+# Transition your stake from phase-1 to phase-2 through CLI

+<!-- TODO -->

+>  used for Phase-1. All stakers are required to transition their stakes to this 
+>  program to participate in Phase-2.

+- [Prerequisites](#prerequisites)
+- [1. Setup](#1-setup)
+- [2. Transition your stake](#2-transition-your-stake)
+
+## Prerequisites
+
+To transition your stake from phase-1 to phase-2, you need to have the following:
+-  Global parameter file as seen here https://github.com/babylonlabs-io/networks/blob/main/bbn-5/parameters/global-params.json that were used in phase-1
+-  The Bitcoin block height in which your staking transaction was included
+- Your `btc-staker` binary setup and running inclusive of the btc staker config 
+  properly setup
+
+## 1. Setup 
+
+First, you need to run the upgrade setup which configures the environment and 
+runs necessary upgrade procedures:
+
+```bash
+cd deployments/local
+make bbn-upgrade-v1
+```
+
+Next, you need to dump the default configuration file. This creates a template 
+that you'll customize with your specific values (like your Bitcoin block height 
+that your staking transaction was included in, wallet credentials, 
+and network details):
+
+```bash
+stakercli admin dump-config
+```
+
+This will create a `config.json` file in your current working directory. 
+You'll need to modify this file with your specific settings before proceeding.
+
+Finally, start the `btcstaker` daemon which will manage your connections to both 
+Babylon and Bitcoin nodes, monitor transactions, and handle the staking process:
+
+```bash
+stakercli admin start
+```
+
+## 2. Transition your stake
+
+After setting up the configuration file and starting the `btcstaker` daemon, 
+you can proceed to transition your stake from Phase-1 to Phase-2 using the 
+following command. We use the `global_parameters.json` file that you should 
+already have created as stated in the prerequisites.
+
+```shell
+stakercli daemon stake-from-phase1 <global-parameters-file> \
+    --staking-transaction-hash <your-phase1-tx-hash> \
+    --staker-address <your-btc-address> \
+    --tx-inclusion-height <block-height>
+```
+
+parameters:
+- `global-parameters-file`: The path to the global parameters file.
+- `your-phase1-tx-hash`: The original hash of your phase-1 staking transaction.
+- `your-btc-address`: BTC address of the staker in hex
+- `block-height`: The block height at which your staking transaction was 
+    included.
