ASA 5580 Upgrade 8.2(4)-->8.4.3--Zero Downtime

Hello Everyone

Currently we have two ASA 5580 in failover (Active/Standby) mode and the current version is 8.2(4),we need support ragrding some concerns

1-We have problem that when we do dynamic NAT for internal zone to outside zone we have to perform NAT examption from internal zone to all others zones(except outside) to keep no NAT,is the upgrade from 8.2.4 to 8.4.3 will solve this issue.

2-Could we upgarde to 8.4.3 with zero downtime and should we upgrade dirctly from 8.2.4 to 8.4.3 or we should go through 8.2.5---8.3.1---8.4.1

3-Regarding the current NAT statment we have in 8.2.4,do we need to reconfigure them again ,or it will work fine after upgrade.

Thanks

Hi Michael,

You can directly upgrade from 8.2(4) to 8.4.3.

Because your ASA with failover, that possible zero downtime when you upgrade.

Hello

Thanks for your reply,

I need to know if upgrade will solve the NAT issue and if I upgrade,NAT configuration will be auto-corrected or not.

Hi Michael,

The NAT changes should be done by the software but it is always good to have copy of previous version config to compare incase of any issues.

Now the benifits... Incase you are planning to upgrade to 8.4 because Cisco released new version- then I would say 'no' for it. Refer to the release notes http://www.cisco.com/en/US/docs/security/asa/asa84/release/notes/asarn84.html and if you need to use any of the new features listed, then you should go with upgrade. Note that 8.3 and above requires more memory.

Hi Michael, Mike

yes be with you. have you are real reason to go to 8.4. 8.2.5 will be the next in the train ..

8.2 has no eol statement and so should at least be supported until 2013...

If you need memory keep in mind, your Hardware is supported until July 31, 2017 (EOS is from February 10, 2011).

http://www.cisco.com/en/US/products/ps6120/prod_eol_notices_list.html , maybe than its better to plan a complete Exchange ...
