+Upgrade Charmed MLflow 2.1 to 2.15
+==================================================
+
+This guide describes how to upgrade Charmed MLflow version 2.1 to 2.15. 
+
+Prerequisites
+-------------
+
+This guide assumes:
+
+* You have deployed MLflow version 2.11.
+* You have Command Line Interface (CLI) access to the machine where the Juju controller is deployed. All commands in this guide are executed from it.
+
+.. tip:: 
+    Before proceeding, you might want to backup MinIO data including your experiments and models. See :ref:`backup` for more details.
+
+Upgrade dependencies
+---------------------
+
+Charmed MLflow 2.15 requires:
+
+1. `MicroK8s <https://microk8s.io/>`_ version 1.29 or higher.
+2. `Juju <https://juju.is/>`_ version 3.4.
+
+If you do not meet these requirements, please upgrade these dependencies. 
+See `MicroK8s upgrade <https://microk8s.io/docs/upgrading>`_ 
+and `Juju upgrade <https://juju.is/docs/juju/upgrade-your-juju-deployment>`_ respectively for more details.
+
+Upgrade MLflow bundle
+----------------------
+
+To upgrade the MLflow bundle charms from 2.11 to 2.15, run the following commands:
+
+.. code-block:: bash
+
+    juju refresh mlflow-minio --channel=ckf-1.9/stable
+    juju refresh mlflow-server --channel=2.15/stable
+
+Upgrade resource dispatcher
+--------------------------------------
+
+Only if you are running MLflow within Kubeflow, you must upgrade your `resource dispatcher <https://github.com/canonical/resource-dispatcher>`_ deployment. 
+
+.. note::
+    MLflow 2.15 works only with resource dispatcher version 2.0/stable.
+
+To upgrade your resource dispatcher, do the following:
+
+.. code-block:: bash
+
+    juju refresh resource-dispatcher --channel=2.0/stable
