As per T434 , in the following days I plan to scan the levels of use of Phabricator by all the WMF product & engineering teams. Please keep the description of this task up to date.

@Spage, I wonder whether you were aware of this task. The Growth team is now orphan/defunct, but @Mattflaschen thinks it is worth migrating their cards to Phabricator not to lose that work completely. Would you like to work on this at some point in March?

And the rest (I think everyone else doesn't have a Phabricator account or isn't currently a member of the Trello board):

I did a test import of the Growth > Current Sprint To Do column to a Growth-test board on our test phab instance, see https://phab-01.wmflabs.org/project/board/63/

It's also nice to have the done stuff for historical reasons.
The priority is the main board (both archived and unarchived cards, since archiving done cards was normal procedure)

I'm not sure preserving history is a great reason. I know of no plans to turn off Trello for WMF, so anyone who cares can visit these boards. FWIW Danny left lots of Flow cards in Trello un-migrated.

Also the script skips archived cards. I can take out that check (lines 308-310 in trello_create.py), but I think they'll migrate as open tasks so you'd have to bulk change their status (or hack the python!).

Before I can proceed I need to know the destination Phabricator project(s) for the migrated Trello cards? Please create analogous Growth and Growth-roadmap projects in Phabricator, or give me some other board for these cards, like MediaWiki-extensions-GettingStarted.

I don't really care what columns you want, since trello_create.py doesn't do any board manipulation – all the cards just show up in the default (Backlog) column. I haven't found a better way to put cards in the desired column than moving a card at a time. I can either import a column at a time, or the entire board at once. The first way ensures all the cards in one Trello column appear adjacent to each other in the Phabricator backlog column.

I feel migrating archived cards may be useful, but Trello always had a slightly transitive feel, so I don't have a strong preference.

I've created Growth-Team. I think it's fine to merge everything to there.

+1 I don't have a strong preference either way.

OK, this is done. Matt Flaschen already went in and cleaned some up.

Because I care I added links to Trello attachments to the task description.

https://www.mediawiki.org/wiki/Phabricator/Trello_to_Phabricator/Growth_team_import has detailed logs.

• I migrated each column of https://trello.com/b/FdtPTV2y/growth , all the cards appear in Backlog.
  • Recreating the Trello columns in the Phabricator workboard and manually dragging cards is left as an exercise...
  • Migrating the Trello "Done" column pulled in dozens of old cards that were "Completed", I think this might be a format change Trello made a while ago. Anyway I used Maniphest query's batch-edit feature to set the status of all of them to Resolved, with a comment.
• I migrated https://trello.com/b/VtfU41K8/growth-roadmap all at once, and dragged all its 17 cards to an "old-Growth roadmap" column.

I didn't migrate archived cards.
