Delete and rename limits for change sets
Key Takeaway
A change set can't delete or rename a component. You delete a component on the target org, and you rename it by deleting it there and then uploading the renamed component in a change set.
Change sets move components from one Salesforce org to another org, called the target org, but they can't delete or rename components. When you need to remove or rename something in the target org, you do part of the work by hand in that org. Knowing this limit helps you explain why a deployment did not remove or rename what you expected.
How to delete or rename a component
A change set only brings components into the target org, so removing or renaming a component has to happen another way.
If you need to delete a component...
Use the Web interface directly on the target org.
If you need to rename a component...
First, delete the component on the target org. Then upload the new, renamed component in a change set.
