Has anyone upgraded the ASA Failover pair From 7.2 to 8.2 ?
Does it incurs any downtime during the operation or its transparent for all the connections passing through.
I have read many documents which says that you can go from 7.2 to 8.2 directly, and i was able to upgrade stanalone firewalls without any issues.
But for failover, will failover work if one ASA in on 7.2 and other one on 8.2, or an intermediate upgrade is required.
Request help in this topic.
This is possible in 7.2 to 8.2 and i have done upgradation in one of the main Telecom Company in India and I am 100% sure about that.
The two units in a failover configuration should have the same major (first number) and minor (second number) software version. However, you do not need to maintain version parity on the units during the upgrade process; you can have different versions on the software running on each unit and still maintain failover support. To ensure long-term compatibility and stability, we recommend upgrading both units to the same version as soon as possible.
I wish you to have a gr8 success ..
