PIX ver 6.3(4) IOS

[hornbeck]

Hello,

I have two PIX515e appliances that were configure in failover mode with IOS 6.3(4).

I upgraded one of the boxes to 7.1. We now want to remove this 7.1 and put 6.3(4) back on the device.

Please help me with steps involved in doing this.

Also, I looked on the Cisco site and could not find this exact version of IOS to download.

Any advise or thoughts are greatly welcome.

HI .. you might need to use the downgrade command .. please refer to the below link for some help .. Note the article referes to version 7.0 but it should be the same procedure

Excellent...the upgrade was a pain in the ass! Took hours...the downgrade actually worked as advertised...thanks very much, and will rate this as a 5.
