Cube Migration Error

Hi,
I am getting below error while migrating cube to Analysis Services 2005 from 2000.


Unable to cast COM object of type 'System.__ComObject' to interface type 'Interop.Dso.IDbGroup90Ex'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{CE55E9E9-9597-4214-B21F-30C7683467B1}' failed due

to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).


I would appreciate if anyone passing the solution for the above if you have.


Regards,
