Supported BDR upgrade paths v4
Upgrading within version 4
Beginning with version 4, EDB Postgres Distributed has adopted semantic versioning. All changes within the same major version will be backward compatible, lowering the risk when upgrading and allowing you to choose any later minor or patch release as the upgrade target. You can upgrade from any version 4.x release to a later 4.x release.
Upgrading from version 3.7 to version 4
Generally, we recommend you upgrade to the latest version 3.7 release, before upgrading to the latest version 4 release. You will have to be using 3.7.15 or later before upgrading to 4. See Upgrading within from 3.7 in the 3.7 documentation for more information. After upgrading to 3.7.15 or later, the following upgrade paths are possible.
| From version | To versions (range) |
|---|---|
| 3.7.15 | 4.0.2 to 4.2.1 |
| 3.7.16 | 4.0.2 to 4.2.1 |
