How to change the niche of a running account


I currently have 7 aged accounts running full speed on a niche test that turns out to be not profitable enough. Now I want to add them to my main niche (the most satured but stable niche). How should I do this? First let them rest for a day, then change name/bio/link and then start again?


Here’s what I do. I stop all tools except for unfollow & delete posts. I let those run until all my previous posts are deleted. I wait a day & then rebrand the account. Wait another day or two & start the other tools again.
