I have migrated SPRO configurations from DEV to QA environment for my custom Task Model , Business Transaction Type , Variant Id Etc. through customizing transport. All the config are migrated successfully but the custom task model is not appearing for QA communication system in AFC frontend on selecting created Task from Task Model Option. Please advise should the QA system be opened and configurations in SPRO needs to be done there to make it visible in AFC front end. Just wondering if this config activity should be taken as a Cut-Over activity during Go-Live.
