Upgrading SQL Databases: vCenter, Update Manager, Single Sign On

[dflint]

We are moving databases from a SQL 2005 Server to a SQL2008 server. The vCenter database has been moved by changing the server name of the DSN.

(The latest SQL Native Client 10.0 did not seem to be required for this change)
I'm looking for guidance in moving the databases for Update Manager and Single Sign On.

ESXi 5.2

Thanks.

Sorry about the typo. Should be ESXi 5.1
I am running the installs for Single Sign On and Update Manager to change the database locations.

Following reinstalls the Inventory and vCenter Server services would not start.
Called VMare support. On the phone with them for a total of 8 hours!
Finally blew away the vCenter Database and started with a clean database which resolved the issue.
