Hello,

I would like to convert some products on my site from the default product type to a custom product type without changing the product ids. I believe the following steps may work:

1. Create a custom product type and add the same fields that are attached to the default product type.
2. In table 'commerce_product' find the products I want to convert and change their type to the machine name of the custom product type.
3. Change the field bundle instance machine name for all of the fields of the products I would like to convert.

I am not quite sure what the implications would be for line items, i.e. products which have been previously purchased.

Or would it be easier to just recreate the products and then manually change the product ids in table 'commerce_product'? Does anybody have any thoughts or suggestions?

Thanks
