Hi everyone. This is an announcement for a change in the coming migration for our issue system.
I first thought we'd keep our issue system available during migration (and made a plan not to introduce downtime). However, there are a couple of suggestions and discussions in an issue <https://github.com/apache/lucene-jira-archive/issues/4> to completely non-writable both Jira and GitHub until the migration is completed to avoid any inconsistency or accidents; I generally agree with that for safety. Allowing downtime, the migration will proceed as follows: 1. Make both Jira and GitHub read-only for everyone except for the accounts that are used in the migration. We'd need to forbid PRs as well as issues since pull requests are just special issues in GitHub. 2. Start migration. This would take ~72 hours. 3. Make GitHub issues and PRs writable once the migration is completed. 4. Make Jira writable (only for committers or me, if possible). 5. Add each Jira issue a comment saying "This was moved to GitHub [URL]". 6. Make Jira read-only. The arrangements in detail will be determined with the infra team, but I first wanted to share the change with devs. The plan is not fixed yet, and there are still uncertainties in access control to me. If you have objections or suggestions about the plan, please reply to this mail. Thanks, Tomoko
