Can we focus furthermore to the results of upgrading a non-qualified device to Windows 11?

Question

Given that the only prerequisites not met are CPU and TPM (MoSetup),

and that a WIM file will be deployed with a 'DISM apply image' command after locating the file (version matched with index source);

predictably on the reboot there will be on-screen instructions to finalize the upgrade.

Given also that there can be ignored by the administrator the unavailability of the security fixes and what else typically expected for this scenario as with the end of support for Windows 10 by next October.

Is the specific process meant to move forward with keeping data and files?

A watermark and an option to go back in ten days is all to have to deal with most probably?

Excuse me the narrowed view about this, I could just use another hard drive to try, but it's unlikely to do anything anyway since it's 'not recommended' so kindly!

Sure, back-up will have been done in case it turns out inoperable.
