Hi,
I took this paper for our upgrade.
Step by Step how we have done this.
1. Stop vCenter 4.1 with hostname "vcenter4.domain.at"
2. Backup vCenter 4.1 SQL DB with the Database name "vmware_vc4"
3. Restore this Backup with another DB Name - "vmware_vc5"
3. Konfigure SSO DB with Database name "vmware_sso"
4. Install a new Windows Server 2008 R2 x64 with hostname "server1.domain.at",
configure ODBC so it points to DB "vmware_sso" and install SSO on this Server.
5. Install a new Windows Server 2008 R2 x64 with hostname "server2.domain.at" and install Inventory Service on this Server.
6. On the Server where SSO is installed, "server1.domain.at", another ODBC connection is configured for vCenter Server which points to DB "vmware_vc5" and the vCenter Server Software is installed. When the Database upgrade warning appears, I select "Upgrade existing vCenter Server database".
7. Install a new windows server 2008 R2 x64 with hostname "server3.domain.at" and install Web Client on it.
All components could be installed without any errors.
But when I loggin with Web Client, the hostname of the vcenter Server is the old one - "vcenter4.domain.at" - on which vcenter Server 4.1 resides.
I have installed vcenter Server 5.1 on "server1.domain.at" with a clone of the old venter Server 4.1 DB.
We can not use the old vcenter hostname "vcenter4.domain.at" because vcenter server 4.1 will be deleted (it's a vm) and the dns entries will also be removed.
So, I don't know what's wrong on our installation process.
