot do in-place upgrade from RHEL 7 to 9. They want to
- Provision a new machine with RHEL 9 installed.
- Clone 21 installed on the current RHEL7 to the new RHEL 9 machine.
- Once BAW 21 is cloned on RHEL 9 machine, they will do an in-place upgrade of the BAW 21 version to BAW 24.
I see in system requirements BAW V21 is not supported for RHEL9 machine. Can you suggest an approach - migrate/upgrade from V21 to V24 or do in-place upgrade to V23 and clone/upgrade to V24 in RHEL9 ?
Thanks,
Goutham M.
