UPDATE: fix released. Please update to Platform Version 2.3.5.103 BEFORE attempting to run the migration on the C-8 hub, as well as the old hub, then create a new cloud backup to be used to migrate to the C-8 hub
Our engineers have identified an issue with the C-8 migration and are currently working on releasing an update to correct the problem.
Please postpone the migration this morning, until the next update is released.
Thank you for your patience and understanding.
