Cross Stack Ether channel Between 3750 and 6509-E


I want to know that it is possible to create a Cross-stack ether channel between cisco 3750 switch and 6509-E chassis.

our 3750 is having ios Version 12.2(25)SEE4 and on 6509 I am having a VSS and it is Quad-sup in chassis with sup vs-s720-10-G and ios version is 12.2(33)SXJ3.

So,please let me know that can we create it between both the 2 chassis and 3750 i.e according to 6509 it is multi-chassis ether channel.

It should be possible, although that's a very old IOS for your 3750.  Would recommend (55)SE9.
