Simply moving content from domain A to B and I am seeing rankings being restored.

This year, I got an algorithm hit (the site tanked in March Core Updat3). I believe it was due to low quality content I had recently published (my bad). Low quality doesn't mean it was bad or AI but simply low quality. I removed all those pieces (almost 50% of the site that was). Updated the other pages, I waited for two core updates. Nothing happened. I was 100% the site is good now and need to rank. So changed the domain and I can see some pages are even restoring their previous rankings from the old domain's rankings before the hit.
