WLC9800 L - SMU missing

[craiglebutt]

i

Looking to test the in-service upgrade, but it seem the SMU is missing from the Software Management.

Running 17.9.4a in a HA. (don't know if this options is avlaiable in HA)

We do have DNA Center, but not had it long, if this can be used?

Cheers in advance

yes recently used 2.3.X DNAC with WLC in HA - upgeaded using ISSU

you need to upload the image to DNAC and set as Golden Image, download DNAC ISSU matrix XML from Download site

when you upgrading controller select ISSU Option and upload XML to check and DNAC Do the Upgrade.

Hope if AP connected to that you can have rolling upgrade (if this is testing and you can connect AP and test the AP upgrade process also to confirm ISSU works as expected)

The first thing that catches my attention in that screenshot is Current Mode - Bundle.
ISSU and SMUs are only supported in Install mode so you'll have to switch to install mode first if you intend to use ISSU or install SMUs.
