Migrate Linux Qmail to Exchange 2010 RRS feed

  • Question

  • Dear sir,

         Customer is using Linux Qmail for many years with 500 users, there are 2 type of client. 

    - Client with Outlook using IMAP connection to Qmail

    - Branch workstation client are only using web browser for managing inbox and their own created folders.

        Now they want to migrate all user from Qmail to Exchange 2010. I understand that Microsoft Transport Suite can work for IMAP migration, but it is not for Exchagne 2010.  So in microsoft direction, do the only possible action is:

    1. Use Outlook to connection connect client with IMAP connection

    2. Dowload all email into PST

    3. Import back to user database.

    As it is very time consulting to perform each mailbox manually one by one. Any others automatic method?

  • Hi Joe,

    AFAIK it's not possible to migrate calendar data with IMAPsync cause of IMAP limitiations. Calendar sync often works with protocols like iCal, so it isn't "synced" with IMAP.

    Regards,

    Chris

  • Hi,

    I would use IMAPSYNC to perform this.

    There is a good HOWTO-Manual which describes the necessary steps.

    Regards,

    Chris

  • You can use the Transporter Suite, but that requires introducing a temporary Exchange 2007 server so that's a bit too much perhaps. You could use tools like imapsync, which also gives you the option to script the synchronisation process for a user set. Also, you could already set it up and do an initial load of the mailboxes before doing the actual migration (without deleting the original mail, but I suspect it doesn't handle deletions at the source) and finally perform the real migration.

    Regarding the amount of work, removing the IMAP account from all those profiles may also require some work. Also, are they already using a PST for calendaring etc? If so, it may be required to merge that information as well.

  • Dear Christopher, Tolixxxxx,

       Thank you for your suggstion of IMAPSync, I have tested it. It is very great utiltiy. I use it with tee utility, every console screen can show during synchronization and output.

    It works fine.  But 1 more question, is it possible to migrate if it has calendar ? Or it just work for mail?

    Thanks,

    Joe
