Checking Whether the Collation of the Destination Database Is Correct

The primary key or unique key in the destination database contains a collation ended in _ci. The collation ending in _ci is case insensitive, so an error indicating duplicate keys may be reported during synchronization and cause the synchronization to fail.

Failure Cause

The destination database collation is not supported.

Handling Suggestion

Change the destination database collation to a case-sensitive collation (not ending with _ci).
