I agree, ArcGIS Pro needs an ASPX Doctor!. So, in ArcGIS Pro they do use relative path names to the data. However, your issue is ALL the files have moved (but hopefully the file paths are the same). In that case, please recall the following, once a layer or layerx file is opened in an ArcGIS Project the information is stored within the project (i.e., it does not reference the .lyr or .lyrx file directly once loaded).  This means if the layer referenced a database, the database connection information is stored in the project.aprx, not the path to the layer file itself.  If one has the project open you can use the Catalog View. You can update the paths in one item, such as a single map in the project, or access all the paths in the project. You can find and replace specific strings in the paths. To update paths in the current project, see Update data sources—ArcGIS Pro | Documentation. Second Option, update the Project path itself "within" the aprx, thus allowing the relative paths to work. To do this, recall that the .aprx file is actually a ZIP file. So, rename the project.asp to project.zip then copy the DocumentInfo.xml file out of it, edit in NotePad++, then copy-replace back into the original .aprx. Save the file and copy into the .zip; Rename the .zip back to .aprx. The next time you open the project it will use the NEW project path as the start of the relative pathing to your other files. ...
