3. And third, prioritize. You don't need to do a forklift upgrade or replace every IPv4 address with an IPv6 address across the entire organization all at once. Rather, focus on one goal at a time. The most important piece is your Internet-facing applications (primarily Web and email). You'll want to make sure you don't lose your Internet presence as IPv6 users come online across the globe. Next, engage your organization's desktop team to ensure internal user workstations are transitioned to IPv6 so they can access the Internet and business partners over IPv6. Once these two milestones are complete, you will be in good shape and can slowly but surely transition the rest of the infrastructure and internal applications to IPv6 at your convenience.
