Copying Plug-ins

I have PT 10. It was running on a Macbook pro. I recently purchased a Mac Pro. Every thing seems to work except the Plug-ins. Some of them don't. One is Xpand 2. I can't get any instruments. I guess there's some file I did not copy. I'll probably have the same problem with some others. I haven't gotten that far yet. Can someone help?
The folders I copied are:
Mac drive/Library/Application Support/Digidesign/Plug-Ins

Mac drive/Library/Application Support/Digidesign/Plug-In Settings
