+Modifying Mesh Python scripts from SALOME 6 and before
+******************************************************
In SALOME 7.2, the Python interface for Mesh has been slightly modified to offer new functionality:
Scripts generated for SALOME 6 and older versions must be adapted to work in SALOME 7.2 with full functionality.
-
The compatibility mode allows old scripts to work in almost all cases, but with a warning.
-See also :ref:`geompy_migration_page`
+See also *"Modifying Geometry Python scripts from SALOME 6 and before"* page in the Geometry module's
+User Guide.
