Restore the Zimbra Collaboration Server
If a complete machine failure occurs, use the following steps to restore to a new server.
Important: The ZCS version you install on the new server must be the same version as installed on the old server. The server can have a different operating system.
The new server hardware must meet the requirements described in the Installation Prerequisites section of the VMware Zimbra Collaboration Server Single Server Installation guide. Install the new operating system, making any necessary OS configuration modifications as described in the installation guide.
