---

The upgrade process for the latest 4.2.1.9 version of OpenIAM is similar to any other upgrade process, except several steps.

The common process is described in the document by this [link](1-upgrade-4207). Specific steps for OpenIAM version 4.2.1.9 are given below.

1. In 4.2.1.9 we've updated the RabbitMQ queue types to be resilient for HA.  This means that you must perform the following manual steps after upgrading. Once setup.sh is completed run the following commands
```
docker rm $(docker ps -a -q) -f
docker volume ls | grep rabbitmq
docker volume rm <all from the above ouptut>
```

2. Run `./startup.sh`

3. Wait for the containers to fully startup and then the application will be ready for use.

**Note:** Please note that you **_must_** update connector if you use newer versions of the product. It is recommended to use the latest connector version. All .NET/PS connectors versions as at 5.24.0.0 version are backward compatible, hence updating it will not disrupt operation of OpenIAM versions 4.2.0 and higher.
