corruption/replication issues on 4.5 production servers between each 4.5

Ok, I understand, thanks for the clarification.

different VLAN, but with same addresses/network mask? without gateway 
with main network, ok.

i.e. you can try free in diffrenet vlan for some time (restore, try, 
delete and next attempt), and, when ready, start replacing new copy of 
production domain? ok...
