We have two fabrics with one 4100 at FOS 5.2.0a, one 300 at FOS 6.1.0c, one 5100 at FOS 6.3.1a and one 6510 at FOS 7.0.0 in each fabric. Now we have to join two new switches (6520 at FOS 7.2.0d) to these fabrics. We know the target path for the 300, 5100 and 6510, but I'm not sure about the 4100. My understanding is (please correct me if I am wrong) that I have to upgrade the 4100 from 5.2.0a -> 6.2.2e -> 6.3.2d -> 6.4.3d -> 7.0.2c -> 7.1.1c (I think the last supported for 4100).

4100 switches are supported until 6.4.3h.
From 5.2.0a, you have to jump to 5.3.2c, 6.0.0c, 6.1.2c, 6.2.2f, 6.3.2d, 6.4.3h
