Reading through all the solutions above, it struck me that there may be another way to switch AC to a new "main" computer. Would it be possible to accomplish this using the "Amazing Synchronizer" program?
For example:
1. Install AC 4.0 on the new "main" computer; during install, select the option that "this computer may be taken off site and sync-ed upon return".
2. Once installed, start up AC on the new computer and connect to the AC database on old "main" computer (I believe this step is necessary to populate AC on a new computer with the practice data). Then log off AC on the new computer.
3. Start up Amazing Synchronizer on the new "main" computer and choose the option to "Sync & take this computer off site". Under "Settings", include the Imported Items in the sync process.
4. After the Amazing Synchronizer finishes, use Amazing Utilities to reset paths on the client computers to the database on the new main computer.
I'm going to give this a try, and I'll report back regarding the results.
