My SQL Server 2012 DR setup is a mess. We've had a maintenance plan in place from the beginning that takes a daily full backup, with hourly log backups. Recently, we set up log shipping to an off-site server and it seemed to be working great. The LSBackup job runs every 15 minutes.
I know that I need to change my maintenance plan to Full + Differential, but my question is do I need to remove all log shipping, restore the secondary database from the most recent full backup and then set up log shipping again?
Or, can I pause the LS jobs, to the restore and then restart the LS jobs?
Or, is the secondary server fine an I just need to fix my maintenance plan?
