Tomahawk and Typhoon on IOS-XR 64-bit

XR fam,

 

We have a few ASR 9006 chassis that are currently running some MOD-80s (Typhoon) for 1- and 10-Gig MPAs plus some 100G line cards (like the A9K-1x100GE-TR). Some of the 100G line cards have 40-kilometer ER4 optics in them (CFP-100G-ER4). We are trying to budget for some line card upgrades and plan on using MOD-200 (Tomahawk) blades with 100G MPAs (like A9K-MPA-1x100GE or A9K-MPA-2x100GE). According to Cisco's optics compatibility matrix, the 40-kilometer optic that works in those MPAs is the CFP2-100G-ER4. Also according to that matrix, that optic requires 64-bit IOS-XR code. We've seen mention in other documentation that Tomahawk and Typhoon line cards will not work in the same chassis on 64-bit code. Is this true? Will we need to upgrade all of our MOD-80s to MOD-200s for our 1- and 10-G ports in order to use those CFP2-100G-ER4 40-kilometer optics? We wanted to verify with the community that this is a hard-and-fast caveat, or if there are exceptions.
