Hello,
For Layout snapshot you can use this guide : https://forums.stardock.com/486084/fences-support-faq#backupsnapshots. Just as a reminder, for this to work, your actual files and shortcut, won't be copy over to the new system. That part, you'll need to make sure it was installed or copied over to the same location as your old PC manually.

For License, that you need to do manually, just need too deactivate the old PC activation and reactivate on the new one. Use this guide to deactivate old activation : https://forums.stardock.com/486311/accounts-and-activation-support-faq#deactivateproduct

Thanks
