Migrating an Intranet to IPv6
Best practices for migrating existing IPv4-based network infrastructures to IPv6 are still evolving. Therefore, this section presents a general outline on how to migrate an intranet to IPv6 and provides references to more detailed information on the subject for interested readers.
The ultimate goal of IPv4 to IPv6 migration is to achieve an IPv6-only network infrastructure that has IPv6-only hosts. From a practical standpoint, however, the lesser goal of achieving a network infrastructure that supports both IPv6 and IPv4-and where hosts also support both IPv6 and IPv4 but use mainly IPv6-is a more reasonable goal for which to aim. Achieving this goal is a lengthy process that involves seven main steps:
- Upgrading your applications and services
- Preparing your DNS infrastructure
- Upgrading your hosts
- Migrating from IPv4-only to ISATAP
- Upgrading your routing infrastructure
- Upgrading your DHCP infrastructure
- Migrating from ISATAP to native IPv6
