The importer copied URLs, targets and cross-menu parents as exported, so
a javascript: URL or a _parent target broke the first admin save of the
row, and an entry under a parent in another menu vanished from the
public tree. Kept entries now get a trimmed or cleared URL, a cleared
target and a top-level place in their own menu, each with a report
line.
- link to url, blog_categories to all-journal-categories, --map old=new on top; page entries dropped
- entries of unknown types or stale registry references dropped with their subtree, one report line per dropped or remapped entry
- ids, menu_id, parent_id, nest columns and sort_order kept; setval for both tables; --force, --dry-run, empty files copy nothing
- scripts/winter-export-menus.sql and winter-export-entries.sql
- TestMenuImportSmoke
