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.

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) or 9.1(1): due to CSCue72961, hitless upgrading is not 
supported.

Upgrade issues with 8.4(6), 9.0(2), and 9.1(2) for failover—Due to CSCug88962, you cannot 
perform a Zero Downtime Upgrade to 8.4(6), 9.0(2), or 9.1(3). You should instead upgrade to 8.4(5) 
or 9.0(3) or later. To upgrade 9.1(1), you cannot upgrade directly to the 9.1(3) release due to 
CSCuh25271, so there is no workaround for a Zero Downtime Upgrade; you must upgrade to 9.1(2) 
before you upgrade to 9.1(3) or later.
