Heyo! I work on this process @ Stormpath / Okta. It will largely be an automated process in two stages: export then import. You'll be able to do multiple exports / imports, so you can continue running in production on Stormpath while testing on Okta. The flow is pretty simple: export your Stormpath data (no interruption), import to Okta, test, then when you're ready to go 'live': export from Stormpath again and pause servers, import to Okta again (to get new things added), and switch code to run against Okta. We'll be releasing more details soon.
