+# Migrate
+
+## Mainnet
+
+Migrations on mainnet have to go through governance. Once the guardians sign the
+upgrade VAA, the contract can be upgraded by submitting the signed VAA to the
+appropriate contract. For example, to upgrade the token bridge on mainnet,
+in `wormhole/clients/token_bridge/`:
+
+``` sh
+node main.js terra execute_governance_vaa <signed VAA (hex)> --rpc "https://lcd.terra.dev" --chain_id "columbus-5" --mnemonic "..." --token_bridge "terra10nmmwe8r3g99a9newtqa7a75xfgs2e8z87r2sf"
+```
+
+## Testnet
+
+
+For example, to migrate the token bridge to 37262, run in `tools/`:
+
+``` sh
+node migrate_testnet.js --code_id 37262 --contract terra1pseddrv0yfsn76u4zxrjmtf45kdlmalswdv39a --mnemonic "..."
+```
