Upgrade

If you have compatibility issues when you try to upgrade Domino, upgrade fleetcommand-agent. See the Release Notes for a full list of compatible fleetcommand-agent versions for the different versions of Domino.

Pull fleetcommand-agent version to install from quay.io:
```
docker pull quay.io/domino/fleetcommand-agent:v54
```
Create a copy of your domino.yml configuration file. Name it something like domino-orig-<date>.yaml, to indicate when you modified the configuration.
To generate a new domino.yml configuration file, run the initialization command through the upgraded fleetcommand-agent file. This ensures that you have a configuration schema that conforms to this version of fleetcommand-agent.
```
docker run --rm -it -v $(pwd):/install quay.io/domino/fleetcommand-agent:v54
  init --file /install/domino.yml
```
Copy custom values from your original configuration into the new file.
When the upgrade is complete, run fleetcommand-agent from the install process and change the spec.containers.image value to quay.io/domino/fleetcommand-agent:v54.
