Esxi 9 install

[TeleFragger]

I have a Lenovo P720 that has esxi 8 on it. Want to install 9. I know many alements since Broadcom bought vmware but I still run it.

Anyway as mentioned 8 installed fine but 9 stops here.
Any guidance appreciated!

Silly question for you, have you checked the website for that software or the forums for it?

Outside of that I can only suggest doing internet searches or Reddit.

Sorry.

Turns out it is my cpu's are not supported. Force upgrade and broke it... Went back to esxi 8 cuz not spending $500 x2 for a test environment.

I try to always use the vendor supplied iso to install and you'll likely know before hand if your hardware isn't supported. I also find it easier to manage the newer image based patching when you can import the vendor supplied version for the baseline as well.
