    Default 5.21 OSE > 6.08 NE Migration Question(s)

    Currently I am running Zimbra 5.21 OSE on CentOS 5.5 32bit.

    We are planning on moving to Zimbra NE 6.08 on RHEL 5.5 64bit.

    What is the best way to approach this? I have 2 scenarios in my head.

    Apparently I have to run the NE installer to "upgrade" and have it recognize the license file. I figure since I am doing an "upgrade" script, I may as well run the upgrade for 5.21 > 6.08.

    Scenario 1:
    CentOS 32bit Machine:
    Run 6.08 NE installer on my 5.21 installation. This would recognize the license file as well as upgrade my installation. Kill 2 birds with 1 stone.
    Then migrate to 64bit after this following this guide:
    Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki

    Question: If I do go with this scenario, we do not currently use LDAP with zimbra. Should I just skip all ldap steps in the guide, or follow them regardless? Also, can you setup LDAP later or only durring install?

    Scenario II:
    CentOS 32bit Machine:
    Run 5.21 NE installer to "upgrade" which will turn it to NE version instead of OSE.
    Run 6.08 NE installer to upgrade from 5.21 NE to 6.08 NE
    Then migrate to 64bit.

    Thank you for your time.

    You do use the Zimbra LDAP, for a start all the users are provisioned in there so you should not miss the steps relating to LDAP.

    Oh I was under the impression it was just to tie into something like Microsoft AD. Thanks for that phoenix. What about the rest, any suggestion on which route to take?

    Take a backup of your /opt/zimbra directory then upgrade to the current OSS version and make sure it's working OK, when that's done I'd suggest you block inbound mail at your firewall and upgrade to the NE version(just in case there's a problem) then backup the NE version using the inbuilt backup procedure. You can then follow the wiki migration article. Having said that, either scenario you describe should work.
