Cisco ACI Multisite software

[Lapta]

Good day,

I have cisco aci multisite deployment, site A and B. Site A & B are running in the same version which is version 5.2.6.

I need to upgrade site B only to its latest known stable version 5.2.8.

I have check everything for its compatibility hardware, NDO, cimc and everything is compatible.

As far as i read, there is no document telling that software version match is mandatory for multisite aci.

Is there anything that i need to concern about the differences software version between Site A and Site b?

Thanks in advance.

Site A and B don't need to be on the same exact version but it's preferred. You can run different versions for short periods of time specially if you want to take advantage of new features.
