    Default OSS 32-bit to 64-bit migration

    My current setup --

    CentOS 5.2 32-bit
    ZCS OSS 5.0.6

    My desired setup --

    CentOS 5.4 64-bit
    ZCS OSS 6.0.5

    First of all, I can't find any OSS method for going from 32-bit to 64-bit. Is there any way to upgrade from 32-bit to 64-bit directly for OSS? I don't think upgrading from 5.0.6 to 6.0.5 would be much of a problem otherwise.

    If there's no direct upgrade path from 32-bit to 64-bit, what are my options for maybe migrating all my users to a new server, considering a 5.0.6 source server (no zmztozmig, no zmmailbox exports) and my desire to keep accounts (address, name, password, forwards, aliases, distribution lists), email (read/unread, tags, folder structure), calendar, contacts, mail filters, etc.? I don't particularly care about tasks, documents, briefcase, or share permissions.

    I'm planning a similar migration myself. I posted about my plans a few days ago, looking for a little guidance, but haven't gotten any responses yet.

    Although the title specifically references "Network Edition", my understanding from info I've found in past posts is that procedures in the wiki page Network Edition: Moving from 32-bit to 64-bit should work for OSS editions as well (minus the NE specific parts obviously).

    One thing you will almost certainly need to do is to make sure you are using the same version of Zimbra on both systems. So you would either upgrade your existing 32-bit installation to version 6 and then work on your migration to the 64-bit server, or migrate to 64-bit with your current version (5.0.6) and then work on the upgrade to version 6 after you're up and running under 64-bit. For the level you are at with version 5 I think there might be a recommended intermediate upgrade step [ie 5.0.6 --> 5.0.21 (or latest) --> 6.0.5 (or latest)].

    Hope this helps.

    Thanks for that link soxfan.

    I'm looking to go from 5.0.11 on Fedora 7 x86 to 6.0.5 on Fedora 11 x86_64.

    I've already upgraded the 32bit version to 6.0.5, now I just need to figure out the process for the 6.0.5 32bit to 6.0.5 64bit conversion/switchover.

    I'll check that wiki page out and see what I can do. I'll try and report back how I went.
