Cisco 3750x Rolling Stack Upgrade with LACP Uplink?

[sclebo05]

I have a question regarding rolling stack upgrade (rsu) on Cisco Catalyst 3750x switches.

Using this command:
archive download-sw /reload /rolling-stack-upgrade tftp://10.10.20.1/c3750e-universalk9-tar.152-1.E.tar

Rolling stack upgrade works if I have two uplink rsu ports defined, one as 'rsu active' and another as 'rsu standby'. My question is how do I achieve the same result in the case of using a cross-stack LACP uplink? In that case, can I configure LACP member ports with these commands, or will they be kicked out of the Etherchannel for not matching the parent config?

OR

Is it best to NOT use LACP bonds for uplink in this case, but rather individual uplinks with the rsu command on them?

After going a few rounds with Cisco TAC, the final answer was "don't use LACP to uplink". Instead, use 2 separate uplinks with the appropriate rsu commands.
