PIX 515E Upgrade PIX-OS

[dtuttle]

Hello forum, I need to upgrade a PIX 515e from 6.2.(2) to 6.3.(4) to enable the proper configuration within our Tacacs+ secure ACS server. I currently have Site to Site VPNs and a client to site vpn group setup. My question is: Will I need to generate a new RSA encryption key after the upgrade? If so will the VPNs need to be reconfigured after the new key is generated?

Not 100% sure, but I think you only need to regen your key if you change hostname and/or domain name.

Hopefully someone will correct me if I am wrong.

Thanks,

Josh

I have never had to regnerate the key, and mine has lived through a couple of OS upgrades. Right now I'm on 6.3(3).
