I have replaced our vCenter server from 5.1 to 5.5, new hostname. The old vCenter server was connected to veeam and i have made a new connection with this new vCenter server, and that is working without any problems.
But i cant delete the old one from veeam.
Here is what i have tried, Enterprise Manager and the tab Configuration / vCenter Servers, here i have both the old and new server, vcenter server status for the old one is Warning and the new Ok, i select the old one and click Remove, Yes at the dialog about Remove vSphere Web Client plug-in. next dialog is a login at vCenter server and the text Failed to connect to vCenter Server, and its offline so i cant login at it.
I guess that there is somwhere else where i should delete this old server, so my guestions is where.
