+## Upgrade to testnet stage2
+
+### Prerequisites
+
+* Testnet stage2 genesis file and peer node address
+
+* Mnemonic from the [wallet](https://wallet.laconic.com)
+
+* Have a testnet stage1 node running
+
+### Setup
+
+* Clone / pull the stack repo:
+
+  ```bash
+  laconic-so fetch-stack git.vdb.to/cerc-io/testnet-laconicd-stack --pull
+  ```
+
+* Clone / pull the required repositories:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/testnet-laconicd setup-repositories --pull
+
+  # If this throws an error as a result of being already checked out to a branch/tag in a repo, remove the repositories and re-run the command
+  ```
+
+* Build the container images:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/testnet-laconicd build-containers --force-rebuild
+  ```
+
+  This should create the following docker images locally with latest changes:
+
+  * `cerc/laconicd`
+
+### Create a deployment
+
+* The existing deployment used for stage1 can be used for stage2
+
+* Copy over the published testnet genesis file (`.json`) to data directory in deployment (`testnet-laconicd-deployment/data/laconicd-data/tmp-stage2`):
+
+  ```bash
+  # In dir where stage1 deployment (`testnet-laconicd-deployment`) exists
+  TESTNET_DEPLOYMENT=$(pwd)/testnet-laconicd-deployment
+
+  # Example
+  mkdir -p $TESTNET_DEPLOYMENT/data/laconicd-data/tmp-stage2
+  cp genesis.json $TESTNET_DEPLOYMENT/data/laconicd-data/tmp-stage2/genesis.json
+  ```
+
+* Run script to reset node data and upgrade for stage2:
+
+  ```bash
+  cd ~/cerc/testnet-laconicd-stack
+
+  docker run -it \
+    -v $TESTNET_DEPLOYMENT/data/laconicd-data:/root/.laconicd \
+    -v ./ops/stage2:/scripts \
+    cerc/laconicd:local bash -c "/scripts/upgrade-node-to-stage2.sh"
+
+  cd $TESTNET_DEPLOYMENT
+  ```
+
+### Configuration
+
+* Inside the `testnet-laconicd-deployment` deployment directory, open `config.env` file and set following env variables:
+
+  ```bash
+  CERC_CHAIN_ID=laconic_9000-2
+
+  # Comma separated list of nodes to keep persistent connections to
+  # Example: "node-1-id@laconicd.laconic.com:26656"
+  # Use the provided node id
+  CERC_PEERS=""
+
+  # A custom human readable name for this node
+  CERC_MONIKER=
+  ```
+
+### Start the deployment
+
+```bash
+laconic-so deployment --dir testnet-laconicd-deployment start
+```
+
+See [Check status](#check-status) to follow sync status of your node
+
+See [Join as testnet validator](#join-as-testnet-validator) to join / rejoin as a validator using laconicd CLI
+
+### Clean up
+
+* Same as [Clean up](#clean-up)
+
 ## Troubleshooting
 
 * If you face any issues in the onboarding app or the web-wallet, clear your browser cache and reload
