Firmware Compatibility Affecting Catalyst 3850x & ASA 5545

[Sir-MAK]

Greetings,

I recently updated my stack of Cisco 3850's IOS to  Version 16.9.3a. I am running ASA ver: 9.8(2)26 on my ASA 5545.

The stack connects to the ASA and then the ASA connects to the edge device. Are there any compatibility issues between an up to date IOS and an old ASA version?

Thanks in advance!

I do not see any issue or incompatible issue until we know the full problem and description to find is there any bugs around.

can you please explain the nature of the problem after you upgrade?
