Copy product metafield to another metafield

To copy a product metafield to another metafield, you can use the "Update product metafield" action in Shopify Flow.

According to the actions.json document, the "Update product metafield" action has the following fields:

• Metafield namespace: Required. A metafield namespace is a container for a group of metafields.
• Key: Required. A key is an identifier for the metafield value.
• Value: Required. The value is the information to be stored in the metafield.

You can use this action to copy the value from one metafield to another by setting the "Value" field to the value of the original metafield.

For example, you can use the "Run code" action to get the value of the original metafield and then use that value in the "Update product metafield" action.

Please refer to the actions.json document for more information on how to use the "Update product metafield" action.

Additionally, you can use a template like "Update a product metafield if a product tag has a certain prefix" (https://admin.shopify.com/apps/flow/editor/templates/908286d2-3e4c-4d9d-8e28-3cf9b12db4df) as a starting point and modify it to suit your needs.

Remember to replace the namespace and key in the "Update product metafield" action with the actual namespace and key of the metafield you want to copy to.

Please note that the available documents do not provide a step-by-step guide on how to copy a product metafield to another metafield, but they do provide the necessary information to achieve this using the "Update product metafield" action.
