I would like to upgrade two PIX 535 in failover LAN Active/Standby configuration from 6.3(5) with PDM to 7.0(1) with ASDM.
I found some datasheets on Cisco for that.
I also searching for the procedure to downgrade from 7.0 to 6.3 in case of important issues.
I saw that I could use the downgrade command to restore the old PIX image in 6.3 and the configuration but I did'nt see anything about the method to go back to PDM 3.0.
Could somebody help me on that issue ?
