Use this forum if you have a relatively general question or comment about a game, Ventrilo, TeamSpeak, or Murmur/Mumble server with us. If you have a server-specific question that might not help out the community, please directly contact us through your control panel instead.
if you do all aspects of the upgrade via the form, ie new subscription and cancelled the old one, it will be done automatically assuming that this is for a Steam based server.
