[CentOS] Migrating to nvme and expand

I have older SATA disks (2 of them size 2T) in a software raid config
running CentOS 7.

/dev/md127 is / and xfs
/dev/sda2 is swap
/dev/md126 is /home and xfs

I desire to get a new (single) NVME 4T disk.

What is the correct way to copy the software raid to a single "new" NVME
disk ?
then expand the /home file system to All the remaining space?
