Upgrade From Windows 7 to Windows 10 - Advice Needed!

Hello All,

I'm thinking to upgrade from W 7 Home Prem. to Windows 10 on two desktops. (The over the top way). Am I right in thinking the best way to go about this is to first uninstall my Norton Security (Latest Version 22.7.0.76), start the upgrade process with Microsoft, then let all the updates for that kick in incl. Windows Defender. Once all that is done then re install my Norton Security? Also remembered the disabling of fast start up in Windows 10. 

Any advice on the above would be greatly appreciated.
