I agree this would be a large change to manage, and you can continue with your current grid setup for a long time yet. Other factors might influence a move though, such as a need to manage your analytics in a cloud environment rather than a data center. As you evaluate these needs, keep in mind that your SAS 9 code can work largely unchanged in SAS Viya, and you can adapt to using CAS for the processes that would benefit most from new techniques, in-memory analytics, and more parallel processing. SAS Viya is continuously delivered with updates every month, which are easy to adopt on whatever cadence works for you.
