What steps should you take to deploy a new version of an API with minimal disruption to users?

Choosing to announce the new version before deprecating the old one ensures that users are informed about the changes and can prepare for the transition without experiencing disruption in their services. By proactively communicating the existence of the new version, users are given adequate notice to migrate to the new version, reducing the risk of confusion and support issues.

Additionally, this approach allows you to collect feedback from users based on their experiences with the new version, possibly leading to quick adjustments or additional support before the old version is phased out. Also, contacting the remaining users of the old API after the announcement illustrates a commitment to user support and facilitates the transition, enhancing user satisfaction.

This method ensures a smoother transition path and maintains a good relationship with users by keeping them informed and engaged throughout the process.
