Many people have this question. The other plugins that claim to keep both comments systems look like they haven’t been updated in a year or more. Given how often facebook’s API stuff changes I’d test carefully before using them. It does NOT seem possible with the official Facebook plugin.
This plugin does not replace or remove the native WordPress comments but instead appends itself to the end of the content (and before the WordPress comments) so that, in effect, they work together. As far as I’m aware the official Facebook plugin does not do this.

I have had a blog for 3 years and would like to switch to the FB comments. Can I keep my WordPress comments during this change or will those be removed? How will the old comments look with the old avatars if I have the new FB comments?
Thank you for your feedback!
