Using 3210 c0a for controller swap

[ Edited ]

I am in charge of a controller swap from a 3210 7-mode to 8020 7 mode.  The 3210 is using the backplane for HA, but has the C0a/C0b open.  I need a connection between chassis since the 8020 is the same configuration with 2 controllers in one chassis.  If I use netapp 10GbE cables will the 3210 switch to the "C" ports if it sees a link?  I'm not finding any information to support this scenario.

cannot say for sure but I assume that if the 2 controllers are in the same chassis, the interconnect link will go through the backplane (regardless of the 10G link in the c0a/c0b ports) but once you remove one of the controllers from the chassis, the link will start working through the 10G link

I've found that the bigger is likely that there doesn't seem to be a way to swap controllers "live" or "hot" as they say..
