NAS ware 2.0 with NAS ware 3.0 in 4bay Synology

I have two WD Red 3TB, WD30EFRX with NAS ware 2.0 marked on them.
I would like to put them and two more new 3Tb Red drives in a 4Bay Synology NAS. The new WD Red 3TB, WD30EFRX are now NAS ware 3.0.
My question is will they work together? Will the older drives restrict the new in any way or vice versa?
