Would this resolve the open patches problem in phabricator where we carnt view open patches but can merged patches.

And when will this be done.

And will the changes still be open on gerrit or migrated to phabricator and closed on gerrit.

Since no new changes would be created in Gerrit, and the old changes would be migrated to Differential, then yes, you'll be able to see everything in Differential.

And when will this be done.

Right before the migration.

Migrated then Gerrit will be marked read-only.

Ok thanks for replying.

But do you know when the migration will start. And would we have to use the arc command or can we use the normal setup with minimal changes such as only a change to the url.

@Paladox: You will have to use arc.

Oh. Would there be a guide on mediawiki on how to do it as simple as possible like there is one for gerrit and for git.

T117058: Initial documentation of example Differential workflows (with Gerrit equivalents)

Thanks.

Plan of action:

For each open patch in gerrit:

• apply the patch locally against master
• run arc diff
• adjust differential revision owner as appropriate

Is there a chance to make this automatically?

Why would it be done manually, other than for trials?

When do the trials start.

@Luke081515: it will be automated, but each repository will be done one-by-one on demand.

@Paladox: trials start as soon as possible. That is to say, right now.

@mmodell thanks for replying and which repo are you doing the first test on.

Once the trials are successful would it be open fully meaning every repo gets done,

Would diffusion also be turned on for everyone to use or only when gerrit is turned into read only mode.

@Paladox: I'm not sure. We are taking applications for guinea pigs.

@mmodell oh ok.

I'm going to reword the description based on the current plan which is to migrate repositories in phases (see https://www.mediawiki.org/wiki/Wikimedia_Release_Engineering_Team/Project/Differential_Migration for the overall huge context, but look for "phase 1 migration" etc).

So, I'll rework this task to be about creating the tool/script that will do this migration of open changes from gerrit to differential that can be run against specific/groups of repositories. Then, right before any repository migration we'll run that script for that repository.

I've typed repository too many times :)
