Upgrade from 3.7.1 to 5.6.9 (Latest)

Initially installed 3.7.1 using MSI and planning to upgrade to latest version 5.6.9
Is this the right approach?

But on the portal, i can see ‘New version Available 3.10.5’ and not the 5.6.9 !
Does it mean I cant directly upgrade to 5.6.9 ?

Any instructions / suggestions on how to proceed will help. Thank you

the docs state that upgrading major versions require uninstalling the old version, and then installing the new

Upgrade | PowerShell Universal

Other sections of the Update docs covers backing up data etc.
