Move server to different OS

[EriSan500]

Hi all,

what steps should i need to take to move a Zimbra installation from a FC3 server to a CentOS4.2 server? (hostname will stay the same, though IP will be different)

Thanks and keep up the great work you're all putting into Zimbra

I don't have the technical background of the Zimbra guys, but if you have the Network Edition you could make a backup and restore it on the new server/platform.

[marcmac]

network is on RHEL4 only, so that's not going to help.

Install the same zimbra version on your centos4 box.
copy everything under /opt/zimbra from the fc3 box to the centos4 box.
RE-install (meaning upgrade) the same zimbra version again.

start everything.

Oops, didn't think on that.

Hi guys,

this is my first attempt to move zimbra from 1 server to another. Allthough i did a zmcontrol stop , service zimbra stop , i get the below errors when copying the /opt/zimbra dir.

Is this something to worry about ?

Thanks in advance

You should probably do some reading on file permissions in linux

[EriSan500]

I solved it by using RSync, worked perfect:

#!/bin/sh

# Simple rsync "driver" script.  (Uses SSH as the transport layer.)
# http://www.scrounge.org/linux/rsync.html

# Demonstrates how to use rsync to back up a directory tree from a local
# machine to a remote machine.  Then re-run the script, as needed, to keep
# the two machines "in sync."  It only copies new or changed files and ignores
# identical files.

# Destination host machine name
DEST="your.destination.ip.address"

# User that rsync will connect as
# Are you sure that you want to run as root, though?
USER="root"

# Directory to copy from on the source machine.
BACKDIR="/opt/zimbra/"

# Directory to copy to on the destination machine.
DESTDIR="/opt/zimbra/"

# excludes file - Contains wildcard patterns of files to exclude.
# i.e., *~, *.bak, etc.  One "pattern" per line.
# You must create this file.
# EXCLUDES=/root/bin/excludes

# Options.
# -n Don't do any copying, but display what rsync *would* copy. For testing.
# -a Archive. Mainly propogate file permissions, ownership, timestamp, etc.
# -u Update. Don't copy file if file on destination is newer.
# -v Verbose -vv More verbose. -vvv Even more verbose.
# See man rsync for other options.

# For testing.  Only displays what rsync *would* do and does no actual copying.
#OPTS="-n -vv -u -a --rsh=ssh --exclude-from=$EXCLUDES --stats --progress"
# Does copy, but still gives a verbose display of what it is doing
OPTS="-v -u -a --rsh=ssh --exclude-from=$EXCLUDES --stats"
# Copies and does no display at all.
#OPTS="--archive --update --rsh=ssh --exclude-from=$EXCLUDES --quiet"

# May be needed if run by cron?
export PATH=$PATH:/bin:/usr/bin:/usr/local/bin

# Only run rsync if $DEST responds.
VAR=`ping -s 1 -c 1 $DEST > /dev/null; echo $?`
if [ $VAR -eq 0 ]; then
    rsync $OPTS $BACKDIR $USER@$DEST:$DESTDIR
else
    echo "Cannot connect to $DEST."
fi
