The first step in migrating your subscriptions from Recharge to Appstle is obtaining the proper CSV exports from Recharge.
If you aren't familiar with Recharge's export process, please take a look at their documentation, with detailed instructions on how to operate their Export Builder.
Once you're ready to export the data from Recharge, please make sure your exports contain all of the necessary information below:
Subscriptions - All
Charges Queued (up to 1 year in the future)
Customers - Shipping Addresses
