Custom Fields question - Can I update the "Name" of custom field without interrupting a fusion scenerio?

I have a use case where I need to update approximately 300 individual custom fields. The reason for the update is that we reference a team name to identify the team that created and is using the custom field. The team name has changed and needs to be updated

We are active fusion users and these fields might be referenced within a current fusion scenario. My goal is to make sure that if I update a field NAME, it won't upset/break an existing fusion scenario.  My understanding is that fusion reads a field ID number, not the actual name, I want to make sure this is true before I make any edits to custom fields. Thanks in advance for reviewing this
