[Autobase 2.6](https://github.com/vitabaks/autobase/releases/tag/2.6.0) introduces a **blue-green deployment** workflow that allows you to prepare a fully upgraded cluster in advance and switch traffic with near-zero downtime.
Instead of upgrading your production cluster directly, you can: - deploy a clone of the cluster (Patroni standby cluster), - synchronize data using physical replication, - automatically upgrade PostgreSQL on the target cluster, - convert it into a logical replica, - and continue receiving live changes from production until switchover. When ready — switch traffic in seconds with near-zero downtime! If needed, rollback is just as fast and without data loss due to reverse logical replication. See the full list of changes in the [release notes](https://github.com/vitabaks/autobase/releases/tag/2.6.0) ## About Autobase **Autobase for PostgreSQL®** is an open-source alternative to cloud-managed databases (DBaaS). It empowers you to deploy and manage production-grade, highly available PostgreSQL clusters with ease. Autobase simplifies operations, reduces infrastructure costs, and brings powerful automation to your team — even without deep DBA expertise. Automate deployment, failover, backups, restores, upgrades, scaling, and more — eliminating the need for manual database management. Website: [https://autobase.tech](https://autobase.tech)
