GitHub user tuhaihe added a comment to the discussion: [Ideas] Description of backward-incompatible changes between Greenplum 6 and Cloudberry in the documentation.
+1 from me. I also noticed that we already have a `sys-admin/migration-and-upgrade.md` document. It might be a good place to start and evolve into a broader `Migration & Upgrade` section. The above content focuses primarily on `Greenplum 6 → Cloudberry` compatibility differences, but I can imagine additional migration and upgrade scenarios becoming relevant over time, for example: - Greenplum 6 → Cloudberry - Greenplum 7 → Cloudberry - Cloudberry 2.x (PostgreSQL 14) → Cloudberry 3.x (PostgreSQL 16) - Future Cloudberry major-version upgrades We may also eventually introduce tooling around upgrades (for example, a future `cbupgrade` utility), upgrade checklists, compatibility matrices, and migration best practices. With that in mind, it may make sense to group all `migration-` and `upgrade-related` content under a common section and add the `Greenplum 6 → Cloudberry` compatibility guide as the first major document there. Just a thought for future extensibility. GitHub link: https://github.com/apache/cloudberry/discussions/1816#discussioncomment-17261814 ---- This is an automatically sent email for [email protected].
