I don't see any problem with that. To be honest most players have played on more then 1 even 2 server. Myself started on S10(For get the name but they taught me the basics then I moved to S38, which was the new server at the time.)--> S38(LionsDen #1)-->S127(TaZTaX #1).

With quick stop on a friends account in S77(Kilowatt #1).
