Celerra Migration options using Celerra Replicator V2

We are having four Celerras A,B, C and D. Presently we have  a Replication running on Production site A and its DR is B. Now we need to Migrate the File systems to the other two Celerras with C being the New Production and D its DR site. C and D are brand new Celerras. So, i would like to ask  what is the best way to migrate the file systems to the new Celerras C and its DR celerra D with minumun impact on the Production. We presented 3 options

Option 1

1) Establish a replication from B to C

2) Cutover production to C and reverse replication to B.

3) Establish Replication from C to D

4) Cutover DR to D.

Option 2

1) Establish a Replication from A to C and also from C to D ( two hops)

2) On cutover Switch production to C and DR to D.

Option 3

1) Establish Replication from B to C and aslo from C to D ( three Hops)

2) Cutover Prod to C and DR to D.

We are using Celerra Replicator V2 . DART Code is 5.44.408 on all celerras. I think option 3 is not possible as V2 supports only 2 hops. I would like to hear from which option is best with minumum impact on Production and are there any other options we can go for.
