In InformaCast Fusion 14.17.1, we significantly improved the way in which on-premises servers pull and sync resource data from the cloud, making it faster and more resilient. To allow for this improvement, we used the upgrade process to migrate data from the older structure to a new one.

Unfortunately, a flaw in the migration’s logic made the assumption that data for Cisco IP phones for Unified CM would be present on all on-premises servers, even for customers not licensed for them. This assumption caused the migration to fail, and because the migration had to be performed before synchronization could start, the servers were unable to sync data correctly.

Realizing the severity of the situation, we worked quickly to release version 14.17.2, which removed the erroneous assumption from the migration process. We will examine our internal testing processes in the coming weeks to ensure that we consistently test future migrations against a range of data and differing environments. We deeply apologize for the impact on our customers, and we strive to do better.
