Adamantoise is a preferred world? Then yes perhaps the restriction might still be there if coming from Balmung, but I have not checked the current status in some time as never really needed to so that's something OP should look at.

You could try to do the transfer via Mog Station and see if the restriction message shows up (nothing with be charged if so) but otherwise I'd just wait the remaining 30days and do the transfer after that. You'll still be able to do cross party stuff with your friends on Jenova though.
