Hi
As soon as you remove the old outside interface, all nat and acls and other related config go away.
What you can do:
- export the config using cli
- remove old outside interface
- reconfigure the new port using the exact same name (outside)
- from the exported config, copy/paste all acls and nat (and other related config like routing for example...) into asa using command line.
You should be ok after that.
Thanks
Francesco
