I haven't been able to even get that far. I have attempted migrating a simple project from Standard to Pro. I have yet to get it to succeed. All I get is a blank page. I must be doing something wrong. From my existing Standard project, I download the project as a ZIP. I then choose the Import Standard tile in Pro. It tells me the import was a sucess, yet all I get is a blank page.

I have also tried creating a project from scratch, but the component selection is so limited I don't see how I can realistically create a project in Pro.

@rehsd For what I understand, you (the user) has to create a 'device' for use on the schematic and pcb.
This device consists of a symbol (schematic part), a footprint (for the pcb) and a 3D model.
If you have the device you can start creating your project.
And if enough users create devices and make them publicly available, we'll have a nice library to choose from. But this'll take time (and users willing to share their devices...)

@mijnmodelbaan,

And the User Contributed Devices have to be checked carefully. Ideally this should happen before they are accepted into the library rather than every user having to check every device before they use it each time they use it (because a contributor may have changed it).

It also causes a ton of issues with the schematic. I have a perfectly working and complete board in EasyEDA STD. I export it and import into EasyEDA PRO, and that works fine.
But looking at the schematic DRC there are a ton of issues that says "Component attributes does not match the Supplier Part, It is recommended to use Device Standardization"

Quite horrible, and it makes migrating non-feasible.

Hello, this error is caused by the fact that our system libraries may have been updated for some devices after you created this schematic. This is not a big problem, even a negligible error, you can take a look at this tutorial: ‍‌‍‌‍⁠‬‬⁠‍‌‬‬⁠‌‬⁠⁠‌‍‬⁠‍‍How do I resolve the "Component properties does not match the supplier part" error? - 飞书云文档 (feishu.cn)
