I upgraded 1 of 2 hosts just fine, but the second does not recognize that Esxi is installed on either virtual disk.
When using an ISO to upgrade the server, it wants to do a clean install. I have a lot of configurations with ISCSI and vmotion networking, that I really do not want to replicate with a clean install if I don't have to.
I am going from version 5.0.0 build 469512 to esxi 5.5.
Any ideas on anything I can look at to see why it is not recognizing that it is installed (Installed on 1st Virtual disk)
