In Transformer version 8.3, models saved in binary format now use the .pyj file extension. In Transformer version 7.x, models saved in binary format used the .pyi file extension.
Before upgrading Transformer version 7.x models to Transformer version 8.3, you must save your .pyi models in the .mdl (text) file format. We strongly recommend that you keep a .mdl file backup of all IBM Cognos Series 7 models that you upgrade to Transformer version 8.3.
