Failed Deploy from FMC causing Outage

[mumbles202]

Created a new vpn policy the other day and pushed it to a pair of appliances, but when i did the deploy failed and as a result faced an outage briefly on the network.  Modified the configuration, redeployed but same results (failed plus an outage).  Looking online, found this:

Which seems to suggest that this is a bug.  Anyone else experienced this and have some possible work-arounds, other than maintenance windows for what should be benign changes?

Hi,

The defect that you have mentioned is applicable only when we make changes pertaining to device parameters/flex config or VPN.

For instance, if the change is in an access control policy or intrusion policy and then the policy deploy fails the defect is not applicable. No temporary drop in connection would be seen.

Thanks for the information.  The change I made was indeed adding what seemed like a simple vpn configuration.  NAT and Access Policy were already previously deployed, was just the vpn that failed and caused the outage.

How did you solve the problem, did you return the changes made?
