+## Upgrade Commands
+
+This document provides commands to upgrade existing Mojaloop installations. It assumes that Mojaloop is already installed using Helm.
+
+### Upgrade to v17.0.0
+
+1. Upgrade the backend dependencies
+```bash
+helm upgrade backend mojaloop/example-mojaloop-backend --namespace ${NAMESPACE} --version v17.0.0 -f ${VALUES_FILE}
+```
+2. Install the mojaloop services
+```bash
+helm install moja mojaloop/mojaloop --namespace ${NAMESPACE} --version v17.0.0 -f ${VALUES_FILE}
+```
+
+#### Testing the upgrade scenario from v16.0.0 to v17.0.0
+
+1. Install backend dependencies v16.0.0 with persistence enabled (need to create databases manually since the initDb scripts will not run)
+```bash
+helm --namespace ${NAMESPACE} install ${RELEASE} mojaloop/example-mojaloop-backend --version 16.0.0  -f ${VALUES_FILE}
+```
+2. Install the mojaloop services v16.0.0 and run tests to create data in databases
+```bash
+helm --namespace ${NAMESPACE} install ${RELEASE} mojaloop/mojaloop --version 16.0.0  -f ${VALUES_FILE}
+```
+3. Uninstall the mojaloop services
+```bash
+helm delete ${RELEASE} --namespace ${NAMESPACE}
+```
+4. Upgrade the backend dependencies to v17.0.0 (This will upgrade mysql/Kafka/MongoDB versions)
+```bash
+helm --namespace ${NAMESPACE} upgrade ${RELEASE} mojaloop/example-mojaloop-backend --version 17.0.0  -f ${VALUES_FILE}
+```
+5. Install the mojaloop services v17.0.0 (This will run the knex migrations to upgrade the database schemas)
+```bash
+helm --namespace ${NAMESPACE} install ${RELEASE} mojaloop/mojaloop --version 17.0.0  -f ${VALUES_FILE}
+```
+6. Run the GP Tests
+```bash
+helm test ${RELEASE} --namespace=${NAMESPACE} --logs
+```
