Nexus 9K - Jumbos + vPC?

Apologies if this is newb level material, but just wondering if there is any reason Jumbo Frames support would prevent my network team from also using vPC to form an LACP based LAG?

I know the 9K supports Jumbo and also vPC, just want to make sure there is no limitation when combining the two.

I found this document which also says I can enable Jumbos per port, which is very helpful as its only 2 servers at the moment who need Jumbos for their HCI inter-communications.

Thanks again

EDIT: Thinking about it further, is there anything special that needs to be done on the vPC Cross Connects to enable Jumbos? I'm sure some of this traffic will be crossing that connection unless there is some traffic pinning on the vPC I am not aware of.
