Managing Products

Converting Products into Product Variants

Create the necessary attributes and the attribute values.

Each product.template record also automatically creates a product.product record (variant), even if no variants are created explicitly.

You may want to create a new product template with  the  corresponding  variants , then go to the corresponding newly created product variants and export them to  see  the  External  ID  of  the  corresponding  product  template and the  fields  for  the  attribute  values .

Also export the product variants of the old product templates. Then in the  product  variant  records  replace the External ID of the product template with the External ID of the newly created product template,  add the  attribute  fields  and  reimport  the  product  variants.

Then delete  the  newly created  product.product  records  of  the  new  product  template.  Maybe it works.

But make a database backup before!
