I would first put everything back under the old PHP version to make sure it works to begin with.
Once that works, overwrite the files with the new vBulletin files, then change the PHP version to PHP 7, then run the upgrade script.
I've done it this way many times without any issues. If you have a large forum (millions of posts), I would run the upgrade script through SSH.
Just throwing in a what of scenario here.
what if my host says I cannot downgrade my version of PHP. Is there another way around it?
