External PSC upgrade error 6.0 -> 6.5 - Installer can't determine source PSC/SSO version

[AlexSobolev]

Hi Colleagues,

I'm trying to update my infrastructure from 6.0 to 6.5.

I have the latest build (5202501) of external PSC 6.0:

External PSC health is Good. Auth is working fine, i don't see anomalies in PSC functionality:

I'm filling in all required source information about PSC and source vCenter/ESXi:

But installer can't determine version of source appliance:

Any ideas why is it happening happening and how to solve it?  May be i should change something in source appliance.

I tried to continue installation, but anyway it's failed as source version is incorrect.

Thank you in advance!

Hi,

Based on your screenshots I see that you are trying to do a "back-in-time-upgrade".

You are trying to upgrade from vSphere 6.0 Update 3 to vSphere 6.5.

6.5 was released before vSphere 6.0 Update 3 came out, so vSphere 6.5 does not "know" 6.0 Update 3.

I see two options for you:

- Wait for vSphere 6.5 Update 1 (which will be able to upgrade your current 6.0 Update 3 PSC)

- Deploy a new instance of the PSC 6.5 appliance and then join the same SSO Domain, join your AD, repoint the vCenter Servers to the new PSC and retire the 6.0 Update 3 PSC

Edit:

This is mentioned in the release notes of vSphere 6.0 Update 3: VMware vCenter Server 6.0 Update 3 Release Notes

Thanks a lot!

I will wait for 6.5 U1 and try to upgrade again.

vSphere 6.5 Update 1 is GA.

VMware releases 6.5 Update 1 – virtualfrog – daily virtual life

With vSphere 6.5u1 still an issue, exactly the same "error"-message. :smileyconfused:

Hi soehl,

The problem is that the root password of the Appliance is expired.
