Error when trying to migrate catalog from LrC (Classic) to Lightroom.

Ah interesting. It wants you to not be on battery power for the migration and your external hard disk where a bunch of your classic images are needs to be connected. The third error is probably caused by the external disk not being connected.

Also, be aware that the migration requires all your images to be first copied to your internal hard disk before the images get uploaded to the cloud. If you don't have enough space on the internal hard disk, the migration will fail. The only way around this is to break the Classic catalog into multiple smaller catalogs that you migrate one-by-one.
