+# Migrating Connected Systems to SLE 2023-07 or later
+
+The current release is introduces a breaking change regarding the systems connectivity that affects releases prior to SLE 2023-07. The saltmaster service which manages the connectivity with the client systems has been replaced with a new implementation that disconnects all connected clients. Complete the following steps to re-approve and re-connect all previously connected clients.
+
+## Prior to upgrading to SLE 2023-07
+
+The old salt-master uses a pair of RSA keys to secure communication. The public key is already cached on all
+accepted clients. You must persist these keys between all versions of SLE, so the client systems do not reject the new salt-master
+that would have a different public key.
+
+1. Open a terminal to the current 'saltmaster-0' pod.
+2. Navigate to '/etc/salt/pki/master'
+3. Make a note of the master.pem (private key) and master.pub (public key) values.
+4. Set these values to the secrets definition object of the saltmaster chart in the top level secrets values yaml file. Make sure
+you use the '|' indicator because these are multiline strings. See more info here: <https://yaml-multiline.info/>
+
+The updated chart will create a Kubernetes secret using these two keys.
+
+## Post SLE Upgrade
+
+After the upgrade, all previously connected (green/orange systems) will be shown as **Disconnected**. Additionally, all these clients will also be shown in the **Pending systems** list. You can use the [Jupyter Notebook](./NewSaltMaster-SystemsMigration.ipynb) provided to automate system approval. This notebook will add systems to the workspace they were previously a member of. The user who runs the notebook must have the **Add systems** privilege in all the necessary workspaces.  
+
+1. Ensure all systems are disconnected and appear in the pending systems list.
+1. Upload **NewSaltMaster-SystemsMigration.ipynb** to JupyterHub.
+1. Identify a single system to validate the notebook operation.
+1. Override `managed_systems_to_approve` with its id and workspace. The notebook already
+contains this line, we only need to uncomment it and add the id and workspace:
+
+    ```python
+    managed_systems_to_approve = [{"id":"Precision_5570--SN-GPP8WT3--MAC-15-75-5B-DC-5F-BB","workspace":"846e294a-a007-47ac-9fc2-fac07eab240a"}]
+    ```
+
+1. Run the notebook and check the output. It should say that one system was approved.
+
+    ```python
+    Approving 1 batches of 50 systems
+    Approving 1 minions, batch: 1
+    [{'action': 'ACCEPT',
+    'id': 'Precision_5570--SN-GPP8WT3--MAC-15-75-5B-DC-5F-BB',
+    'key': None,
+    'workspace': '846e294a-a007-47ac-9fc2-fac07eab240a'}]
+    Manage Systems Keys Result: {} {'error': None}
+    ```
+
+1. Validate that the selected system is now connected (green).
+
+    **Note** Misconfiguration of the RSA keys for the salt master may cause this operation to fail. Review the new secrets and [logs on the system](https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000kGcSSAU&l=en-US)
+1. After connecting this single system, you can now uncomment the override of `managed_systems_to_approve` and run the notebook again.
+
+    ```python
+    # managed_systems_to_approve = [{"id":"Precision_5570--SN-GPP8WT3--MAC-15-75-5B-DC-5F-BB","workspace":"846e294a-a007-47ac-9fc2-fac07eab240a"}]
+    ```
+
+    **Note** The new run will re-approve all the systems in batches of 50 (this can also be modified in the notebook)
+1. Ensure all the previously connected clients are connected (green).
+1. [Optional] Delete the PVCs and volumes used by the old implementation. PVC names: `saltmaster-pillar-saltmaster-0` and `saltmaster-pki-saltmaster-0`.
