You cannot just copy the application(PT) over and expect it to work. There are a lot of other system files that get installed with the installation of the program. You will need to run an installer to do this properly. If you still have your serials for PT, mabye an upgrade email, etc... you should be able to re-download the installer. You might have to wait for a while for it to download on a slow connection, but oh well. A lot of plug-ins can be copied from your plug-in folder, to the new machine, and those that use the iLok for authorization, will work automatically. Those plugs that don't use the iLok, will need to be re-authorized via serial numbers etc... Keeping track of serial numbers, user names etc... is a PITA, but neccessary.

I hope this answered your questions.
Peace
