You can change the DBMS being modeled in your PDM at any time.
By default, PowerDesigner creates a link in the model to the specified file. To copy the contents of the resource and save it in your model file, click the Embed Resource in Model button to the right of this field. Embedding a file in this way enables you to make changes specific to your model without affecting any other models that reference the shared resource.
Triggers and stored procedures – triggers are always rebuilt when you change DBMS.
Physical options - if the syntax of an option is incompatible with the new DBMS, the values will be lost, even if you have selected to preserve the physical option. For example, the physical option in used by ASA is not supported by Oracle and any values associated with that option will be lost.
DBMS-specific objects - databases, storages, tablespaces, abstract data types, sequences.
Extended attributes - which are defined for a particular DBMS.
If you are changing DBMS within a database family, for example between Sybase ASE 12.5 and 15, all preserve options available are selected by default. The database objects not supported by the old and new DBMSs are disabled.
A message box opens to tell you that the DBMS has been changed.
