In July 2022, we started to phase out our first-generation app migration listeners (AppCloudMigrationListenerV1 and CloudMigrationListenerV1) in favour of DiscoverableListener.
One year has passed, and we have now reached our final deadline, which means that deprecated listeners may stop functioning. This would affect apps still using old interfaces, preventing them from participating in App Migrations.
Gladly, we are seeing good adoption indicators as well as reliability improvements thanks to the new library.
The upgrade process is straightforward and it’s documented on our public docs.
We also recommend partners periodically review what’s their minimum supported version declared on Marketplace: The Atlassian Marketplace REST API
