Lemmy.ca is a nice instance. It can be easier for you to manage it from your main account.
I just tried the Piefed migration feature, it's nice, but as said in the other comment, your posts and comments won't show up on the new community on Lemmy, only on Piefed (they would still show up on the old locked community on Lemmy, have a look at this post, it's more clear: https://lemmy.dbzer0.com/post/45876492)
