Upgrade of linux Offsite via ssh. Is it possible??

Guys!!

Is it possible to upgrade from RedHat 6.1 to 6.2 on the fly via ssh. Has anyone come across a situation like this.

I may be awarded a contract from a company to upgrade their server since their tech support guy is on vacation. I've only upgraded linux onsite. However I don't want to refuse this offsite upgradation unless I am absolutely sure that it is impossible. Any links to relevant sites will also be appreciated.

Any ideas anyone !!
