Last step is to uninstall to old qlik service.
But in your case I understand you want to proceed in another way, meaning install Qlik Sense from scratch in another server and then restore the Postgres DBs backup in this new server.
In that case the step you mentionned (Finalizing the upgrad/uninstalling the old DB service) is to be ignored. This step is only when after you have upgraded the Qlik Sense Postgres version from 9.6 to 12 (Using QPI) and when you are upgrading this Qlik Sense version to a new version.
So your steps would be like that:
Migrating from current version to the same version in new server (May 2022 P2)
What does this means exactly? After restoring the back-up in my new server, in version May 2022 P2, if I want to upgrade this to Feb 2023 version, then I have to perform this step? Does this apply if I want to upgrade from May 2022 P2 to May 2022 P3?
After changing host name, I got some issue to access QMC and Hub address of Qliksense, then I uninstall and re-install Qliksense server after backup C:\ProgramData\Qlik\Sense\Apps folder.How can I restore all apps in that folder to new server Qliksense? Files in this folders is not *.qvf, then I cannot import them via QMC, I tried to copy them to new C:\ProgramData\Qlik\Sense\Apps folder, but it didn't work.
