[~mark.proctor] asked me to make an inventory of what would need to happen if we ever migrate from github.com/droolsjbpm/ to github.com/kiegroup/. Technically this issue is very simply (just change it in GitHub), but organizationally this issue is difficult and dangerous: it needs to be done with care.

Preparation:

1) Get some experience

- Make a dummy repository in droolsjbpm, add some files and a few branches, fork it to your user account, add a PR on it, clone it 2 times:
-- Once from droolsjbpm
-- Once from your user account with droolsjbpm addes as upstream ("git remote add upstream ...github.com/droolsjbpm/...")
- Add some local changes on both dirs.
- On GitHub, go into the repository settings, in the danger zone and move it from droolsjbpm to kiegroup.
- Try using it from your 2 local clones ("git pull --rebase" or "git fetch upstream"). Copy paste the error messages for later use.
-- Fix it locally without recloning, without losing the local changes, etc. Record these steps clearly in a recipe to share with everyone else later.
-- Once it's fixed, see if you can do git operations without having to specify origin for the direct droolsjbpm clone. See also the git option "-u" - you'll likely have to add in the recipe as an extra step.
-- What happened to the open PR?

2) Reach out

- Talk to each type of person involved:
-- R&D developer
-- QA
-- Productization
-- Product docs
-- Community
- Make an inventory of references to "github.com/droolsjbpm"
-- Do a find in path on all our files for "github.com/droolsjbpm")
-- Which webapps reference it?
--- jenkins
--- jira
--- www.openhub.net
--- gitter
--- stackoverflow
--- google forums / mailing lists
--- ...
- Set a date when you'll be moving the first repository.
-- Clearly communicate on all channels to let everyone know. This includes:
--- Public mailing lists and fora: Drools, OptaPlanner, jBPM, ...
--- Internal mailing lists: sme-brms, pm lists, bsig, etc
--- IRC channel topics
--- Social media (Twitter accounts etc)
--- ...
- Clearly communicate:
-- What you'll do
-- When you'll do it
-- How strong the freeze is: Can they make local changes meanwhile? Will they lose the open PR's? How will this affect their forks and branches? Answer all these questions proactively, based on your experience. Cropped screenshots are good!
-- A recipe: What they need to do - step by step for dummies - after the merge is done.
-- Get someone to review this mail before it goes out.
- You can't overcommunicate this, but you can undercommunicate it. And there's always going to be 1 person who complains he wasn't told about it and it messes up his work.

Do it:

- You can do one repository at a time, or do multiple at the same time.
-- I'd recommend to start with just 1 to get a feel for it.
- Do them in reverse order of the repository-list.txt!
- DELETE THE OLD REPOSITORY. DO NOT COPY IT, BUT MOVE IT.
-- After the move, we want anyone that's trying to pull from droolsjbpm to clearly *fail* pulling, but without losing local changes.
-- Some people will not have read your mail, they need to fail when pulling, otherwise they'll find themselves asking in 5 months why we haven't done any changes in 5 months.
- In droolsjbpm, create a repository called all_repositories_have_moved_to_github_com_kiegroup and make sure it's on the top of the list of the droolsjbpm repositories. Add a link in it's readme.adoc. This is for people who follow dead links from stackoverflow etc.
- Migrations like this should really happen during the weekend to reduce the impact on the rest of the team, ask your manager to swap a weekday for a weekend day.


Anyway, that's my 2 cents (from my experience when moving svn to Git and splitting up the monastical build 5 years ago). Do this right and this will be almost a non-event (5 years ago it went pretty well on the engineering side, but less on the product side). Mess this up and this can be a disaster that will antagonize a lot of people...
