Can I put two cameras (5D2, 5D3) on the same card?

Is it possible to swap the card I am using between a 5D2 and a 5D3 without any problems?  I have one large high speed card only.

No

You could potentially do this, but I've not tried:  put ML 5d2 on the CF card, and since the 5d3 supports both CF and SD, put the ML 5d3 on the SD.  You'll be fine on the 5d2, but need to always make sure you boot from the SD without the CF in the 5d3, then you can use the CF as just a storage card?  Maybe?  I don't have a 5d2 to test.

and by 'boot' and use the other as storage I mean you need to keep the CF card OUT of the 5d3 on boot, and then after it has loaded ML, put in the CF after that
