Ok So I followed instructions @ https://docs.particle.io/guide/tools-and-features/libraries/#using-the-desktop-ide
I did not get a notification telling me that I need to migrate my library.
I did however get a banner alert telling me Library Ucglib@1.3.3 was successfully uploaded!It’s only visible to you.
And it is displayed in the Desktop IDE as Ucglib 1.3.3
The library.properties file did not contain field url so i added url=https://github.com/olikraus/ucglib
I did not add the git remote to the repository field as unsure where that is.
When I try to compile an example from the library I get error clib/ucg.h: No such file or directory /src/Ucglib.h:61:22
Also I can not see it in the WEB IDE
