Plesk 12.5 upgrade with MS FrontPage extensions

So I'm working through testing of migrating my plesk 12.0 install to 12.5.30.
In the check it mentions I'm missing the "frontpage" apache module.
I have more than a dozen FrontPage sites that need to be migrated.

What do I do to make the migration work (at least for the frontpage portion of the problem...)
