I am having the issue that pre-upgrade checks are failing upon trying to upgrade an external PSC.
As in this case: 6.5U2c > 6.7U1 Pre-Upgrade Check Failed
I am getting Cannot validate target appliance configuration as not enough information from the source appliance can be collected. For more details check out the server logs
However, this is a fresh installation. I have setup a lab environment with two PSCs and two vCenters in enhanced linked mode.
This happens when I try to upgrade the first PSC.
I thought perhaps I have to converge them to an embedded PSC first, but that doesn't work either. When I put the FQDN of the vcenter in the JSON, it tells me it cannot resolve to hostname. The hostname is pingable though.
When I switch over to an IP instead, I get a script error missing double quote.
This was on 6.7 iso.
I then thought perhaps I need to use the convergence script from 6.5 but here I am told that the version of the iso does not correspond to the vcenter. That is true as I upgraded the PSCs and vCenters after installation to the latest 6.5 release.
However there is no iso file for that build number as far as I know.
So can somebody tell me what the correct method of moving from external 6.5U2 enhanced linked mode to embedded 6.7U1 enhanced linked mode is?
I will attach the logs from my update attempt through the UI.
Thank you for any help you can provide.
the upgrade from 6.5u2 to 6.7u1 is not supported as it is considered back-in time.
