Server First Class/Profs

Are there the same guidelines for this as there are titles and other feats of strength? Do you have to be on the server more then 60 days in advance?

More specifically, would transferring any characters at this time jeopardize that possibility? I am only speaking on leveling achievements, not raiding. If I wanted to play with friends who are on a medium pop server would I still be eligible?

Thanks in advance
