upgrading ios

[Barath.Maddireddy1]

Hi All,

we need to upgrade our IOS in Cisco ASA 5585-x from 8.4(7)3 to 8 .4(7)28  what is the best way to do it ? what are issues we can get while doing it? and these 5585-x are in the context mode like we have 15 context.

Hi Barath,

You could directly upgrade from 8.4.7-3 to 8.4.7-28. Take the backup of your current configuration before upgrade to this new version.

You could directly change ASA boot variable in System configuration and upgrade.

Procedure remains the same as you do it in Single mode. Use the link below :

Hi Barath,

.3 to .28 is an interim upgrade. So it could be directly upgrade. there is no changes in these upgrade. Interim upgrade is having mainly bug fixes.

Mark the answer as correct if it answers your queries.
