The following warning is shown during a Migration:
Insufficient disk space on the destination server to transfer all the selected subscriptions. Available: 14753 MB. Required: 235603 MB. Note that the required space is calculated as a sum of web, mail, and database contents of domains. The required space is calculated once a day and stored in cache, so the actual size of domains might differ from the calculated size. If you make sure that the selected domains do not occupy more space than available, you can proceed with transfer.
