At this moment no transfers are available for SOD at all.
Generally (free) realm transfers are only given from high to low population. They are also not enabled if ever, for locked realms/factions.
Which is something they announced in advance:
Nobody forces you to play this game. Or what “bad servers are”. In fact, if the playerbase didn’t designate several realms as the Designated Realm to Play On it may as well have been reversed realm names but same situation.
