This video will show you the correct upgrade path for an upgrade of the NX-OS to version 5.0(2)N1(1)
When updating from 5.0.3.N1.1b to 5.5.1.N1.1 on a pair of 5548up's in vpc running Layer 3 and the 2248 extenders connected via vpc to both 5ks will the 2248's be disrupted if I upgrade the 5548's one at a time? We are runing HSRP on the vlans so they should fail over to one another and i know if running layer 3 it does not support ISSU but the 2248's are layer two so will they support the ISSU?
