LR classic v LR

I have used LR classic until now, but I have a problem when I am using a laptop as I do not have the necessary amount of storage needed... Can I use LR instead when on the road?

Always better when you describe the problem you are facing, rather than not mentioning the problem you are having in your original post. If you are nearly out of space, one solution is to put the photos on an external drive. If you don't want to carry an external drive with you when you travel, then you could use Lr (not Classic) and then you need to understand how Lr and LrC interact with each other (which has been described in many places) and that you my have the 20GB plan, so don't fill up that 20GB.
