I would request you to upgrade first to ASA 8.4.6 and then upgrade to the ASA 9.1.

Hi,

There are some changes between the ASA 9.x and 8.4.x.

They should be minor and seamless.

Hi Vibhor, One last thing.

Hi Vibhor,

 

One last thing. Does 9.1 supports al the features of 8.4?

Specifically I want old vpn client that runs on IPSec.

It should not happen that some of the configuration becomes useless or something stops working.

 

Cisco Employee

Hi,

Hello Vibhor,

 

Can you suggest a stable release of 9.1

which version should i upgrade to?

Since you are already on the

Since you are already on the new NAT style, it should be smooth.

Note that as of 9.0 IPv6 and IPv4 access lists are unified, so the "any" keyword is now dual-protocol.  Use "any4" or "any6" if you want just one protocol.  The upgrade should preserve the intent of your current rules, but you may want to review the results with more care than usual.

IPsec tunnels can use IKEv2, but this is not required.
