Migrating SBS Starter Pack to new hardware

I have searched the entire forum and knowledgebase for an answer to this
and haven't found one. I have a very small business client (2 users)
that is currently using SBS 6.5 Starter Pack. I have convinced them to
upgrade to better hardware from a clone tower. My question is can I
migrate the starter pack server without affecting the activation that is
already in place? Or will I have to reactivate after the move? If
reactivation is necessary, can that even still be done since the starter
pack has been discontinued?
