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. > Putting your client machines (ie internal network) to IPv6 is relatively > easy.

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. > So my advocacy, is get your client (I'm not talking about customers here, but > client as client/server) machines on IPv6, get your engineers, support > staff,.. to be familiar with IPv6, then all together you can better > understand how to migrate your servers infrastructure to IPv6 (and your > customers to IPv6 if you are an ISP). > 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. > If you do that, you will see migration to IPv6 is made much easier, and much > faster. > Hasn't been my experience doing a number of IPv6 migrations.
