When re-importing a plan, either manually or via Back4, few operations are performed differently from the first import. Here is a list of the differences:

•All existing editorial material (material which is seating on an editorial layer) is unchanged.

•When the new Ads plan has fewer pages than the previous one the pages which no longer exists in the Ads plan are converted into logical pages.

•Here is a sample of how those pages appear in an edition:

 
and in the Fred pages navigation panel

As you can see the editorial content (page 180) is still there so it can be moved into another page.

•The page workstate is not overwritten when the GN4 page workstate is one on the “list of worstate to keep” option
