    Default Upgrade path from 5.0.16 to 7.1.4 also change distro flavour.

    Hi,

    The small business I'm working for is looking to upgrade their Zimbra server from 5.0.16 to 7.1.4. At the same time the server's Linux flavor will be changing from CentOS 5.2 to Debian Breezy.

    #zmcontrol -v
    Release 5.0.16_GA_2921.RHEL5_20090429052155 CentOS5 FOSS edition


    In broad terms how should I best approach this upgrade? Should I do a number of incremental upgrades or should I jump directly from 5.0.16 to 7.1.4?

    What tools / techniques should I employ.

    The new Debian server will be virtual so I have the opportunity to test the upgrade cycle.

    Your help will be greatly appreciated.

    Thanks

    John

    This has been covered many times in the forums and there's even a couple of wiki articles on the subject.

    Read the Release Notes in detail to see which version you can upgrade from, incremental upgrades are never necessary unless stated in the Release Notes. Next, read the Certified wiki article on move a server from one server to another (plkus 32bit to 64bit, I'm assuming that's what you're doing as 32 bit versions of Zimbra are deprecated) and changing operating systems (there's only one article on this subject that's Zimbra certified, it's an NE document but also applies to the OSS version by omitting the NE steps.
    Regards
