I will have to migrate our current ZCS 6.0.7 32bit in Ubuntu 8.04 server from virtual environment to a physical quad core server with 4GB of RAM. In this case I would use Ubuntu Server 10.04 64bit as my OS for the new machine.
My plan is to copy the /opt/Zimbra folder from the old 32bit Ubuntu 8.04 server to the new 64bit Ubuntu 10.04 server then run the 64bit version of ZCS 6.0.7. Is this possible? If not, could you guide me to the steps I need?
