We currently have a Cisco ASA 5510 with version 5.2 of ASDM and version 7.2 of the ASA. It is my understanding that to use the Cisco AnyConnect client we would need version 6.0 of the ASDM and version 8.0 of the ASA. If this just a software update? Would there be any downtime for this update or any adverse effects that might be caused to going to the higher version? Also is the AnyConnect a separate package that needs to be purchased or is it just something that is available if we upgrade to the latest versions? How long would an upgrade like that take and what configuration changes would be necessary to allow clients to connect?
Thanks and I appreaciate the help anyone is willing to give.
Do you know of any negative imapct this might have? For example if we have sales guys using the Cisco VPN client now and we do the upgrade for ASDM and ASA could their current VPN client stop working? Basically are there any problems you've experienced due to the upgrade?

Hi Jay, not realy - RA VPN should still function after - upgrade is very stright forward and will convert config to that code , as a rule and practice however for any upgrades on devices is to backup your configuration - it is also good idea to look at the code you will be upgrading to for opened CAVEATS -you can look at opened caveats in the release notes link I posted which provides details on opened bugs to sort of give you ideas of issues.. I have been runing latest code 8.2.1 since its release back in May for example with no issues but my environment differs from others.. but you should be good..
