Pre-Migration Check-List

In bMail

In CalMail

  1. Rename any mailboxes whose names contain:
    • the characters: ^ ! %
    • the word "Archive." If you have archived folders in Thunderbird, you will not be able to rename this folder, so transfer mail out of it into another folder
  2. If you have any subfolders inside your Inbox, move them out.
  3. Empty these following folders by June 21:
    • Trash (if you want to keep something, move to another folder)
    • Spam
    • Deleted Items
    • Drafts
  4. Size Quotas:
    1. Combined account sizes of and mail should not exceed 25 GB
    2. No single message and/or attachment should be more than 25 MB
    How to find out your message and account sizes
  5. The following will NOT migrate:
    The following will not migrate properly:
    • Nested folders whose combined names exceed 225 characters. The resulting labels will be truncated.
    • Folders containing no messages (including folders that contain subfolders but no messages in the parent folder). You can fix this fairly easily from the bMail web interface after the migration. More information from the CSS Knowledge Base.
    • If the total number of unique-named folders in BOTH accounts is 500 or greater, you may have to consolidate.
