Upgrade Vcenter from 4.1 to 5

Hi all,
        I have to upgrade my vcenter server 4.1 to the new Vcenter 5.0.

By now the server is using the sql 2005 express bundled with vcenter 4.1.
Because there are a lot of problems in upgrading the server maintaining the local sql express instance (4.1 uses sql 2005 express 32 bit anche 5 use 2008 r2 express 64bit, no way to upgrade directly the 2 instances, no way to use data migration tool because is incompatible with vcenter 4.1...) I decided to move the db to an external 2008 standard x64 sql server.

Maybe I have to do some operations except to move the db to the new sql server and modify the DSN of the vcenter?
Nothing to do about the ADAM services?

Thank you in advance.

If you have already moved the vCenter DB.

1. Create a new ODBC connection on the vCenter server to be installed.
2. Check the ODBC connection works correctly, using the Test function in the ODBC wizard.
3. Install vCenter 5.0 selecting this ODBC connection.
4. When prompted to Upgrade Database select YES.

This is how we do most of our upgrades.

Ok, so there's nothing to do rather than detach and attach the db to move the db from the local sql 2005 express x86 instance to a full sql server 2008 standard x64?

The only think that leave me a bit worried is that during the setup wizard I cannot select the domain user configured to run the vcenter server and web management services....
I can only select local admin...
Maybe should be a problem if I change the logon account after the installation??

Install, and change service later, if required to use a special user account.
