Yes it surely is. I am not sure what happens with existing data (in case of same data field numbers) but I already transferred a huge amount of data (142 fields) from one shop to another.
The shop moved so there was no field data yet in the PPOM plugin in the shop at the new website.
What I did was:
Export:
- Go to PPOM fields under the WooCommerce section in WordPress admin
- Changed the view to 100 entries
- Select the first 100 fields with the checkbox
- Export the first 100 fields to .csv
Import:
- Go to PPOM fields under the WooCommerce section in WordPress admin
- Click on: Import Meta
- Select export . csv file
- Import the first 100 fields
And repeat for remaining fields. This worked perfect for me.
