We got some problems in the datacenter with the virtual vCenter 4.1 server and decided to revert to a physical machine again to run vCenter.
After some good experience with the VMware Datamigration tool I tried to use this option again to migrate the 4.1 vCenter/VUM database + settings to the new host.. but… it’s not supported!
[ERROR] vCenter Server version not supported
[WARNING] vCenter Server does not satisfy migration prerequisite
One of my colleagues was migrating vCenter 4.0 database to vCenter 4.1 by using the Datamigration Tool located at the vCenter Installation CD. After running the Backup.bat script he received the following error:
DB logs: Msg. 3013, Level 16, State 1, Server <name> , Line 1 BACKUP DATABASE is terminating abnormally
Sqlcmd: Error: Microsoft SQL Native Client : An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections..
