I don't quite understand your question. You have a 4 node cluster, with one pair of FAS8060s and one of FAS8080s? These platforms are both still supported by current versions of ONTAP, and we will provide support contracts through end of 2022 on them.
What challenges are you facing? What does your budget look like? What is your driver for change?
Current platforms are FAS2600(AFFA200), FAS8200(AFFA300) and FAS9000(AFFA700), and are available with spinning disk, SSD or hybrid configurations. We also have an all flash compact high performance unit, the A700s.

Ok, I understand.
System sizing aspects include capacity, performance, parallelism, as well as constraints such as budget, space, power and cooling, and enhancements such as support levels and software licensing. This topic is probably too complex and commercially sensitive to cover on our forums.
At a broad stroke, a single HA pair of FAS9000 systems will likely meet your requirements, but without detailed analysis of your environment, we couldn't say that is the correct choice for you.
Your leasing reseller should be able to work with you to identify your sizing requirements for a replacement system.

Yes, with Clustered ONTAP you can add a new set of nodes and drives to the cluster and move the data across using "vol move" functionality, just as if you were moving it between the existing four nodes. You will need appropriate cables/SFP+/optical fibre to connect all 6 nodes simultaneously to the cluster switches for migration. Post migration, you would unjoin the departing nodes, and then convert the cluster to switchless clustering.
Or if you own the disks but not the controllers, we have a "non-disruptive headswap" procedure using aggregate relocation available for our services partners. This is a safe, but complex, activity that we only support for trained technicians.
Hope this helps!
As I said earlier - I can't say for sure that a single HA pair FAS9000 is the correct choice - a 4-node FAS8200 cluster might be correct, and then in that case, our ARL headswap procedure would work.
If the disk is also being returned, and replaced like for like (capacity), you could use "storage disk replace" to copy then fail-out the old disks one at a time
