Success criteria for completing a server migration event consists of the server being fully available on the target NAS system and removed from the source NAS system, all cleanup and post-migration work completed such that the server is no longer connected to or has access to the source NAS system.
Provide Day one early coverage after the cut-over to ensure there are no issues when majority of the users login after the cut-over.
After the cut-over old CIFS/NFS access should be restricted and ensure old volumes are offline for 2 weeks before they are destroyed.
Update NAS Volume Contact Database with new volumes and contact SA
Must engage business/SA teams to provide migration checkout and signoff.
Perform the steps necessary such that volumes have been fully decommissioned, all user and share association deleted so that the appropriate hardware vendor can complete decommission and scrubbing of old volumes and remove hardware from service.
