Notes

The discussion mailing address format in CEE is forumalias@project.domain whereas in CTF 6.0 it is forumalias-project@domain.
Note: Post-migration, the response emails to the existing CEE mailing address will be re-directed to the new CTF 6.0 mailing address and captured into appropriate mailing lists. However, it’s recommended to use the new CTF 6.0 mailing address for any new posts. The future releases of CTF 6.0 may not continue supporting the old mailing address compatibility.

Tip: A CEE forum list name can start with a number or "_" and can also have "." and "-" characters, whereas, CTF 6.0 imposes certain naming conventions. So, if the toAddressUsername (list name) in CEE contains "." or "-", it is replaced with "_" in CTF 6.0. If it starts with "_" in CEE, the underscore is removed in CTF 6.0. If it starts with a number, post-migration, the number is replaced with the number in word, suffixed by an underscore. For example, "1team" mailing list address becomes "one_team" post-migration.
The posts made by guest users in CEE are migrated with their actual mail-ids being prefixed in their messages.
The Default Discussions feature is not available in CTF 6.0. The different default discussions (Issues/Commits) serve as archives for any change to issues/version control commits. These are migrated to CTF 6.0 but post-migration, these forums do not continue as archives.
Any form (approved/un-approved) of soft-deleted posts/topics/forums is not migrated to CTF 6.0 as CTF 6.0 does not have soft deletion feature.
The CJK filenames are not preserved.
Subject Prefix and Footer text fields available in CEE's create page are mapped in CTF 6.0's edit page.
Email messages can not be blocked based on attachments in CTF 6.0.
In CEE, "Content in email" has two options: Send full text of posted messages and send email notification with link only. In CTF 6.0, send full text is the default email content behavior
In CEE, "Email notifications" has three options: Message-by-message, digest format and start page only. The discussion subscribers in CEE with 'Message-by-Message', 'Digest Format' and 'Start Page Only' are migrated as 'Email per Change', 'Daily Digest Email' and 'Don't Send Email' respectively.
In CEE, there is no character length restriction on "Topic Title", whereas, in CTF 6.0, it is restricted to 250 characters.
In CEE, subscription is allowed at the discussion level whereas in CTF 6.0, it is allowed even at the thread level.
CEE features that are not available in CTF 6.0 include: Default Discussions, Message size, Message Header, Soft deletion, Guest Posting, User Groups, Anonymous and Sub-list subscribers, Email Subscription, Other Recipients, Web Post CAPTCHA, Remove deleted messages and Remove unmoderated messages.
CEE's "Reply Behavior" is mapped appropriately. Discussions with 'Reply to list', ' Reply to Sender', 'Reply to entered email' and 'No reply-to' are migrated to CTF with 'Reply to the list', 'Reply to sender', 'Reply to a different email' and 'Do not add a reply' as corresponding settings.
CTF 6.0 does not support CEE's advanced email filter options like mime types, headers, reject content.
In CTF 6.0, based on the user's permissions, web UI and/or web posting can be accessed.
By default, forum mailing list is displayed in CTF 6.0 as the display email address.
