Update Schema of a DGN file

QUESTION:  Getting an Informational dialog about reference models having old Schemas.  What is this for?

ANSWER:  This is just an informational dialog telling a user that the reference files have old schema. Schema is something internal to a file and user does not have any control.  It is used internally for creation of the model.

There are two ways one can update the schema of the file:

• Open the reference file inside the working file by opening the References dialog and then right clicking on the reference file in question and choosing Activate.  After the file is activated, go ahead and deactivate it. Or
• You can open the reference file directly by using the latest version.
