How can I migrating my Model-builder desktop applications from ArcMap to ArcGIS Pro?
If the tools are in a Tool Box, you can take then and connect them to ArcGIS Pro - Connect to a toolbox—ArcGIS Pro | Documentation
Is that what you are asking about because your mention model builder applications? Did you mean model builder geoprocessing tools?
Yes Modelbuilder is collection of geo-processing tool for workflow.
Ok, then I would try looking at this: Analyze Tools For Pro—Data Management toolbox | Documentation
