# Upgrade Trilio

Starting Trilio for Openstack 4.0 does Trilio for Openstack allow in-place upgrades.

The following versions can be upgraded to each other:

| Old             | New               |
| --------------- | ----------------- |

The upgrade process contains upgrading the Trilio appliance and the Openstack components and is dependent on the underlying operating system.
