Cisco Cisco Catalyst 6500 Series 7600 Series ASA Services Module Notas de publicación

See the following table for the upgrade path for your version. Some versions require an interim upgrade 
before you can upgrade to the latest version. Important fixes were added to Version 9.0(3) that make it 
possible to upgrade easily to later versions, so we recommend upgrading to 9.0(3) or later.

There are no special requirements for Zero Downtime Upgrades for failover and ASA clustering with 
the following exceptions:

Upgrading ASA clustering from 9.0(1) to 9.0(2) or later: due to CSCue72961, a Zero Downtime 
Upgrade is not supported.

Upgrading issues with 8.4(6) and 9.0(2) for failover: due to CSCug88962, you cannot perform a 
Zero Downtime Upgrade to 8.4(6) or 9.0(2). You should instead upgrade to 8.4(5) or to 9.0(3) or 
later.

For detailed steps about upgrading and configuration migration, see the
