Hi,
Can anyone let me how to migrate EUM from on-prem to saas?
Hey there. This is pretty easy actually. You just change the configuration in the controller to use the SaaS CDN for EUM instead of your own server.

And you will loose all of your data stored in the Event Service. Unless AppD has a migration tool for it.
