Catalyst 65xx Sup Engine upgrade question

[floridomd]

We have a bunch of old stuff on the network than needs to be replaced or upgraded.  Some of our 6500s are using the SUP720-3B, and we're considering upgrading to the VS-2T-10G.    The white paper indicates that the 2T SUP is backwards compatible for the 67xx line cards, but then it mentions swapping out daughter cards.  So my question is as follows:

Is the 2T Sup Engine backwards compatible with the 67xx line cards the way it ships, or do I need to purchase an additional daughter card to make sure that it will function with the existing 67xx line cards?

In case it matters, here is a listing of some of the line cards:

WS-X6748-GE-TX CEF720 w/WS-F6700-CFC

WS-X6748-SFP CEF720 w/WS-F6700-CFC

WS-X6724-SFP CEF720 w/WS-F6700-CFC

Thanks

According to the Q&A, it is compatible:

Q. I have Cisco 6700 Series line cards today with Centralized Forwarding Cards (CFCs). Are these line cards supported in a Cisco Supervisor Engine 2T system?

A. A Cisco Supervisor Engine 2T system will support all Cisco 6700 Series line cards with CFCs.

There is also an option to upgrade CFC to DFC.

Hi

The sup2T will work with 67xx cards with CFCs or DFC4s.  The one problem card is the 6708, which has a non-changable DFC3.
