Hello to all friendsI wanted to know if the Python version with which we wrote the module and did everything was different from the Python version with which we want to install the module.Thank you for your help.
Models in Arcgis Pro can be saved to prior versions so that covers the python 3.6 to 2.7 aspect
ModelBuilder: migration to ArcGIS Pro—ArcGIS Pro | Documentation
There are tools available to consolidate toolboxes
Consolidate Toolbox (Data Management)—ArcGIS Pro | Documentation
But I wouldn't worry about what happens as python moves to 3.7, 3.8 etc, because the tools that rely on arcpy will have python version checks
