Best way to manage Lightroom Classic library with two PCs

Hello, 

I recently built a editing rig and I am lost when trying to figure out the best way to go about this.

currently I have my entire and rather large Lightroom Classic catalog on my old laptop and it syncs via Creative Cloud to Lightroom on my iPhone as well.

What is the best way to move my entire library (photos, presets, edits etc) from my laptop to my editing rig without getting tons of errors. also is there a way to still be able to use my laptop when on travel to be able to edit on the go and than transfer my work to my editing rig when I get back to the office (External drive maybe) from what i understand i can only sync via creative cloud to two devices.

Thanks in advance
