Nilesh,

I can't comment about whether it will cause serious problems beyond the
warning, because I don't know. However, it looks scary and I wouldn't be
surprised if you have issues or corruption.

As far as migrating to mod_wsgi, I'd suggest doing a deployment of Review
Board on a new server and then comparing the configurations. There's no
document that we've written but there's probably plenty out on the internet
about switching to wsgi.
