Server Move to same platform 32-64bit and OS type & version

Assumptions

New server is setup with the same HOSTNAME information as PROD but it will use a different IP until PROD can be shutoff/reconfigured (if needed)

Preparing NEWHOST Server

1. Install Newer (supported) Operating System that matches PROD

2. Set up newer ZCS Server’s Hostname as it was on the older server

3. Configure BIND locally on NEWHOST to handle resolution issues (A, MX, etc.)

A. On NEWHOST confirm /etc/hosts , /etc/resolv.conf

4. Download EXACT version that your PROD is using.

A. http://www.zimbra.com/products/downloads.html

B. http://www.zimbra.com/products/downloads_previous.html

5. On NEWHOST as ROOT: Run the installer with the -s option:

./install.sh -s

6. On NEWHOST as Root: Remove the dummy install:

rm -rf /opt/zimbra

A. This tells the installer to only install the software, and not to configure the installation.

Sync PROD Data While PROD Is Still In Production Use

1. First initial sync of PROD to NEWHOST

A. on PROD as Root

nice +19 rsync -avz -e ssh --progress /opt/zimbra/ root@NEWHOSTIP:/opt/zimbra

2. Sync daily until schedule downtime is available

A. On PROD as Root

nice +19 rsync -avz -e ssh --progress /opt/zimbra/ root@NEWHOSTIP:/opt/zimbra

The Big Day - PROD Downtime For Switch

1. Shut down Zimbra on PROD

A. On PROD as ZIMBRA

su - zimbra
zmcontrol stop

2. Last rsync of PROD to NEWHOST

A. On Prod as ROOT

nice -20 rsync -avz -e ssh --delete --progress /opt/zimbra/ root@NEWHOSTIP:/opt/zimbra

 3. Fix permissions on NEWHOST

A. On NEWHOST as ROOT

run zmfixperms located in /opt/zimbra/libexec

4. Install of Zimbra on NEWHOST

A. On NEWHOST as ROOT, rerun the installer without the -s option

./install

B. It will detect ZCS already installed, and ask if you want to upgrade. Select Yes.
