Upgrade from ASA 5520 to ASA 5508-X

[mviker2575]

Hello,

We just got a new ASA 5508-X firewall and I am in the process of bringing it to life. the firewall it's replacing is an ASA 5520. 

The interfaces and naming conventions are different, so that makes it difficult to apply a backup copy to the new 5508-X. Is there any method available to convert either a saved config OR backup ASA 5520 file so that it can be easily applied to the newer ASA 5508-X? 

Only other option is to manually configure everything. Not looking forward to that.

Thank you!

If you were on a quite recent release on the 5520, then you can take the config and just replace the interface identifiers and apply the config to the 5508. That worked on a couple of migrations to new ASAs.
