Migrate to a different cloud provider or region

Any Aiven service can be relocated to a different cloud vendor or region. This is also valid for PostgreSQL® where the migration happens without downtime. Cloud provider/region migration features mean that you can relocate a service at any time, for example to meet specific latency requirements for a particular geography.

To migrate a PostgreSQL service to a new cloud provider/region

  1. In your service, click Service settings from the sidebar.
  2. In the Cloud and network section, click Actions > Change cloud or deployment model.
  3. In the Cloud section, select a cloud provider and region, and click Migrate.

The PostgreSQL cluster will enter the REBALANCING state, still serving queries from the old provider/region.

note

You can check the service's state at the top of the service's page, just below the service's name.

New nodes will be added to the existing PostgreSQL cluster residing in the new provider/region and the data will be replicated to the new nodes. Once the new nodes are in sync, one of them will become the new primary node and all the nodes in the old provider/region will be decommissioned. After this phase the cluster enters in the RUNNING status, the PostgreSQL endpoint will not change.

note

You can check the nodes' availability at the top of the service's page, just below the service's name.

tip

To have consistent query time across the globe, consider creating several read-only replicas across different cloud provider/regions
