Hello,
Yes, you can download the ASA activation key. If you would like the failover to work, temporarily you would need to downgrade the webvpn license from 5000 user license back to the default of 2 user license.
To downgrade, you would need to send an email to licensing@cisco.com requesting the same. I would suggest that you send them the output of show version from the ASA that you would like to downgrade the 5000 users to default 2 users license and explaining that you would like to get the downgraded activation key.
FYI :
- For pre-8.3 ASA code : For failover to work, both ASA needs to have exactly the same hardware, software and license. If 1 ASA has X webvpn user license, the other ASA also needs to have X webvpn user license.
- For 8.3 & above codes : You do not need to have the same license for failover to work.
So either downgrade the license or upgrade the firewall. Please note, upgrade to 8.3 will involve change in NAT styles and other config changes.Refer to command reference, min. req. & release notes prioir to upgrade.
Hope this helps. Please reply back if you need any further assistance.
Regards,
Chirag
