No, it really isn't so bad in most cases. Yes, if you're using load balancers, 
you need IPv6 capable LB. That's about
90% of the LB market now. Log analysis, yeah, you're going to need to update 
your parsers, OR, configure your LB
to do 6->4 translation. (Of course you lose something in the translation in 
that case).

Yes, you _MAY_ need to update database records, but, most servers don't 
actually.

Depends on your environment, actually. Most IT environments it turns out to be 
a pretty major challenge, if, for no
other reason than the fact that most Firewall/IDS/IPS vendors are terribly 
lagging in their IPv6 products.

We can agree to disagree. I have found that it is far more important (and 
generally easier) to get your servers on to IPv6
so that when the first IPv6-only eyeballs start to emerge (approximately June, 
2011, btw), you're able to serve those customers without having to limit them 
to LSN/CGN/NAT64/etc. access to your services.

Hasn't been my experience doing a number of IPv6 migrations.
