Hi,
I'm planning to perform an in-place upgrade of our vCenter from 5.1 Build 1123961 to vCenter 5.5. Requirement is to retain the existing performance data of VMs, Hosts.
As per the table on page 6 of http://www.vmware.com/files/pdf/vcenter/VMware-vCenter-Server-5.5-Technical-Whitepaper.pdf , in-place upgrade upgrade looks like will retain the performance data.
Just wanted to confirm if this is practically true or we need to consider any instructions or guidelines, before performing in-place upgrade?
Please advise.
