Changing collation of Virtual Center Database

I needed to change VMWare ESXs Virtual Center 2 Database collation while moving the DB to another MS SQL server using different collation, you might not need to change VC2 DB collation but I think it is better to use default server collation. As usual for most databases I got the error below; because of an object dependent on database collation.

• Alter failed for Database VirtualCenter2.  (Microsoft.SqlServer.Smo)
• An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
• The object sys_PhysicalIndexStatistics_Wrapper is dependent on database collation. The database collation cannot be changed if a schema-bound object depends on it. Remove the dependencies on the database collation and then retry the operation.
• ALTER DATABASE failed. The default collation of database VirtualCenter2 cannot be set to SQL_Latin1_General_CP1_CI_AS. (.Net SqlClient Data Provider) (Microsoft SQL Server, Error: 5075)

You can easily deal with this issue by using the steps below.

1. After restoring the DB on target server , browse to VC2 DBProgrammabilityFunctionsTable-valued Functions, right click on sys_PhysicalIndexStatistics_Wrapper then select Script Function As > Create To > New Query Editor, it will create the query needed to re-create the  sys_PhysicalIndexStatistics_Wrapper object.
2. Delete sys_PhysicalIndexStatistics_Wrapper
3. Change collation of the database.
4. Run the query you have created on step 1. , check if sys_PhysicalIndexStatistics_Wrapper created successfully.
