Switching protools from system disk to external hard drive -- need basic instruction

[sberg]

I've been using ProTools LE with an Mbox for a few years, recently got a new computer and installed v. 8.04 on my system disk -- I know, not recommended, and now that the internal hard drive is starting to get crowded I'm seeing why. I've saved up to buy a 2T external hard drive, and will be switching all my recording to that (and upgrading to v. 8.05). Does anybody know of a basic step-by-step instruction for doing this? For example, should I uninstall PT from my computer then reinstall on the hard drive? Or can I just drag and drop the folders? etc. -- I'm not even sure what questions to ask.
