thank you, gentleman for your help. There is a mysqli module on my servers for use with the newer version of php.
I tried your solutions to no avail but here is what I did to eventually get the system to work, which I did finally achieve earlier this morning. It wasn't pretty but it worked.
I made a completely fresh install of the latest version of myBB with a completely new database. I duplicated my old forum database into a new forum database. I downloaded the Merge software and ran that.
I did that two times with two different downloads of the software. Both times i got warnings that the IN_MODULE was throwing off an error. I tried to just continue but it eventually failed in the configuration aspect of the Merge Wizard.
So, I had the unpopulated board. I rewrote the config.php file to point at the copy of the database of the old forum.
That worked. My myBB forum is now up and working on PHP 7.3
