I have a content type Products which contains a groupX field for product documents. By an oversight I set a wrong storage for groupX field and content is stored as a part of #__content introtext. I would like to fix this and let the field content store in its correct db column, but the problem is that my client already submited more than 300 products (including the documents) and by changing of the storage ->the data will be lost.
So is there a reasonabe way (db process) to change the sotrage of groupX field without losing the content?
I tried to help myslef with SEBLOD Import / Export plugins but it seems the content of nested groupX fields is not exported.
