want to use Blockchain dl'd from windows HDD and use it on a raspberry pi. can I do this without redownloading?

Hello,

I recently downloaded the btc Blockchain to a 2tb HDD from a windows machine. I want to use it for a pi I have coming but want to know if I will be able to use it when it gets here. Will I have to redownload it?? Or can I use it? Is there a way to convert the file type of I have to? I know debian used ext4 and did not think about that until I had like 30% of the chain downloaded...which is where I am with the progress as of writing this. Any help would be much appreciated as I would rather not have to start over if possible. It's. Taking. Forever.

Again Any help would be awesome. Thank you.
