It’s been about 3 1/2 months since I made the switch to Source Gear Vault as my primary home source control. In the time that I’ve been using it it has performed superbly. I recently did an upgrade, simple, quick and painless. All totaled it took probably ten minutes to upgrade the server using a single setup executable. Contrast that to the day it took a co-worker to upgrade subversion and the fact that he had to compile the new server GUI functionality and it quickly becomes apparent that subversion is more of a road block than an asset.
A couple of weeks ago I ran across this Source Control How To by Eric Sink, one of the Source Gear Co-Founders. Even if you’re a source control expert it’s a good read.
