# Workflow Field Updates
**Workflow Rules (along with Process Builders) are now on a deprecation / End-of-Life plan. Existing Workflow Rules will continue to operate for the foreseeable future, but in the near future (Winter 23) Salesforce will begin to prevent creating new Workflow Rules. Establish a plan to migrate to Flows, and create any new automation using Flow Builder.**
