To: Wikimedia developers <wikitech-l at lists.wikimedia.org>


We are polishing the last details before starting the Bugzilla migration to
Phabricator on 21 November at 00:30 UTC.

You can find all the details of what will happen next in the timeline at

MIGRATION WEEKEND

Basically, Bugzilla access will be restricted to read-only, Phabricator
will be pulled, and we will start the migration. If all goes well, by
Monday 24 Phabricator will be back with about 75k tasks, and Bugzilla will
be archived in old-bugzilla.wikimedia.org.

During this period, we will redirect users to a page asking them to
postpone their bug reporting unless it is so urgent that it cannot wait
until Monday. In that case, they can use  #wikimedia-bug2phab on IRC and
mediawiki.org's Support Desk.

If you registered in https://phabricator.wikimedia.org before the
migration, your Bugzilla activity will be probably assigned to you by the
time you check the site. Otherwise, you will still be able to register and
claim your activity, which will be assigned to you within a couple of hours
or a couple of days, depending of the queue.


KNOWN ISSUES

We are confident about the stability of Phabricator and also about the
reliability of the migration process. However, there are several known
issues related with data and features that will be missing next Monday.

We cannot assign to Phabricator tasks the same number as their Bugzilla
equivalents. Instead, automatic redirects will link old Bugzilla URLs with
their corresponding new Phabricator tasks. phabricator.wikimedia.org has
already >1300 tasks with numbers taken. The migration needs to be done by
batches of bugs instead of sequentially, which makes the mapping of numbers
more complicated. Still, smaller numbers will correspond to older bugs, and
we will do our best during the weekend to improve the sorting.

Votes and saved searches cannot be migrated. Users willing to have their
equivalent in Phabricator (tokens a new saved searches) will be able to
access their accounts in old-bugzilla.

A feature that we expect to be missed is suggestions for duplicates when
creating a new task. Even if Phabricator's search is powered by
Elasticsearch, we feel like it needs some fine-tuning to get to Bugzilla's
efficiency. Advanced Bugzilla users will also find that some actions take
more clicks (assigning blocker/blocking tasks, for instance). In general,
most fluent Bugzilla users new to Phabricator will need a few days to get
used to how things work in Phabricator.

There is a complete list of known issues at
https://www.mediawiki.org/wiki/Phabricator/versus_Bugzilla#Known_issues --
and we will keep working on them after next Monday.


IMPROVEMENTS

We expect that the improvements will make the change worth right after the
migration, of course. A simpler and cleaner UI that works on mobile,
Wikimedia SUL, bugs and features living together, ability to associate
tasks to several projects, workboards, and many more features are waiting
for you!  :)
