# Production Deployment

> Reference for the deprecated sqd prod command — legacy production deployment workflow now replaced by the slots-and-tags model with sqd deploy --tag prod.

`sqd prod` and the production aliases system are deprecated starting from `@subsquid/cli@3.0.0`. Zero downtime updates are now handled by the [slots and tags system](/en/cloud/resources/slots-and-tags). See also the [changelog](/en/cloud/reference/deployments-two-changelog) for a comparison between production aliases and the new system.
