    Default Upgraded from zcs-4.5.2 OSS to 5.0.4 Network - No issues!

    We purchased the network version almost 6 months ago. I put off the upgrade due to v5 coming out. I was very nervous about upgrading after seeing people talk about having to dump ldap/mysql and reimporting. I didn't have to do any of that, here is how I upgraded ours. Ours started having problems around 2pm yesterday, a hard drive in the raid was failing and some DNS issues(I think). We had a new asus 1u RS162-E4 w/ 4 gb corsair, dual quad core 5335's, 4 500gb seagate server satas. I plugged in a ext usb hd and did the following on old server.

    fdisk -l to list the usb hard drive
    fdisk /dev/sdc1

    delete any old partitions, and created a new one (primary), w to write and save out.

    mkfs.ext3 /dev/sdc1 (formats partition on usb hd ext3)
    mkdir /migration
    mount /dev/sdc1 /migration
    su zimbra
    zmcontrol stop
    exit (back to root user)
    rsync -avr /opt/zimbra /migration

    3 hours for 81gb of data on 241 accounts

    while it was doing that, We installed centos 4.6, took basic server install, disabled firewall/selinux. We set up the onboard raid using enhanced mirror which is raid 1,0 i think. Centos sees all 4 drives as one partition, took defaults on partitioning. rebooted, did yum update, etc. Unplugged usb hd and plugged it into new server.

    fidsk -l to see where to mount
    mkdir migration
    mount /dev/sdb1 /migration
    screen rsync -avr /migration/zimbra /opt (i screened it off to do other stuff)
    fix ip, hosts, turn off sendmail

    get ready to install zimbra
    yum install compat-libstdc++-296
    mv /opt/zimbra /opt/zimbra_ori
    installed using -s option (no config)
    rm -rf /opt/zimbra
    mv /opt/zimbra_ori /opt/zimbra
    /opt/zimbra/libexec/zmfixperms
    install zcs-4.5.2_GA_699
    made sure everything is back to normal and working

    upgrade to zcs-4.5.11_GA_1751.RHEL4
    ./install.sh --platform-override (since we are using centos)

    yum install libtool-libs
    upgrade to zcs-5.0.4_GA_2101.RHEL4.20080321155827
    ./install.sh --platform-override

    upgrade to zcs-NETWORK-5.0.4_GA_2101.RHEL4
    ./install.sh --platform-override (come on zimbra, centos aint that bad!! -lol)
    use web admin to install lic file in proper place.

    the next day out of 241 accounts, had 3-4 calls mostly about new features.

    I used this as my main guide

    Thanks Zimbra!

    only 1 minor issue, for some reason zimbra will not auto start at bootup, have to su zimbra and zmcontrol start...any ideas?

    Too bad you're using an unsupported OS 8-§

    was already 2345'd. I changed it and did it back again, still no love.

    and as to centos, maybe next upgrade, we'll try ubuntu 8.4 LTS (?)

    It regretted doing our recent migration to 6.06 knowing that they will come out with a new supported version soon - but we were in need of an upgrade..
