Universal Containers has automated its deployment process using Metadata API.

Deploying unsupported components manually before/after deployment is the best way to address the issue of Metadata API not supporting all the components yet. Metadata API is a powerful tool for deploying changes between orgs, but it does not cover all the metadata types that are available in Salesforce. Some examples of unsupported components are email templates, dashboards, reports, and custom settings. These components need to be deployed manually by using other tools or methods, such as change sets, data loader, or manual configuration.
