Overview

This topic explains how to deprecate flags you no longer need.

​
About deprecating flags

When a flag is still being served to customers, but it is only being served in older or deprecated versions of your application, it may be time to deprecate it. Deprecating a flag hides it from the live Flags list without archiving or deleting it. You can restore a deprecated flag if you need it, or find it to reference or update its configuration later. Deprecating flags can simplify your Flags list, especially in situations where you have a long tail of customers using older versions of your applications. You can only deprecate flags that you use with client-side SDKs. Deprecated flags are still evaluated, just like live flags. If you are completely done with a flag, you should archive it instead. To learn more, read Archiving flags.

Deprecate flags

To deprecate a flag:
  1. Navigate to the Flags list and open the flag you wish to deprecate.
  2. Click the three-dot overflow menu in the right sidebar.
  3. Select Deprecate. The “Deprecate flag” dialog appears.
  4. The dialog shows you how the flag has been evaluated recently.
All flags exist in every environment for a project, but often only a few environments matter for your organization’s production processes. Deprecating a flag will remove it from the live Flags list for every environment in the project.
  1. Click Deprecate.
The flag is deprecated and removed from the live Flags list. You can find it in the deprecated Flags list. To learn more, read View and restore flags.
