cnMaestro upgrade with OVA


We are planning to upgrade our cnMaestro from 3.1.1 to 3.2.0 and further. As we are global, there is no ideal time to do it “after hours” as with different time zones, there is always an office with working employees. Question, will our Enterprise APs and Cnmatrix switches work with their current config when cnMaestro will be down? Thanks.
