Ever since Facebook announced it would discontinue its Parse service starting in 2017, developer tool companies have been scrambling to offer migration paths. While developers can run their own Parse Server, one of the biggest benefits of Parse was that developers didn’t need to run software for their mobile (and non-mobile) backends.
It still requires code changes, of course, but allows the user’s perspective to be a seamless transition. The first time a Parse user logs in, their account is migrated to the Auth0 backend. Next time, only Auth0 is called.
To use this migration path, devs should start soon, because you’ll want plenty of time for migration and Parse goes away January 28, 2017.
