Can I connect to the DB with old QS version?

[aihua]

I have a standalone QS DB . And I upgrade QS from Nov 2022 to Nov 2023. 

What if I connect to this standalone DB with QS Nov 2022 version？

Hi, 

I don't think it's a good idea:
When you perform an upgrade, the schemas and tables of the Repository Database changes. 

What's the point beyond this question ? You want to revert to Nov. 2022 ?

Hello, @aihua 

A revert from a newer database of Qlik Sense Client Managed version to a older one is not supported. So if you still have a old Backup done with the November 2022 version you can restore that one. With the other one you will fail running the bootstrap command due to the version missmatch.

best regards
