Will my hybrid applications be automatically upgraded with Talend Cloud?

No. Setting up hybrid for these applications requires you to install and update them, as well as their direct dependencies, manually, according to the on-premises product release planning and lifecycle. Automatic Talend Cloud updates are not available for the hybrid applications. Direct dependencies include Kafka, MongoDB, Tomcat, and Talend Dictionary Service if you have the license for it.

Refer to the Product Terms page to learn about the supported versions for hybrid.
