Cannot unregister a GlobalID field if data is versioned or replicated

Remarks

This method converts a field of type GlobalID to a field of type GUID.

The object must reference an unversioned ArcSDE feature class or table.  Use the IVersionedObject3::IsRegisteredAsVersioned property to determine if a dataset is versioned.  Additionally the dataset must not be replicated. Use the IWorkspaceReplicasAdmin2::IsReferencedByReplica method to determine if the dataset is part of a replica.

A Global ID field must not already exist on the dataset referenced by the object. Use the IClassEx::HasGlobalID property to determine if a dataset has a Global ID field.

The columnName must reference a field of type GlobalID in the dataset referenced by the object.  The IField::Type property can be used to determine a field type. 

Errors will be returned if any of the above requirements are not met.
