Upgraded the Main Computer (hosting the Amazing Charts V 10.0.1 database) from Win 7 Pro to Win 10 Pro without issues. It took 2 hours but there were no problems. Amazing Charts works. Updox works. Network works. Didn't need any database re-credentialing. My spouse jokes I must have done something wrong!

I just downloaded the Windows 10 Media Creation tool direct to the main computer and ran it.

It installed a fully licensed Windows 10 Pro using a "digital license" (did not have to buy additional license).

Thanks to all for the helpful advice.
