Updating virtualcenter Live granny
Once that’s done there are a few pre-requisites that need to be met and that will be checked by the upgrade process before the actual upgrade occurs.
The first thing the installer will do after asking for the SSO and VC service account password is run the Pre-Upgrade Checker.
With that, my suggestion would be to generate a temporary self signed certificate for the upgrade and then apply a public certificate after that’s completed.
Ephemeral TCP Port Error: Once the SSL mismatch error has been sorted you can run the pre-upgrade checker again.
After all that, in any case I got the warning below saying that the 5.5 SSL Certificates do not meet security requirements, and so new SSL certificates will need to be generated for v Center Server 6.0.0.v Center SSL and SSO SSL System Name Mismatch Error: A common issue that may pop up from the pre-upgrade checker is the warning below talking about an issue with the system name of the v Center Server certificate and the SSO certificate.As shown below it’s a hard stop and tells you to replace one or the other certificate so that the same system name is used.Post Upgrade Checks: Apart from making sure that the upgrade has gone through smoothly by ensuring all core v Center services are up and running, it’s important to check any VMware or third party services that where registered against the v Center especially given that the SSL Certificate has been replaced a couple of times.Server applications like NSX-v, v Cloud Director and v CO explicitly trust SSL certificates so the registration needs to be actioned again.
Update 1 brings new features to v Center, includes some security patches, and lastly fixes a few previous issues.
