Verify Custom Document Workflow Compatibility with Publication in Channel Manager
Bloomreach Experience Manager 12.4 introduces document publication from within the Channel Manager. If your implementation project uses a custom document workflow, you must validate that the publication options in the Channel Manager don't break that workflow. In principle, the Publish button only appears if there is an entry "publish" with value "true" in the workflow hints. If you implemented a custom workflow such that the "publish" entry is present in the hints, but the Publish option is hidden from the UI by some other customisation, then your project cannot be upgraded. In that case, please contact BloomReach to discuss how to proceed.
