You can perform refactoring by using the following approaches:
Rename — Enables you to rename all occurrences in the associated XSD, WSDL, and BPEL files.
Safely Delete — Enables you to check for references to the component before you perform the delete.
Undo — After performing a Rename or Safely Delete action, you can undo that action.
Redo — After performing an undo of a Rename or Safely Delete action, you can redo that action. Menu that shows the refactoring options
You can also rename a component by changing the value of the Name property. The WSDL Editor renames all occurrences in the same file, but not in other files.
