•Do not change any configuration settings or network settings during the upgrade. Any changes in the network settings may cause a disruptive upgrade.

•Cisco NX-OS Release 5.0(3)N2(2b), Release 5.0(3)N2(2a), Release 5.0(3)N2(2), and Release 5.0(3)N2(1) are ISSU-compatible with NX-OS Release 4.2(1)N1(1) and later releases.

•Downgrading from NX-OS Release 5.0(2) to NX-OS Release 4.2(1) is disruptive.

•Upgrading from NX-OS Release 4.2(1) to NX-OS Release 5.0(2) is a nondisruptive upgrade (ISSU).

•Upgrading from a Cisco NX-OS Release 4.2(1)-based release to Cisco NX-OS Release 5.0(3)N2(2a), Release 5.0(3)N2(2), or Release 5.0(3)N2(1)is nondisruptive.

•Downgrading from Cisco NX-OS Release 5.0(3)N2(2a), Release 5.0(3)N2(2), or Release 5.0(3)N2(1) to a previous release is disruptive.

•When a Layer 3 license is installed, the Cisco Nexus 5500 Platform does not support an ISSU. Hot swapping a Layer 3 module is not supported.
