I have tried this multiple times always with the same result. I was not able to identify any useful logs on either the M-Files server or the SQL server. My current attempt has been sitting on step 7 of the migration process for over 48 hours. I am on M-Files version 23.12.13247.4 and SQL server 2019. If I create a test document vault I am able to perform the migration without issue. I have tried to use SSMS on the target SQL server to verify whether progress is being made and I can see that some information was successfully moved to the new DB. There is an INSERT process to 1 locked table called OVPVPBUILTINH that has been running since I started the migration. I can see that the process is using cpu time but because the table is locked I can't see whether I am making any progress.
If someone could help me with some troubleshooting options, I would be truly grateful.
