    Default Migration Question

    So, we are sort of in a bind. Our dedicated provided hosed up one of our servers that we were planning to migrate in the future - and now we are in a pinch.

    We had Zimbra 5.0.18 running a Debian 4. The provider managed to hose up the OS, so they are reinstalling the os - but are installing Debian 5 32bit instead since they no longer do 4.

    We do have file level backups, and also access to the /opt folder from before the hosed the OS.

    My question is - what is my best bet to get everything back online with the least amount of headache? Also - there is roughly 200GB of email for this install also.

    Any tips,trick, comments are greatly appreciated!

    I have been reading through everything I find. The question I have is will there be any issues putting 5.0.18 on a debian 5 server to get the initial install back up?

    That wasn't your original question unless I missed something in your post? The article tells you how to move from one server to another and with a change of operating system, unless your changing architecture from 32bit to 64bit then there should be no problem if you have the /opt/zimbra directory.

    As long as you're not going from 32-bit to 64-bit (or vise versa) it will be a breeze and completely painless. Try to keep the same server hostname if you can. Follow the blog and you should be good.

    Thanks - just waiting for the 200GB of mail to sync up - then we'll see if it works.

    I will be moving to 64bit down the road - but first disaster recovery.

    Question though - is it possible to go from 5 -> 7? Or do I need to do 6 first?

    You can go straight from 5 to 7 no problem, just so long as their are ZCS7 binaries for your OS. The only 32-bit Deb binaries are for Ubuntu 8.04 LTS; none for 10.04 LTS.

    Not sure on which Debian version 10.04 is based, but if it's 5, you'll need to go to 64-bit to get to ZCS7.

    Hope that helps,
    Mark

    It was a headache bringing things back online. Debian etch shipped with perl 5.8 which is needed for ZCS 5.x, but Debian Lenny shipped with perl 5.10

    So just so if others see this - it was most def NOT completely painless.

    At the end of the day the system is up and running on the latest version of ZCS 7, but it was a very rocky road getting there.

    I am sorry you had challenges restoring/upgrading your Zimbra system but glad that it is done.

    FWIW, we caution clients to use only supported operating systems, even when installing the OSS version, if only to avoid time-consuming dependency issues like you had to work through with perl.

    Again, glad you are back up and running!
