If you have the team-based development option, you can enable version control for a new or existing repository. A versioned repository can store multiple versions of objects. If you enable version control, you can maintain multiple versions of an object, control development of the object, and track changes. You can also use labels and deployment groups to associate groups of objects and copy them from one repository to another. After you enable version control for a repository, you cannot disable it.
When you enable version control for a repository, the repository assigns all versioned objects version number 1, and each object has an active status.
