If the deployment to the main network requires review, do I need to review again if I need to upgrade and update the smart contract after I pass the first review?

Hello,

Those links might help you.  
The testnet redeployment need to be handle by the DapperLabs team ==\> [Testnet Deployment Guidelines - Flow Documentation](https://docs.onflow.org/dapp-development/testnet-deployment/#redeploying-your-application)  
On mainnet is the same produce as 1st deployment ==\> [Mainnet Deployment Guidelines - Flow Documentation](https://docs.onflow.org/dapp-development/mainnet-deployment/#iterating-on-mainnet)

Best,  
Lionel

In the near future we are going to support permisioneless deployments of contracts with [Stable Cadence](http://forum.flow.com/t/the-path-to-stable-cadence/2702) so stay tuned.
