hi,
in additino to what tristaanogre said, if you want to start 2 project suites in parrallel I assume you have to licences of TestExecute.
a tip : you can launch the 2 projects suites but you won't be able to work on them simultaneously with TestComplete.
So for night runs, it could be the same projects suite, but for the day, make copies and use VM such as HyperV on your local machine...
Yup, what m_essaid said...
You can achieve basically the same effect using a source control tool like Git or Mercurial. Check out the solution presented here. In your case, you would have your dev machine and your two running environment machines. As mentioned, this requires licenses... most likely a single license of TestComplete and a couple of TestExecute licenses.
