    Hello,

    If your intention is to migrate from the FreeBSD server to the Ubuntu server, you have the following approaches:

    1) Relying on Axigen's Automatic Migration functionality
    2) Copying the Axigen working directory to the new server.


    1) The Automatic Migration is the safest approach and does not involve any service downtime. The disadvantages are that you need to keep both servers online during the migration, and that it will be slower than the second approach. Also, this approach copies user data such as emails, calendar items etc but not the server's/user's configuration or user filters. Also, because messages that were sent to multiple local recipients would be copied to the mailbox of each user, and therefore the disk usage would be a bit higherThis approach is detailed in our online KB article at:
    http://www.axigen.com/kb/show/203


    2) Directly copying the Axigen working directory to the new server. This approach is faster and copies all data, however during the copy operation, the Axigen service must be in a stopped state on both machines - which means that you can not avoid a service downtime period. The required steps are presented below:
    - install on the Ubuntu server exactly the same Axigen Mail Server version as the one installed on the FreeBSD server
    - do not start the axigen services on the Ubuntu server
    - stop the axigen services on the FreeBSD server
    - copy the Axigen working directory, /var/axigen , from the FreeBSD server to the working directory ( /var/opt/axigen) on the Ubuntu server
    - Edit the Axigen configuration on the Ubuntu server with the new file paths (all paths containing /var/axigen to be replaced with the Ubuntu paths - by default /var/opt/axigen))
    - start the axigen service on the Ubuntu server

    Please keep us updated in this matter.

    Thank you.

    Best regards,
    Bogdan Maxim
