Best way to Install IPS modules in ASA's in Failover
We have a customer with a pair of ASA 5585-x in failover mode. They are looking to install a pair of IPS modules in these ASA's.
Is there a way to install the IPS modules without any downtime. I know for failover the ASA's have to have the same hardware, so if I install the IPS module in the standby unit it will break the failover between the ASA's.
What is the best way of doing this with as little downtime as possible.
I know I could bring down the standby ASA install the module, and then when it's booting up power down the primary ASA and then install the module into this ASA. Is this the best way or is there a way to achieve this with zero downtime?
