Ah, makes sense.
You should be able to export the email templates via the retrieve email template API and them re-import them using the same API. It may take a bit of fiddling, but it should be possible. In fact, you may want to capture the email templates as a kickstart file for future deployment/dev envt setup ease: https://fusionauth.io/docs/v1/tech/installation-guide/kickstart
I think we already have some issues about configuration migration, so you may want to check them out and vote for them if they convey what you'd like (please upvote them if so):
