Migrate to Flow versus rebuilding automation
Key Takeaway
Use the Migrate to Flow tool for the workflow rules and record-triggered processes it supports. When the tool can't handle one, rebuild the logic by hand in Flow Builder or redesign it.
Salesforce stopped supporting Workflow Rules and Process Builder on December 31, 2025, so admins need to move that automation to Flow Builder. The Migrate to Flow tool converts many workflow rules and record-triggered processes into flows for you. Some features block or limit the tool. For those cases, the admin rebuilds the logic by hand in Flow Builder or redesigns it.
Why move to Flow Builder
As of December 31, 2025, Workflow Rules and Process Builder get no Salesforce customer support or bug fixes. Active rules and processes keep running. Salesforce still recommends migrating them to Flow Builder as soon as possible.
Flow Builder is the main automation tool in Salesforce. Entry conditions let a flow run only when certain conditions are met, which improves performance. The "Fast Field Updates" option makes flows run almost 10 times faster than workflow rules and processes.
