I built a model builder in ArcMap 10.8. It saves all the intermediate data automatically to the default geodatabase. It also has the relative path checked.
Now, I am transferring the model builder to ArcGIS Pro 3.1 but it still shows the previous default geodatabase. If I add a new tool it syncs with the current ArcGIS Pro workspace but the older part of the model stays the same as the previous default geodatabase. What should I do?
Take a look at Find and Replace for Model Builder
You can also set the replace value to just %scratchGDB% which will direct it to the location of the scratch workspace in Environment settings making the Model a bit more portable.
As always, work on a copy to be safe.
