Importing a Deprecated PDM Logical Model

If you have previously created a PDM with the logical model DBMS, you will be invited to migrate to an LDM when you open it.

  1. Select File > Open and browse to the PDM logical model to open.
  2. Click Open to display the Import Logical Data Model dialog:


  3. Choose one of the following options:

    • Convert the model to a logical data model – Note that only tables, columns, keys and references are preserved

    • Change the DBMS target to "ANSI Level 2" and open it as a PDM

  4. Click OK to open the model.
Note: A PDM with the logical model DBMS that had been generated from a CDM will retain its links to the source CDM when you convert it to an LDM. However, for any PDM generated from the old LDM, you will need to restore the generation links by regenerating the PDM from the new LDM, using the Update existing PDM option (see Core Features Guide > Linking and Synchronizing Models > Generating Models and Model Objects).
