I'm going to be implementing a new pair of 5510s as replacements for our 515s. The 515s are running 7.1(2). The ASAs came with 7.0(6) but I'll be upgrading those to a release higher than our PIXs before I implement them.
We use failover, remote-access VPNs, VLANs, syslog, and OSPF. I'm aware of the failover difference (we currently use the serial cable on the PIXs), but I'd like to know if there are any other gotchas that someone can give me a heads up on. I'd planned on just migrating most of the config as opposed to creating a new one on the ASAs from scratch. Any feedback would be appreciated.
