I had to switch a dropdown field to a multiselect field. Previously the values were stored as integers (in catalog_product_entity_int) but now with multiselect I have to use varchar (catalog_product_entity_varchar).
I'm not sure how to move the data from one table to another with a data script so I would be glad if someone can provide me a possible solution or any thoughts on how to do it.
I googled already a bit but I guess I use the wrong search words..
Thanks in advance
