You could use https://github.com/pods-framework/pods-convert for this. It’s a plugin that adds a new WP-CLI command that you can use to convert a pod to a new content type or content storage option.
For CPTs, converting from table-based storage to meta-based storage will bring over all of those fields from the table for each post (1 row per post) into the postmeta table (1 row per field value per post).
