There shouldn't be any need to spend your LoveCa stones before transferring account, as that would only be for transfers between Android and iOS.

Doing a factory reset is likely to erase your app data entirely, so it would be best to request a transfer code before proceeding. Please refer to the instructions on this thread on how to do so.

If you're playing on the JP server and already on V2.3, there should theoretically not be any problems as your save-game is tied to Google+, but it would still be wiser to play safe and request a transfer code first.
