1. Email Data Migration

Email data migration steps

Please perform the following steps.

*The steps in 1-3 and 1-4 require the Thunderbird or Becky! Ver. 2 email software.
Thunderbird can be used in both Windows and Mac, while Becky! Ver. 2 is only available for Windows.

  1. 1-1. Organizing sent emails

    Organize the sent emails.


  2. 1-2. Reflect the sorting, read, and unread statuses of emails to the new system.

    The sorting, read, and unread statuses of emails from September to the present will not have been reflected in the new system (Gmail), so these should be reflected.
    (Emails remain in the Inbox unread in the new system (Gmail).)


  3. 1-3. Migrate emails that could not be automatically migrated

    Emails that exceed the 25MB per email limit and emails with attachments where the extension is an executable (such as .exe, .bin, or .sh) cannot be automatically migrated.
    If there are any vital emails in there, check the steps and then migrate them.


  4. 1-4. Migration of emails in Drafts
    Migrate emails in Drafts from September to the present.
    If there are any vital emails in there, check the steps and then migrate them.

To continue the migration process, follow the migration process site map.
