I am planing to migrate the server currently with 700 + users.
The mailboxes data is stored on the SAN, and the SAN slice is mounted by the machine, using the NFS file system.The current Server OS is Solaris on SPARC machine.
I had deployed the network edition of zimbra on REDHAT Linux 5.
I will also try to deploy the open source zimbra(free/no license) on redhat and on solaris.
Please recommend please the OS & Machines.
