3. Read the Release Notes
Cisco frequently includes "Caveats" – known bugs in the release. Search for "CSC" IDs in the 9.3.8 Release Notes to see if any affect your specific deployment (e.g., specific SFP modules or routing protocols).
vs. NX-OS 10.2(x):
- 10.x introduces breaking CLI changes (e.g.,
featurevsinstallcommands). - 9.3.8 is more predictable for legacy automation scripts (Ansible, Puppet).

- Review Cisco release notes and platform compatibility for NX-OS 9.3.8.
- Download image from Cisco's official portal and verify checksum/signature.
- Backup current configuration and existing image(s).
- Stage image to switch flash and verify integrity.
- Test upgrade in lab or non-production device if possible.
- Schedule maintenance window and notify stakeholders.
- Follow Cisco's documented upgrade steps (copy image, set boot variables, reload) and monitor logs.
- Verify functionality and run post-upgrade validation tests.
- Retain previous image for rollback until stability confirmed.

Alternative: Can I Use nxos.9.3.8.bin in an Emulator?
Yes, for lab purposes:
- EVE-NG Community Edition – Supports Nexus 9000v images, but
nxos.9.3.8.binmust be converted to.qcow2. Requires legal access to the original.bin. - Cisco CML (formerly VIRL) – Offers official Nexus images, but again you need a license.
Note: Emulating Nexus switches is CPU-intensive. Allocate at least 8GB RAM and 4 vCPUs per instance.
