Is Windchill Release: 11.1 M020-CPS24 will work in Linux server with OS version RHEL 8.8+

[RT_12095967]

I am using Windchill PDMLink Release 11.1 and Datecode with CPS M020-CPS24

Hello Team ,
We are currently using Windchill Release: 11.1 M020-CPS24 hosted on Linux server OS version RHEL 7.9.
Now planning to upgrade to 13.0.2.1 version. For that we came to know that Linux OS version need to upgrade to RHEL 8.8+
If we upgrade the Linux Server OS to RHEL 8.8+ whether the existing Source Windchill version 11.1 M020-CPS24 will work ?

I never do an upgrade on my existing production hardware. I have 2 or 3 sets of virtual machines that I use for the upgrade testing and then production upgrade.

Build your 13.0.2.1 system on the RHEL 8.8 and then import the database files, copy the file vaults over and finally run UpgradeManager.  That should give you a clean running 13.0.2.1 system. 

There are some changes in the usage of the LDAP that came into play at Windchill 12.0.1, so not sure how that will be handled in the upgrademanager. always do a test upgrade before doing the production one. I did a production Windchill 13.0.2.1 upgrade last week from 12.0.2 but on Windows Server 2019.
