@EBernhardson Is this expected work now (at least if Occupy Pages is not used)?

Not yet but In theory this should be trivial. We just change FlowHooks::onMovePageIsValidMove to update the Workflow object instead of failing the move and see what happens :)

well, not directly update from that hook perhaps, but thats the general idea.

Why is this declined? This is the only task I could find about it, and we will have to implement this at some point, most likely.

Copying across old comments from trello:

@Spage wrote (June 21, 2014):

Currently if you use Special:MoveTo to move a Flow board, or a page and its Flow-enabled talk page, all the content is left at the old board, and Flow ignores redirect. To fix this:
Flow would have to decide if the new name is or can be a Flow board and disallow certain moves (which relates to how pages are Flow-enabled, G-10. Spike: Special page to enable/disable Flow on pages).
Flow would have to update its tables so content is associated with the new board name.
Until this works, T68891: Until Flow pages can be moved, prevent someone from trying is to block moving Flow boards.

(See also: description in the "Move/rename a board" card:)
As an advanced markup editor I can move a page to a new page title through Special:MovePage, and have the Flow board associated with that page move with it. In addition, I can manually move that Flow board, independent of what happens to the associated page, in the case of (ferinstance) Wikipedia-space pages.
Acceptance Criteria:

• Special:MovePage allows for the move of Flow boards;
• Special:MovePage allows for the move of Flow boards attached to a page the user is trying to move.

This might "just work" once we stop using the $wgFlowOccupyPages whitelist in favor of G-10. Spike: Special page to enable/disable Flow on pages . The new page name would have the Flow content model thus would still be a Flow board, and @werdnum thinks its topics refer to their starting board by page ID, not by title, so they would update to indicate they came from the new Flow board name.

Currently it doesn't work. Special:MoveTo fails with internal error, the renamed Flow page has the JSON identifying the UUID for the board (good) but has contentmodelt="wikitext" instead of "flow-board", the old Flow page doesn't have #REDIRECT in it, etc.

I can combine the two articles (merged content into one) - the second board sign on the themes of the first board, or any method [[T88140| Moving topics between boards]] move all topics from one board to another board with topics. For such action need a way to cancel? Such action would make multiple log entry?
