    It's the same answer as your other (duplicate) post, details on how to upgrade are in the product Release Notes for each version of ZCS. read the release notes in detail then do a backup of your server (details on backup/restore are in the forums and wiki) and run the update.
    Regards

    Are you sure?
    If i'm running Centos 5.8, how can i do upgrade to ZSC OSE 8, when only CentoS 6 is supported.
    In release notes i didn't find any help.

    You'll have to move your ZCS install to a new server with a supported operating system.

    Then you should follow one of the many articles in the forums or wiki on moving your install to a new server.

    There are plenty of answer to your question in the forums and wiki, believe me, these questions have been asked and answered many times.

    Is there something wrong with the search function? site:zimbra.com +move +"new server" - Yahoo! Search Results Go to the first page of the wiki and look at the list of backup/restore articles that's available there.

    I haven't seen an official article on migrating from CentOS 5 to 6, but the article on going from any platform 32 bit to 64 bit is what I used to go from CentOS4-32 to CentOS6-64:
    Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki

    Just do the following:
    - Install CentOS 6 on your new machine
    - Download the SAME version of ZCS you're running now compiled for CentOS 6 and follow the guide as closely as possible.
    - After you're up and running on CentOS6 with ZCS7.x, run the 8.0 upgrade as normal via the included installer.
