# Editing a job Editing a job is very similar to adding a job ([more info here](/copytag-tags-to-metafields-app/creating-a-job.md)) with the same fields and options. The main differences are described below. ### Changing metafield name & key When you change `metafield name & key` the data from the previous metafield definition will be deleted. For example, if you have a definition for `myfield.category` and you change it to `myfield.type`, all of the data from `myfield.category` will be deleted and all tags will be copied to the new definition: `myfield.type`. ### Deleting a rule If you delete a rule for which you already have started the job, the data from the given metafield will be emptied. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
