I am looking at upgrading my vCenter server to Windows 2012 R2, I am doing this as an out of place upgrade, so I have the Windows 2008 R2 machine to fail back onto if I encounter any issues, I will be using the same IP and hostname. Something which crossed my mind is the fact we are not on the latest version of vCenter, I think we are currently on 5.5.0 and the latest version is now 5.5.0u1c.
Our DB is sat on a different server, so when migrating I was going to reinstall vCenter pointing at the database without overwriting, one thing I am unsure about is could I also upgrade vCenter whilst doing this move, so in theory run the latest install of 5.5.0u1c as opposed to 5.5.0 on the new Windows 2012 R2 server?
