HA or FT for server maintenance?

I'm spinning up a new print server in our VMWare / ESXi 5.5 environment.

I'd sure like to be able to take it offline for maintenance (service pack updates, microsoft updates, etc.) without keeping the entire company from being able to print.

I have HA enabled on the cluster and setup fault tolerance logging on our vmotion network. I can enable FT on a test VM.

So how to I "failover" to the secondary VM and log into the primary to do updates? I would then need to return to using the primary. And push the changes to the secondary.

Also, as an aside, I had to do all this work in the fat client. My primary and secondary vm's show up in the fat client, but not in the web client. 

Thanks!
