- Plesk for Windows
- The following error occurs while migrating a subscription:
PLESK_ERROR: Failed to synchronize subscription with plan
Migration tools tried to perform operation in 3 attempts: Plesk error : mbox_quota
- Subscription is assigned to "Default domain" Service Plan on a source server.
- "Default domain" Service Plan exists on a destination server.
- Actual mail usage of migrated subscription is higher than allowed by "Default domain" Service Plan on a destination server.
Service Plans with the same name cannot be migrated.
Go to Service Plans > Default Domain > Resources and change the Mailbox size value to the one that is used on the source server.
