Bill,

why are you moving to Tomcat 10 when Tomcat 9 isn't end of life yet? Did 
the vendor recommend Tomcat 10 with their application?

My advice would be to only change one thing at a time and then test it.

In your case:

1. Move your old working software stack to the new machine (old java, 
old tomcat, old everything) -> test it
2. Create a second tomcat 9 (download the latest one) directory next to 
the old working one, stop the old tomcat and copy everything from 
old-tomcat9/webapps to new-tomcat9/webapps. Also, check if any other 
file is present in the old tomcat (you already mentioned you a 
files.xml, etc). Also copy these files to the new tomcat directory. 
Maybe even check contents of files, they may have been changed in the 
old tomcat directory. Test it!
3. Update to java 11. Test it!

And so on.
