 The process is very similar with 2.1.

+### 4. Existing DAOs will need to migrate from v2 to v3.
+
+Assumptions:
+- we are the trying to upgrade `amber.sputnik-dao.near` from v2 to v3
+- we have the account id `ctindogaru.near`
+
+1. Open a bash terminal and login to your near account:
+
+```bash
+export NEAR_ENV=mainnet
+```
+
+```bash
+near login
+```
+
+2. Clone the sputnik repo and go to the v3 snapshot of the code.
+
+```bash
+git clone https://github.com/near-daos/sputnik-dao-contract && cd sputnik-dao-contract
+```
+
+```bash
+git checkout 596f27a649c5df3310e945a37a41a957492c0322
+```
+
+3. Store the DAO code in your DAO.
+
+```bash
+BYTES='cat sputnikdao2/res/sputnikdao2.wasm | base64'
+```
+
+```bash
+near call amber.sputnik-dao.near store_blob $(eval "$BYTES") --base64 --accountId ctindogaru.near --gas 100000000000000 --amount 10
+```
+
+After running the command from above, you should get the following code hash in return: `GUMFKZP6kdLgy3NjKy1EAkn77AfZFLKkj96VAgjmHXeS`. If your result differs from `GUMFKZP6kdLgy3NjKy1EAkn77AfZFLKkj96VAgjmHXeS`, do not proceed further as you could harm your DAO. Ask for help on the telegram group: `SputnikDAO v2.0`.
+
+4. Create an upgrade proposal for your DAO.
+
+Run the following command:
+```bash
+near call amber.sputnik-dao.near add_proposal '{"proposal": {"description": "Upgrade DAO to v3 version", "kind": {"UpgradeSelf": {"hash": "GUMFKZP6kdLgy3NjKy1EAkn77AfZFLKkj96VAgjmHXeS"}}}}' --accountId ctindogaru.near --amount 1
+```
+
+5. Approve the proposal.
+
+Everyone from the DAO should go to `https://app.astrodao.com/dao/amber.sputnik-dao.near/proposals` and approve the proposal.
+
+6. Once the proposal get approved, the upgrade will take place.
+
+7. Now that the upgrade is complete, remove the code from your DAO.
+
+```bash
+near call amber.sputnik-dao.near remove_blob '{"hash": "GUMFKZP6kdLgy3NjKy1EAkn77AfZFLKkj96VAgjmHXeS"}' --accountId ctindogaru.near --gas 100000000000000 --amount 10
+```
+
+7. Congrats! You're now using the DAO v3.
