Also, there are NAT changes. Check the below link to get some idea. Search in the forum , you will lot of postings with ref to similar upgrade. If you have a spare unit, I suggest you test the configuration (new) on that before move to production.&nbsp; </P><P></P><P><A href="https://community.cisco.com/document/48646/asa-83-upgrade-what-you-need-know">https://supportforums.cisco.com/docs/DOC-12690</A></P><P></P><P>hth</P><P>MS</P></BODY></HTML> Tue, 11 Feb 2014 22:01:53 GMT https://community.cisco.com/t5/network-security/upgrading-asa-5505/m-p/2429025#M269829 mvsheik123 2014-02-11T22:01:53Z
