Hi,
I have to upgrade two 5.1 vcenter servers (windows version...non-appliance) that are linked together. I read on Derek Seaman's blog (http://www.derekseaman.com/2013/10/vsphere-5-5-install-pt-3-upgrading.html) that you just need to unjoin the two vcenter servers first then upgrade and rejoin but what I do have a question on is the multi-site SSO that was configured in 5.1. How does does the upgrade work with that?
When upgrading SSO will it detect that it is part of a multi-site SSO and upgrade accordingly, or is there something special that you need to do before/after/during?
Thank you,
Matt
