In reply to Tamara Barker. Hi Tamara, Jumping in to answer for Venessa (she's away). I cannot answer about the specific customer scenario, but in my experience the biggest challenges for transition are:

Data/files tied to desktop that are more difficult to access in a browser-based environment

Very sophisticated (read: complicated) flows that chain lots of tasks together. SAS Studio can read EGP files but not all tasks translate over.

Other changes related to SAS environment that aren't really a result of the change from EG to Studio, but are more due to centralized data and code processing. These require change management too.
