We settled on a **logical-replication migration to PostgreSQL 16 using `pglogical`**, rather than `pg_dump`/restore, because minimizing downtime was important.

Plan:
- Configure the **PostgreSQL 13 primary as the pglogical publisher**.
- Sync a **new PostgreSQL 16 subscriber** in parallel.
- Perform the final cutover during a **Sunday 02:00 maintenance window**.

The publisher and subscriber had already been configured and were syncing. This was in @session:default/20260810_091500_aa11bb.

We settled on a **logical-replication migration using `pglogical`** to minimize downtime:

- Upgrade from the **Postgres 13 primary to a new Postgres 16 cluster**
- Configure the existing cluster as the **publisher**
- Configure the new Postgres 16 cluster as the **subscriber**
- Let it sync continuously, then perform the cutover during a **Sunday 02:00 maintenance window**

The setup was noted as already in progress: the pg13 publisher and pg16 subscriber were configured and syncing. See [the migration conversation]( @session:default/20260810_091500_aa11bb ).

We settled on a **logical-replication migration using `pglogical`** rather than `pg_dump`/restore, to minimize downtime:

- **Source:** PostgreSQL 13 primary configured as the `pglogical` publisher
- **Target:** New PostgreSQL 16 server acting as the subscriber
- **Cutover:** Sunday at **02:00** during the maintenance window
- The new PostgreSQL 16 instance was already syncing from the existing primary.

We settled on a **logical replication migration using `pglogical`** for near-zero downtime:

- Migrate from the **Postgres 13 primary** to a new **Postgres 16** instance.
- Configure the existing cluster as the **publisher** and the new instance as the **subscriber**.
- Let the subscriber sync, then perform the cutover during a **Sunday 02:00 maintenance window**.

The setup was recorded as complete: the pg13 publisher and pg16 subscriber were syncing. See [the migration conversation](@session:default/20260810_091500_aa11bb).
