On my dev site I have updated some custom fields. I want to import these updates to the live site.
On my dev site I did a test. I created the extra fields and then exported the field group as json.
I then deleted the new fields and saved the custom field group and tried to do an import.
I get an Warning Message message.
Import tool detected 1 field groups already exist and have been ignored:
How do we get around this problem.
OK I found the answer in another post. Sorry for not searching more thoroughly.

But just in case I will provide the answer links here.
Using Local JSON you can create a folder in your theme which will save JSON files and then when you upload these they can be synced.
Its worth noting that the sync field will not appear until it finds something to sync.
