Deprecated legacy SDK channel not updated to Scene Graph before January 1, 2019.
Channels will likely have at least a year from January 1, 2019 before the deprecated components are fully removed. This should give developers enough time to update the channel. When the components are officially removed, legacy channels will still be found in Search and in the Channel Store, but it will no longer load. Channels that are found to not load are eventually removed from the platform, but this process will not immediate as we are not actively looking for broken channels.
Please note that after January 1, 2019, channels built or updated using the legacy SDK will not pass certification and will not be published.
