There are two options for doing what you want. The first is to create a new version, which makes a total copy and gives the new application the same name but a different version number.

However, there are drawbacks to this. If you want to delete the latest version and start over, you are stuck unless you delete earlier versions.

This can also have some nasty ramifications if you are sharing elements between applications.

The second approach is to use the migration facilities to export the application and then reload it. The steps involved are:

1. Extract the desired application(s) using the extract utility. (These utilites are in the Managment Menu).
2. Export the extract tables.
3. Delete the extract tables
4. Load the resulting .dmp file back in. It will warn you that an application of the same name exists and force you to rename the new application.

All of this is described in the Administration manual, and the utilities are all in the same menu (whose name escapes me, since I only have 5.1.6 loaded).

This second method also leaves the original application unfrozen, and allows parallel development.
