Hi @Anonymous,
Most every time I have data from a dev environment that I need to migrate to production I usually do the following:
1. Go to https://admin.powerplatform.microsoft.com and click on "Environments"
2. In the Production environment, click on Settings
3. Expand the Templates and you will see data import templates

4. Export the data from your development environment and populate into the import template from the development data. Note, do not populate the columns A-C since this is keys for your development rows.
5. In the Views page for the entity, import the data to the production environment through the Import from Excel
Overall I have migrated a large number of tables quickly with this approach and it is simple.
Hopefully this helps. Please accept if answers your question or Like if helps in any way.
Thanks,
Drew
to another environment I usually just utilize Excel the data template for the table / entity from the production environment and then export the data from the dev environment and put this into the
