    Lightbulb Migration Feature Idea

    Hi

    Your migration system works awesomely, and top marks on that

    Based on my own experience of migrating Zimbra from 6 to 8 from one server to another I did had an idea about a feature that you could add to your migration software though that I think is probably unique (as I cannot find any other service to provide this),

    The idea is in essence is to add more control over the switch over point by adding the ability to synchronise the two systems

    In order to make the process as stress-free as possible on single server installs (at least) would it be possible to add some sort of server-client feature of the zextras migration tool to forward any incomming mail to the "old" server over to the "new" server so as to keep them in sync ready for the switch over.

    If this is possible then it would allow you to build up the new system, check it works fine, then at the migration point shut down the first system and alter internal dns settings to point to the new system (e.g. mail.domain.com now internally resolves to server B not server A)

    I appreciate I may not have conveyed this very coherently, but hopefully you can see where I'm headed with the idea :-)

    Feel free to say "you fool, that won't work" but the idea of being able to control the migration process better by allowing the servers to automatically sync is pretty neat and similar to a process we use in our own web based telemetry system when we migrate customers from server to server whilst maintaining a set of remote outstations

    Hello nixy32!

    Thank you for the suggestion...
    The cauldron in which our R&D and Devs brew their ideas is always bubbling, and looking inside it I can see something very similar to what you suggest...
    But this is still an idea in the magical cauldron, so I can give no detailed information

    Have a nice day,
    Cine

    Excellent, glad I'm not alone in my thinking then

    I was looking back on the migration experience and trying to determine what the most stressful aspect of it was, and the fact that I had to complete it in a set time-scale was pretty much the largest aspect (it took 4 hours to export and then import all the data, not to mention some of the trouble with getting Z8 to play ball during install/post migration) so if we could've had a period of time to run the two systems in some kind of quasi-parallel state that would have have been a huge improvement.

    In this case you can use the ZeXtras Suite trial on both servers to perform an "Incremental Migration" using ZeXtras Backup, the downtime will be near to zero...

    Nonetheless, R&D and the devs are working on something regarding "one click" migrations, stay tuned for more info!

    Have a nice day,
    Cine

    Hi

    Thanks for the reply

    My angle was more that rather than have to do repeated manual export/imports that the two systems would automatically be kept in sync for a period before you decide to "throw the switch" and change horses from one system to the other.
