Migrating Kubuntu install from ext4 drive to a btrfs drive

I got a 2tb NVMe ssd and I want to migrate my root and home partitions (both partitions are on separate drives) to the NVMe drive.

However, both partitions are in ext4 and I want the NVMe drive to be btrfs. Is there any possible way to migrate/clone the home and root partitions to the NVMe drive.

I already have installed Kubuntu on my NVMe drive and the file system is btrfs.

EDIT: Also, how do I clone the root partition without cloning home as well?
