RE: How to deploy HR sandbox to production environment?
Hi Simon,
The best practice would be using the production environment as golden configuration environment; not the sandbox. Then before the go-live, you can first perform a database refresh from production to UAT for testing.
When this is all OK, you can go live. The data package import in production is intended to import data which was not part of the configuration. E.g. employees or open leave balances.
The best practice to use the production as golden config was also mentioned in the documentation you shared yourself. Now you have to check if there are data entities available to move all configuration from your sandbox to production, manually configure the production environment or a hybrid approach. I would recommend to do another UAT test again like outlined in the documentation to ensure the production is setup correctly.
