Bad perfomance in SaS Viya comparing Enterprise Miner

[Preguntarius]

Hello everyone, I'm now migrating a large amount of models from Enterprise Miner to SAS Viya and in quite a lot of cases I see the same phenomena, that I cannot reproduce the EM-results in SAS Viya. I always use exact the same data and I try to select the same hyperparameters of the model in SAS Viya as in EM (which is not so easy because the settings in SAS Viya and EM are not quite the same). I would expect similar results, but it's often not the case. And when I choose f.e. Gradient Boosting  with 100 Trees, learning rate 0,1 etc. in both SAS Viya and EM and get 0,8 in EM and only 0,58 in Viya, I'm really confused.

Did anyone have the same experience and perhaps have found some sort of solution?

Best regards and thanks
