Defender found some issues

I recently installed Defender, ran a scan, and it found 7 issues. That was done when I was on a shared server a couple weeks ago.

Then, recently, I migrated my multisite to a dedicated server.

My question: should I run another scan to see if the same issues migrated over to the new server or take care of the old issues first?

I have not deleted or fixed any of the original 7 issues found.

I have granted access to my dashboard.

Thanks, Joe.
