As MERLIN transitions to a standalone cluster in MOBIUS, we will be migrating to the III-hosted environment for Sierra. The date planned for this migration is March 30, 2017. During the migration, which is scheduled to take anywhere from 4-6 hours starting at 8am PST, the MERLIN catalog will be unavailable. You will not be able to access Sierra for staff purposes nor will the MERLIN OPAC be available to the public. Please plan accordingly and if you have any questions, contact your MERLIN Standalone TF member (David Owens, Maggie Trish, Buddy Pennington, or Corrie Hutchinson).
