How can i backup my Lemmy account for transferring it to other instances

Hello guys so what is your Recommend method for backup and transferring Lemmy account data for other instances

You can't, but there's a github issue to enable this functionality: https://github.com/LemmyNet/lemmy/issues/1985

FYI someone made a script to copy user account communities from one instance to another : https://sh.itjust.works/post/168439

I'm not entirely sure if that's possible right now. There are many requests on the github page for such a feature, but the devs have understandably other priorities.
