    Default [SOLVED] ZCS 5.02 - 32bit to 64bit RHEL

    So I would like to move a 32 bit ZCS 5.02 to 64bit. I am running RHEL. I know the directions at Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki are applicable to the 4 series, but what are the changes for the 5 series? What about SSL certificates?

    I did the 32 -> 64 move on a 5.x.

    It went nicely (the thing you have to worry about is the LDAP dump, then you can rsync all /opt/zimbra from one server to the other).

    The certificate (GoDaddy SSL) was not a problem at all.

    By your description, it sounds like you didn't follow the wiki article I referred to, what steps did you use. The wiki article suggests only syncing /opt/zimbra/data/*, /opt/zimbra/store/*, and /opt/zimbra/index/*

    The wiki article is for 4.5.X.

    From what I remember, I did :
    • setup new server with 64 bits OS
    • setup a dummy install of ZCS 64bits on new server (same release than old server)
    • rm -rf /opt/zimbra/ldap-data on new server
    • dump LDAP data to ldif file on old server (see wiki)
    • stop ZCS on both servers
    • import LDAP data from ldif file on new server (see wiki)
    • on new server, copy /opt/zimbra/openldap-data to a safe place (outside of /opt/zimbra)
    • rsync /opt/zimbra from old server to new server
    • shut down old server
    • on new server copy /opt/zimbra/openldap-data from safe place to standard place
    • "upgrade" ZCS to ZCS 64bits on new server (same release, run "./install.sh -s")


    I read all I could find on the subject and the best info I got were John's posts in this thread : Problem With Moving ZCS to New Server

    I don't remember exactly when/how I stopped ZCS on the two servers (and halted the old server). I remember you have to be carefull with your hosts file in new server (as usual) or you can not import ldif data.

    Migration complete. I had a small issue related to uid/gid differences between the two servers, once I saw that, the migration went like a charm. Thanks!

    Cool. I did a fun migration yesterday from 4.5.5 PPC NE to 5.0.5 x86 NE.

    Boy was that fun....
