When upgrading from one version of FME to the next, I can upgrade some upgradeable transformers, and I can also upgrade the readers and writers to the latest version. But what about the readers that are called by the FeatureReader (and writers by FeatureWriter)?

We just upgraded from 2024.1 to 2025.1, and I upgraded the FeatureReader transformer reading a geodatabase. Does upgrading the transformer, upgrade the GDB reader functionality? Or does it automatically call the latest GDB reader? Or does it stick with the old?
