Self migration of data and cards can be easily done by following the steps given here.
The prerequisites are
- Complete your Chargebee site setup. Try out a few mock transactions to test and ensure the flow works as expected.
- Stop taking new sign ups through your existing billing platform. Take them in through Chargebee Live site.
- Ensure the 3rd party applications you are using won't be affected by the import.
Test the import once by importing the data to your Chargebee Test site using the same steps below. Log in to your Test site and check if the imported data is as expected. You can then clear your Test site and perform Live site import.
