Upgrading to larger hard drives on MyCloud Ex2 Ultra

i originally installed two 4TB drives in RAID on my NAS. They are now about 75% full and I am considering purchasing two new 18TB drives to replace them.
Is there an easy way to go about adding the new ones and moving all the data over? Or do I need to move the data somewhere else somehow before installing the new drives and rebuild the shares and all that over again?

Thanks
