Upgrading the drives

Hi there.
I want to upgrade my 2 6 tb drives in the my cloud ex2. I have 2 new 8tb drives. Both the 6 tbs are full of data. can I just use a docking station and clone the drives and replace them? Can I insert the new drives format them and then just copy the data over? they are in spanning mode so not really sure what will happen?
Any advice will be appreciated.
