Upgrading vCenter DB 4.1 to 5.1

Hi,

I want to upgrade our Infrastructure from 4.1 to 5.1

Host name of vCenter Server 4.1 is as05345

I have installed 3 new servers:

as10446 will get the following Services -> SSO + vCenter Server

as10447 will get the following Service -> Inventory Service

as10448 will get the following Service -> Web Client

So SSO Service and vCenter Server have both as10446 as Hostname.

We backuped our vcenter 4.1. SQL Database and restored it with a new DB name.

Then I installed sso. When installing vCenter Server, i do an upgrade of the db and NOT a new installation.

But when installation has finished with all components, vCenter is registered with the old Hostname as05345

and not with the new one as10446.

What's wrong?

regards

Andi
