Oracle APEX - Moving multiple pages to a new App

Running the current version of Oracle APEX. Looking for best practices / sanity check for extracting/moving a “module” to a new app.

I have an app in a Workspace. This app has around 70 pages, 5 of which go to a specific "module" / functionality. I want to extract/move this module to a new/not yet created app within the same workspace. This new application WILL need it's own administration page. Never having done this before, I want to make sure I get this right. Because of the amount of Javascript involved, I need to keep the page numbers the same. There are no private reports, only public reports.

Expected steps:

1). Create a new app in the same workspace, with Administration page

2). Do I export the whole app, and only import those pages I am wanting? (Is this even supported?). Do I have to export page at a time, etc. then import?

3). Update user access on the Administration page.

4). Update menu structure

What is the best/proper approach to do this?

Solution

I'd probably

export current application
import it (either choose new ID, or let Apex set it)
new application should work just the same as the original
remove all pages you don't need
- in App Builder, click the "Utilities" icon
- on the right hand side of the screen, under "Page Specific Utilities", choose "Cross Page Utilities"
- choose "Delete multiple pages"
- mark checkbox for pages you don't need
- click "Delete pages" button
run the application
check how it looks and - if necessary - fix whatever might be needed
