Upgrade FWSM Failover Pair

Hi All

An old thread confirmed that it is not possible to upgrade an FWSM failover pair to a new minor/major version without downtime. see https://supportforums.cisco.com/message/3019703#3019703

What abaut newer versions? I like to upgrade from 4.0(6) to 4.1(2).

With theese versions, is it possible to upgrade without donwtime?

Has anybody already tried it?

Thanks

Patrik

Re: Upgrade FWSM Failover Pair

Hi Patrik,

Upgrading between major or minor versions without downtime is still not supported, unfortunately. Here is the documentation for that:
