Migrate from vCenter 4.0 to 4.1

Currently I have a SQL Database that can't be backed up too many resource groups and a general CF of infrastruture I have inherited.

I am looking to start over.  Here are my thoughts

Install a new instance of vCenter 4.1u2 on a new 2k8 R2_x64 Server and a New DB instance.  This would replace the 4.0u2 on 32bit 2k3.

What would be the best way to go about this?

I don't care about any data in DB.  My thoughts are to shut down vCenter and tell peopel if they need any data they have 30 days then at the end of 30 days delete the db and uninstall vCenter on the old Serer.

If you did want to keep the data from your old database, you can use the Data Migration Utility, which copies the data from old DB, and populates the new DB, and installs vCenter Server.

I forgot to mention that I can not get a backup of the database. When the DBAs try it fails and registers I/o errors in the logs

It might be worth just trying Data Migration Utility for 5 minutes?

otherwise start a new install, new server OS, new SQL, new vCenter.

If you build up the new server for VC and add in the hosts; you likely won't suffer any downtime of the VM's and will be done fairly quickly.  There are some considerations if you have DVS, though.  If you have custom permissions or resource groups then you will want to document them before adding in the hosts to the new VC.
