The following sections explain which adjustments must be made to migrate from Camunda Cloud 1.1.x to 1.2.0 for each component of the system.
We identified an issue in our recent release of Zeebe 1.2 related to our concept of processing on followers. Version 1.2.0 and 1.2.1 are affected by a bug, resulting in an inconsistent state (#8044).
Therefore we recommend waiting to update to 1.2 until we have released the next patch release to mitigate this issue.
With Operate 1.2, a new feature was introduced to quickly navigate a call activity hierarchy. This feature is only available for instances started after the version 1.2 update. Older instances will not expose this information to the user.
