How to upgrade the Linux based vCenter Server ?

Hi All,

I am using the  Linux(VM) based vCenter server 5.0.  Now I need to upgrade to the vCenter server 5.1. How do I take a backup and restore the data on new server. New vCenter server 5.1 is also a Linux based VM.

When I search for the upgrade document I can find for Windows based vCenter server and not for the Linux based one.

Could you please guide me in how to upgrade the vCenter server.

Thanks,

Kalai
