Roll back configure replace firewall configuration

configure replace

I have been working on ASA's for a will and when I need to revert back to the startup configuration I always need to reboot the ASA since copy run start just over writes the run. I seen that there is a configure replace command but with my 5525x running 9.2.1 I do not have the option:

ASA-HA-WEB(config)# configure ?

configure mode commands/options:
  WORD             Configure from HTTP:
                   http(s)://[<user>:<password>@]<location>[:<port>]/<pathname>.
                   Place IPv6 address within square brackets if a port is
                   specified.
  factory-default  Configure from factory-default
  memory           Configure from memory
  net              Configure from tftp

exec mode commands/options:
  terminal  Configure using terminal/console

Is there something I need to do to enable this?

Copy off a configuration you want to revert to to the local disk0: - i.e.:

copy run disk0:/good-config.txt

Then you can use it to copy over the running-config at any time:

copy disk0:/good-config.txt run

You can similarlyuse a network-based location and tftp but that depends on reachability to the store location.

I just tried this and it looks like it was just over writing the running-config. It is not replacing it. Is there another way to restore?
