As of May 1, 2023, Adobe will start migrating Acrobat users to a unified Adobe cloud storage. No action is required by users for this migration, and Adobe is working to minimize disruptions during the process.

Migrations will happen when Acrobat is not in use by users; however, if a user does take an action during the migration, they may receive an error message.
