N66 to 1900P - reuse config?

[hifiwifi]

Upgrading to a 1900P. Is it advised to use the same saved config, or is this even possible? Risks? Thanks.

No, you must not load a config file from another router.

It is recommended that you set things up from scratch but if you don't want to you can use John's NVRAM utility in "migration" mode.
