Observation when updating to version 9.2.2

Hello,

We are in the process of upgrading our environments from Version 9.0 LTS to version 9.2.2.

We would also like to use new servers for this - from WinServer 2019 & MSSQL 2019 to new WinServer 2022 & MSSQL 2022. 
We are currently in the development environment and are making the following observation - the operation “QBM-K-BaseMigrationReady” has been in processing for almost 24 hours.

No blockage or similar problems can be detected on the SQL server.
When looking at the dialog journal, messages like this appear:

50000 0 #LDS#No job started for more then {0} s (detected in {1} loop).|      2401|inner|  50000 0 detected in  (SRV=<db-server>, DB=<DB-Name>) procedure QBM_PWorkDBQueueMain Line 050000 0 logged in DBQueue Processor  


Are there others who have made similar observations?
Or in other words - which places should we check?
Many thanks for any information.

Kind regards
