# Docker upgrade

First, create the new volume to new version

```
docker volume create postgres-XX
```

In `docker-compose` add in volume the section with the new volume.
In service duplicate the postgres section, append version

start the new empty database, import new data like:

```
docker-compose exec --user postgres -i postgres16 pg_dumpall | docker-compose exec --user postgres -T postgres psql
```

Then remove old DB in __docker-compose.yml__, clean volume etc.
