Hi @SasStatistics,
Good news! All of your learning in the SAS programming language will translate over to SAS Viya. Any code/procedures/techniques that you learn in a SAS 9.4 environment (using SAS Studio or anything else) will work exactly the same way in a SAS Viya environment.
In addition, SAS Viya has capabilities in CAS, the in-memory analytics server. You may find that some challenges/data are better suited to these methods, and you can apply those SAS Viya techniques as it makes sense for you -- but that is optional and can be done over time.
