A router cannot tell the difference between upgrade and out-of-the-box in general.
Turn on an unconfigured router and then paste in an existing configuration.
That is an upgrade that looks like out-of-the-box.

Thanks,

1) CE - either existing CE stuff can handle this during upgrades (qv discussion about upgrade vs out-of-the-box), and/or suitable warnings.
Use of "permit all" policy achieves the desired effect on CE, and satisfies the requirements of this standard.
