HP Gen 8 Microserver- Windows 11

I am looking for some advice, with OEM support for Windows 10 ceasing later this year. I have been looking at upgrading my HP Gen 8 to Windows 11, I attempted it with the workarounds for only having TPM 1.2 etc but it failed, not sure why. What would you do? Leave as is? Try and work out why Windows 11 upgrade failed? Upgrade to newer hardware/move to a later gen of microserver (Gen 10)? Change OS?
