+# Pinning Versions
+
+## Old Version
+
+If you want to test rolling updates and upgrades to a new minor version, check out the *e90* sample:
+
+This sample installs version 9.0.1400 for testing. Because cluster node discovery changed with a newer jGroups version in nscale, the chart detects the older version and enables the legacy discovery mechanism so the Pod can find its peers on versions prior to 9.1.1200.
+
+```
+helm install \
+    --values samples/empty.yaml \
+    --values samples/demo.yaml \
+    --values versions/9.0.1400.yaml \
+    sample-e90 nplus/nplus-instance
+```
+
+## New Version Sample
+
+Some nscale versions are license compatible, meaning a 9.1 license file can also run nscale 9.0 software. But that is not always the case.
+
+So you may need to set individual licenses per instance:
+
+```
+kubectl create secret generic nscale-license-e10 \
+  --from-file=license.xml=license10.xml
+```
+
+Check that the license has been created:
+
+```
+# kubectl get secret | grep license
+nscale-license          Opaque              1      7d22h
+nscale-license-e10      Opaque              1      17s
+```
+
+Now install the instance:
+
+```
+helm upgrade -i \
+    --values samples/empty.yaml \
+    --values samples/demo.yaml \
+    --values versions/10.0.yaml \
+    --set global.license=nscale-license-e10 \
+    sample-e10 nplus/nplus-instance
+```
+
+## Probes
+
+Older versions might not work with the newer/current probes and may not start even though they are actually running. You can override the probes to match older versions, for example:
+
+```
+nappl:
+  probes:
+    livenessProbe:
+      httpGet:
+        path: /index.html
+        port: 8080
+      initialDelaySeconds: 60
+      timeoutSeconds: 3
+      failureThreshold: 5
+    readinessProbe:
+      httpGet:
+        path: /index.html
+        port: 8080
+      initialDelaySeconds: 60
+      timeoutSeconds: 3
+      failureThreshold: 5
+```
