Understand the flow of updating Application.

[ponikar]

Hi,
We recently raised a PR to update our existing app, Huddle01. We introduced new changes which contain a different data structure for credentials, a new authorization flow to verify user identity at Huddle01, and new API endpoints. Since we have existing users who are using the old version of the Huddle01 app in Cal.com, we wanted to know how this will affect them.

• Do they need to update the app? Will the app update automatically?
• How can we add backward compatibility support for old users?

If anyone has any insights, please share them with us.

Thanks,
Darshan

Hey @ponikar!
I'm here to assist you with any bugs, questions, or contributions you have. Let's tackle this together!

For the update of the Huddle01 app within Cal.com, here are some insights:

1. App Updates: Users typically need to update the app to access new features or changes. Cal.com uses push notifications and email notifications to inform users about updates or changes, which can prompt them to update the app manually ^[1][2]. Automatic updates depend on the platform and how the app is distributed (e.g., through app stores or direct downloads).

2. Backward Compatibility: Implementing backward compatibility involves ensuring that the new version of the app can still interact with data or systems used by the old version. While specific guidelines for backward compatibility aren't detailed in the available information, a common approach is to maintain support for old data structures and API endpoints alongside the new ones. This might involve versioning your API or providing a migration path for user data.

3. Migration Tools: Cal.com includes migration scripts to help transition users from an old app version to a new one. These scripts handle database schema changes and organizational migrations, ensuring a smooth transition without data loss ^[3][4][5][6].

For a seamless transition, consider implementing a strategy that includes notifying users about the update, providing clear instructions for updating, and ensuring that any critical data or functionality remains accessible during the transition.
