TL;DR: Reorganise work as it progresses — move subitems between parents, copy them across boards, archive completed batches, or convert between items and subitems. Pick the recipe that matches the action and the trigger.
When to use these automations
A subitem completing a stage should hand off to another parent or board
Bulk-archive completed subitems on a status flip
Promote a subitem to a top-level item (or vice versa) when its scope changes
Generate a parallel item in another board for cross-team handoffs

Deep-dive
"When subitems status changes to something, move subitem to this item."
Status-driven handoff to another parent on the same board.
These conversion recipes also live in the new Convert items ↔ subitems landing — the canonical home for the full set of 9 conversion patterns. The recipes below are kept here for discoverability when you start from a Move/archive/copy mindset.
Recipe (exact text from automation center)
Use when
"When subitems status change to something, create item in this board and map values where both column name and type match."
Subitem reaches a stage where it needs its own top-level item.
"When subitems status change to something, create item in another board and connect using connect column."
Cross-board ripple — subitem completion creates and connects an item elsewhere.
"When subitems status change to something, convert subitem to item in this board and map values where both column name and type match."
Promote in place — the subitem becomes a top-level item, parent loses it.
"When status changes to something, convert item to a subitem on this item in this board and map values where both column name and type match."
Demote — an item becomes a subitem under another item.
"When status changes to something, convert item to a subitem on this item in this board."
Demote without column mapping — fastest version.
"When an item is created, convert it to a subitem of the item with the same name in this board and map values where column type and name match."
Inbound items get auto-nested under their matching parent.
