  The 2.0 upgrade is primarily ergonomic and should not result in any infrastructure changes.
  +#### Before you upgrade
  +
  +SST no longer need to deploy a debug stack to support [Live Lambda Development](./live-lambda-development.md). You can remove the debug stack by going to your AWS CloudFormation console. Find the stack named `{stageName}-{appName}-debug-stack`, where `{stageName}` is the name of the stage, and `{appName}` is the name of your SST app. And remove the stack.
  +
  #### Packages
  1. SST is now a monorepo, remove all packages referencing `@serverless-stack/resources` `@serverless-stack/cli` `@serverless-stack/node` and `@serverless-stack/static-site-env`. Install the `sst` package
