We are about to upgrade our CMOD environment running under RHEL 7.9, to RHEL 9
The following components are running on this Linux RHEL 7.9 server:
- IBM Content Navigator 3.0.11
- IBM Content Manager OnDemand 10.5.0.5
- IBM Websphere Application Server 9.0.5.13 ND
Does IBM software (ICN, WAS and CMOD) support in-place OS upgrade from RHEL7.9 to RHEL9 or should we make a new installations on a new Linux RHEL 9 server and make switch-over from old RHEL 7.9 server to new RHEL 9 server?
While I think I understand what you are driving at, what does support mean to you in this case? Ideally, we always recommend new hardware/VMs. It is so much safer of a process. We also never recommend having all these components on the same server. ICN should be separate from the CMOD server.
Thanks for your reply rjrussel,

Good question, I will try to list what I want to know(from top of my mind)
- Is it OK to do so from IBM point of view, or are we performing something here that could lead us "out of support".
- You say you recommend "new hardware/VMs", do you then have any experience where ICN / WebSphere / ODWEK would not function after upgrading the OS?

We have ODWEK only on this server - bit unclear there yes.
CMOD / DB2 running on separate server.
I can't speak for all of IBM - 8) - but it's fine. I'd say our opinion is have a perfect backout strategy if the OS upgrade fails.
ok... This comment:

This led me to believe everything is on the same server.... Sounds like you have a good distribution, so all is well. BTW: I just upgraded a server this week from 7.9 to 8.9. No issues. Your mileage may vary.
