dzfplanning - I took one final step to fully transfer the domain to zoosysop, so that the old user account, dzfplanning, will no longer be able to have access to the domain manager.
You will still need to log into the domain manager to update your contact details - this is important so that the email, registrant name, and other information connected with the domain stays accurate and up-to-date. If this info is not correct it can cause problems in the future.
auxclass - in general transferring upgrades between users requires staff intervention. Building in a facility for folks to do this on their own may be something we look at in the future but I don't have an ETA. :-)
