Performance, scalability, and availability of on-premises connectivity for hybrid integration scenarios have now been enhanced by having dedicated Software AG Universal Messaging (UM) nodes for each tenant. A tenant can be associated with dedicated UMs based on the license. Contact Software AG Global Support for assistance in setting up the dedicated hybrid infrastructure.

If you are using hybrid connectivity and when you update the on-premises settings for the first time after the upgrade, restart the on-premises webMethods Integration Server to resume hybrid connectivity. If you have whitelisted the Cloud UM hostname or IP in the firewall, then you have to also whitelist the new UM hostname and IP along with the old ones. See the following table for information on the IP addresses.
