Hello @Ameen,
I received a backup that I somehow managed to restore (with 2.33 and it work), but I don’t really know what was done with the source database.
More information here Retore backup Error : relation "audit" already exists
But yes I also have the impression that an attempt to migrate has been made that it had failed.
I think I’m going to create an empty instance (2.36) and import metadata and data from worked 2.33 instance
