UE4 how to move materials between projects?

I tried dragging a material from project to project - did not work
Tried exporting - it exported it as .COPY , which the other project did not recognize
Tried to “Migrate” - did not have the other project open.

How do I move assets/materials between project?

Right click on the asset you want to move > Migrate > Show the other project’s Content folder > Done.

I misread the “Migrate” dialog title, it said that the following assets will be moved. I thought it asked me where I want this to be migrated. I had to click OK and navigate to the other project’s content folder.
