Upgrading the core service provider network to IPv6 is usually the easiest part of the puzzle. Access networks, network management and provisioning systems are the usual causes of major headaches.
If you're not using MPLS, you can deploy native IPv6 in your core network, running all core routers in dual stack mode, where they route IPv4 and IPv6 concurrently. If your core network uses MPLS, it's much better to use the existing MPLS infrastructure (more so if you use MPLS Traffic Engineering for load distribution or fast rerouting capabilities) and transport IPv6 across the MPLS core using the 6PE functionality (RFC 4798). You can also use MPLS infrastructure to create IPv6 layer-3 VPNs similar to IPv4 MPLS/VPN services with the 6VPE functionality (RFC 4659).
