I am looking at the best approach to export Virtuemart 3 custom fields and importing them into a new Virtuemart 4 installation to prepare for a product migration. I am aware that I should have data like categories and manufacturers imported as well, but that is already done.
My thoughts about the export and import are the following:
- Export VM3 custom fields with virtuemart_custom_id to keep the same structure as the old shop (see export attachment).
- Remove custom fields that depend on a old plugin in the CSV.
- Import into VM4
I tried this approach and as you can see in the attached log, the custom fields are updated. However, taking a look in the backend there a no special fields available at all.
What could be the issue. Am I missing something in my CSV? Or should I perform some kind of initialization after import?
