I am planning on migration all users to a new database on the same partition.
Once migrated, the old DB will have lots of white space. When performing offline defrag on the old database, will I still need double the free disk size on the volume?
I want to try not to delete the database in the long run and rotate databases for production mailbox moves.
DB1 - current
DB2 - current
DB3 - empty - ready for migration
