Just upgrade directly to 0.95.1. When you do so, you will need to go to the Armory data folder and delete the folder named "databases" inside of it since 0.95.1 has a completely different and incompatible database format from 0.93.3.
Looks like everything went mostly smooth.... My system hard locked in the middle of the "Scanning Transactions" stage.... It moved to a point where it said 1 sec and was at about 40% or 50% done and the percentage kept increasing for a while until somewhere around 60% the system just quit responding. After rebooting I started Armory back up without having any other applications running and I noticed something.... tracker-miner was going crazy. Probably my greatest annoyance of Ubuntu is that thing..... so a word of advice to anyone on Ubuntu (or other Gnome based Linux that uses tracker)... make sure that either tracker is disabled or is set to ignore your .armory and .bitcoin directories....

The other thing that needs to be said.... be patient.... it takes a long while to go through each step
