Cannot Deploy to IDS Appliances after FMC upgrade to 6.6.1

[loving_networks]

Hi All,

Hope I have placed this in the right location.

I have upgraded our FMCv from 6.2.3.16 to 6.6.1, however, since the upgrade I can no longer deploy to the appliances as the deploy button is greyed out.

I can confirm appliances run 6.2.3.15 code so are compatible.

Error is:

[Default Prefilter Policy_1] Prefilter policy is not supported on this device. Prefilter policies are supported only on Firepower Threat Defense devices running at least version 6.1. Without a prefilter policy, access control uses inner headers to handle sessions in non-encrypted encapsulated traffic. You can safely ignore this message.

*note: This message was present before upgrade but allowed us to deploy.

Suggestions please.

Thank you.

To work around the problem, you can change the applied Prefilter Policy to be the system provided Default Prefilter Policy, which will allow deploy to occur.

Hope this helps.
