Migration Assistant not working
I am trying to transfer my files from an old macbook pro to a new macbook air. I have followed the steps given and updates both to macOS Catalina version 10.15.3 and mac OS High Sierra version 10.13.6 respectively. Both laptops are connected via the same wifi. When I start MigrationAssistant, the icon of my old macbook appears but then I click on it, it says on my new macbook air that the OS on my old macbook is not up to date. How do i resolve this and transfer my files to the new macbook preferably without the use of a hard drive and just migration assistant?
MacBook Pro 13", macOS 10.15
