Updated Schema Field Name - How to Delete Property with the Old Name

Hello! I updated a field name on my schema and saved a record to that field for a saved document so now I have properties for both the old and newly named field in that document. Is there a way to delete the property with the old name or would I have to delete the whole document? Thanks!

Never mind I just found the alert in Sanity studio that says "Found 1 unknown fields" where it allows you to unset it!

Exactly! Glad you found it 🙂
In case you run into this issue for a large number of documents in the future, there is another approach using a script instead. It’s slightly more technical but can prevent you from having to edit a large number of documents. I’ll just leave it here in case you ever need it:
