Hi All,
Issue: Looking at upgrading 3 x 9800-40 SSO controllers from 17.3.3 to 17.3.4c via DNAC Version 2.2.2.5.
Uploaded C9800-40-universalk9_wlc.17.03.04c.SPA.bin into DNAC gold image repository. All good apart from the upgrade readiness report fails on ISSU Compatibility Check?
DNAC expects a compatibility matrix to be uploaded, the only matrix available starts at ver 17.4 train??..
Does this mean the upgrade will fail or just wont be an ISSU upgrade? Very confusing, do I upgrade to a version that has a matrix available for ISSU?
Can anyone share the guide to upgrade through DNAC
