I was looking for an answer to this and couldn't find anything but heres my problem: I am currently a subscriber and my subscription is gonna end in a couple days and I was wondering, what happens to my 9 characters? Do they get deleted? Do they get moved to another server? And what of their high level gear?
Here's a link to the F2P FAQ and it has answers to your questions. For some odd reason, they don't have this link on most of their F2P pages and it's pretty hard to track down now: http://www.swtor.com/support/helpcenter/6449
