Hi all,

Im trying to upgrade my hosts on a remote site from 5.1 to 5.5. I have done this on other sites using update manager but it keeps failing for these sites. I have checked the HCL and the servers are compatible. Im using the HP ISO from vmware but both 5.5U2 and 5.5U3 are failing.

Any tips on this?

What kind of error you're getting ? How fast is the connection between your vCenter Update Manager and the hosts you want upgrade ?

Hi,
what is your error message or symptom ?

Using Update Manager and the ESXi 5.5 source iso should work as you already have seen.
Nothing really different between this site and the others ?

Did you use the same iso as other sites ?
Is there a version difference in ESXi version you want to upgrade ?

There is other way to do it AFAIK, ssh for example, but not with the iso, more like an offline bundle (available on the same url you download ESXi iso).
