It is certainly better to upgrade with less things running as a general

One should never update from a Remote X type connection via VNC or NX, etc.

The absolute safest way to upgrade would be to do so via the console and
a keyboard on the actual machine if there is some issue with sshd, etc.

But generally, this upgrade should be OK via ssh, etc.
