301 redirection question

I have done redirection from an expired domain to my niche site (home to home/domain to domain )

I have another expired domain with some content with backlink profile. I want to 301 the old expired domain pages URL to URL of pages on niche site. and redirect all the 404 pages to expired domain home page. I'm going to both with plugin.
but my question is, what should i do next?
redirect Homepage of expired domain to niche site home page? because i haven't redirected expired domain home page to my niche site home page.

finally fixed it
