SQL Server Log Shipping for Server Migration - What's the final step?
You need to remove the log shipping metadata. The correct way to do this is via stored procedures, which also removes the jobs (I'm guessing you've deleted those manually).


Execute sp_delete_log_shipping_secondary_primary. This removes the information about the old primaries on the secondary server (Server A). Also removes the jobs if they exist.
Execute sp_delete_log_shipping_secondary_database. This removes the information about the secondary database. NOTE: This does not remove the DB itself, even though the documentation wording makes it sound like it might. Also, this should be called as part of step 1's stored proc, however, I've found that with orphaned log shipping configs, sometimes it doesn't execute so I run it manually afterwards.
