Upgrading ESA devices to 11.1

[mmonocchi]

I don't post here that often so I apologize if I am in the wrong location. I just had a question about a firmware upgrade to our ESA C370 devices. I realize these are old devices and support for them is waning. We are current at 10.x and as I understand, 11.1 will probably be the last regression tested release for this device. Every upgrade to date has gone well. Just wondering if there are any major gotcha's with this release I need to look out for. I know about the DLP engine and have discussed that with Cisco. Thanks for any input.

From the release notes for Async OS 11.1

The following hardware is NOT supported for this release: • C160, C360, C660, and X1060 • C170, C370, C370D, C670 and X1070 appliances

So Async OS 11.0 would be the last upgrade available for x70 hardware models. There should be no hardware model specific issues running 11.0 on C370.

You can always review the release notes for all Async OS versions here which has links to known and fixed defects on the bug search tool:
