its easy, for the prior 3-4 years you can simple save prgram file to a flash drive and move to new machine. once on the new machine you have to find a file for netsetup.exe and that will transfer the registration to your new puter. tech support talked me through the first year and i moved all the prior years. Everything seems to transfer except the manager customizations you might have made.
1 disadvantage is now you have to sign in each time you open the program but thats minor compared to having to reinstall all the years, back-up the clients and reinstall, etc.
