If you are planning to keep the 2 TB drives in the array for now, then just leave them alone. Reinserting them in a different slot is a bad idea. There is no reason to move them out of slots 5 and 6.
You are aware of the 8 TiB expansion limit? That is - if your initial installation was 3 TiB you can't expand the volume beyond 11 TiB?
You will reach this expansion ceiling at some point with your current plan, as you are going from a 6 TB volume to a 15 TB volume. I suspect you started with a smaller volume - if so, you will reach the ceiling sooner.
The recommended workaround from Netgear is to do a factory reset (which wipes all your data, and forces you to reinstall add-ons and rebuild the configuration). If you want to use that method, then you would install the first two 3 TB drives and then do a factory reset. Then you'd have a 9 TB starting point - allowing you to reach 15 TB without hitting the ceiling again.
There is also an off-line expansion procedure which can avoid the limitation. But it requires some knowledge/comfort with linux command lines, and carries some risk. And once you hit the limit, you'd need to continue using the off-line expansion method for each additional disk you upgrade.
