+
+## Upgrade Timeline

+## Upgrade to BC Node v0.10.22 Before Hardfork

+

+
+1) Download the new v0.10.22 binary and replace the previous version.
+
+2) Download the new config
+   file [app.toml](https://github.com/bnb-chain/node/releases/download/v0.10.22/mainnet_config.zip) to replace the
+   previous version or add the following under the [upgrade] module of `app.toml`.
+
+```toml
+SecondSunsetHeight = 378062790
+```
+
+3) Stop the bnbchaind process and restart it with v0.10.22.
+
+```shell
+service bnbchaind restart
+```
+
+## Key Highlight
+
