Re: [Samba] upgrading DC 4.5.x to 4.7.x

why not simply add new DCs to current production domain?
Because we were facing corruption issues on the 4.5 DCs, upgrading those to 4.7 didn't work out.

corruption/replication issues on 4.5 production servers between each 4.5 before try to upgrade?
I have an old 4.1 DCs with "internal dns inconsistent" status now.

 We tried, but faced replication issues, and
commands like samba-tool drs showrepl no longer showed any output, or python errrors and timeouts. Also fsmo transfer failed with timeout issues.

Ok, I understand, thanks for the clarification.

I'm thinking about way to upgrade too, but using "separated environment"
Just a different VLAN with only the DCs.

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

After some practising and taking notes, I could do it in just a few hours for our three DCs. :-)

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...
