Alright, here we have some numbers for November. You can view the details in a spreadsheet.

(Table moved to description for better editability)

All arguable. Better ideas welcome.

Yep, I think this is a reasonable approach to measure both current state and change over time. And it's nice to see how far we've come already. :-)

What do you think about including RT/ops in the spreadsheet as well? I know we said "developer" teams in the Q2 goals and I don't want to move the goalpost on you -- but purely for tracking purposes it may be nice to make visible as well.

We're no longer making any changes in Trello, except to track what needs to be migrated to Phabricator. See e.g. "Send to Phabricator - Collaboration-Team board" at https://trello.com/b/HD0lBssr/flow-backlog .

We're using only the board at Collaboration-Team. Currently, we don't have a separate sprint board the way we did on Trello, but we're not ruling that out for the future.

Online spreadsheet updated accordingly with 0.75. Now the total is 55% and Trello is 21%.

Fundraising-Tech has set a first foot in https://phabricator.wikimedia.org/project/board/41/ . @atgo reached out to find answers and some advice. Their current plan is to start cloning tasks in Phabricator, and they don't intend to migrate all their Mingle cards there, taking this as an opportunity to refresh their backlog to match reality. (these are my own words and my own understanding of the situation)

Online spreadsheet updated accordingly with 0.25. Now the total is 56% and Mingle is 58%.

Last week Operations migrated most of its RT tickets to Phabricator. Two queues are remaining in RT for now: access-requests@ (T84861) and procurement@ (T84862).

Language Engineering is about to start their third sprint in Phabricator. They are discussing the migration of their tasks in Mingle. @Arrbee provides some details in T829#939585

Online spreadsheet updated accordingly with 0.75 for Operations and Language Engineering. Now the total is 63% and Mingle is 67%.

T831: Migration of Fundraising Tech team to Phabricator is resolved! Now the total is 67% and Mingle is at 92% (pending the completion of the Language Engineering migration only).

For what is worth, Ops-Acces-Request is now run via Phabricator as a pilot. This is one of the two RT queues that were not migrated. Once this process is consolidated, Procurement (the last RT queue T84862) will initiate its migration as well.

We had Engineering Community quarterly review yesterday. We talked about the percentage of teams migrated and the special attention required to the Trello users.

I forgot to add these metrics to the slides (ooops!) but I just added them now, for posterity: https://commons.wikimedia.org/w/index.php?title=File%3AEngineering_Community_Quarterly_Review_Jan_2015.pdf&page=16

Could the statistics be updated for January pretty please? :)

The Mobile-Apps team is running a test sprit to get a full taste of Phabricator: Mobile App Sprint 52 - Android & Mobile App Sprint 52 - iOS

Thanks to this, the Trello stats move from 21% to 29%, and now the total adoption is 70%. I hope the test is successful, and the Mobile apps team does stay in Phabricator!

According to T821#1055193, the #§Collaboration-Team migration from Trello is complete!

Thanks to this, the Trello stats move from 29% to 33%, and now the total adoption is 72%. The Collaboration team also sets a precedent being the first team leaving Trello in archive mode, moving all their planning and sprint work to Phabricator.

T829: Migration of Language team to Phabricator has been resolved! Mingle stats are at 100% now. Total adoption moved a bit up, and is now in 73%.

The Gather team was created in the middle of this transition. Even if I have heard about the project, I was not aware of its existence as a formed team until recently, and I was kind of dismayed when I learned that they had started using Trello instead of starting fresh with Phabricator since Day 1. Anyway, @JKatzWMF & team were probably actually surprised, and as soon as they realized the Phabricator trend they made quick steps for their migration.

And now...

I ran the scripts to migrate the Trello "Gather backlog" board to Phabricator Gather project, one column at a time. Seemed to work, see log.

Gerrit 193316 has the updated username mappings and comment tweaks.

Great news! I have added the Gather team to the spreadsheet in the month of February, but I am not changing any values in previous months to keep the data frozen. Now Trello has gone from 33% to 43%, and the total has gone from 73% to 75%, a symbolic number.

This doesn't affect the % of teams migrated, but it is worth noting that thanks to Matt, S, and others, the Trello script was used in the T1247: Migration of Growth team Trello boards to Phabricator, a legacy including valid open tasks that probably would have been forgotten in trello.com. Now it can be found in the Growth-Team archived project.

There was some progress on March.

The Mobile Apps team is using Phabricator for their current sprints and general backlog, but still has the legacy in Trello (0.75)

The Design team has been using Phabricator incrementally, as the teams they work with have been moving to Phabricator as well (and they are stopped by the teams that haven't yet). 0.75 reflects better their current situation, and the details can be found at T832#1157637

With these changes, Trello migration is now at 54% (arguably a 'simple majority'!) and the overall indicator has moved from 75% to 79%.

It is also worth noting that Operations has been working on moving the Procurement queue from RT to Phabricator, but they are not quite there yet (T93760).

fyi: T96959: Migrate user research Trello board to Phabricator \o/

This and the consequences of the reorg (with designers now fully embedded in other teams) made me resolve T832: Migration of the Design team to Phabricator.
