When database has a non standard collation and a Disabled Index View is generated during sync, this will throw an error as the create view statement cannot properly determine the collation to use.
This will cause the upgrade to fail with an error like:
'[Microsoft][ODB
C Driver 13 for SQL Server][SQL Server]Cannot resolve the collation conflict between "Latin1_General_CI_AS_KS" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.
