Downgrade ESXi 5.5 to ESXi 5.1

Hello all,

Would it be possible to downgrade a host from ESXi 5.5 to version 5.1? If yes, what is the recommended procedure?

Thanks,

axeon

Hello Axeon,

you can try roolback to previous image via Shift+R during initial boot process of ESXi.

If its not possible you can try to catch host config via HostProfile feature (if you have license), reinstall host and try to attach and apply profile to newly installed host.

Before rolling back dont forget that VM hardware version 10 its not supported on 5.1 hosts

Reagards,

P.
