Migrating Forms from Classic site to Modern UI sites

Thanks for the reply Nikita.
The form currently are designed for classic UI using the old forms designer.
The main question i have for you is

  1. How do we migrate forms built in classic to Modern UI . You mentioned we can import them but the issue here is we don't have the modern UI installed yet.
  2. Can we install the new modern UI form and the classic UI side by side inside the same tenancy and use them both during our migration processes?

I would appreciate your response on this issue.

Thanks
