Oggetto: Change IP to DC 

hi . 
a DC server has been physically moved to another site and network, without notify me! 

So now I have the new DC with different ip address. 
This DC is part of multi DC Domain Enviroment. 

I tyried to follows this instruction : https://wiki.samba.org/index.php/Changing_the_IP_Address_of_a_Samba_AD_DC 

It can ping the other DC's : 
root at exme-dc:~# ping dc1.wdc.DOMAIN.it 
PING dc1.wdc.DOMAIN.it (172.32.1.6) 56(84) bytes of data. 
64 bytes from 172.32.1.6 (172.32.1.6): icmp_seq=1 ttl=62 time=23.0 ms 
64 bytes from 172.32.1.6 (172.32.1.6): icmp_seq=2 ttl=62 time=22.6 ms 
^C 

but when trying to demote I get ( expected ) error: 

root at exme-dc:~# samba-tool domain demote -U administrator 
Using dc1.wdc.DOMAIN.it as partner server for the demotion 
Password for [WDC\administrator]: 
Deactivating inbound replication 
Asking partner server dc1.wdc.DOMAIN.it to synchronize from us 
Error while replicating out last local changes from 'CN=Schema,CN=Configuration,DC=wdc,DC=DOMAIN,DC=it' for demotion, re-enabling inbound replication 
ERROR(<class 'samba.NTSTATUSError'>): Error while sending a DsReplicaSync for partition 'CN=Schema,CN=Configuration,DC=wdc,DC=DOMAIN,DC=it' - (3221225653, '{Device Timeout} The specified I/O operation on %hs was not completed before the time-out period expired.') 
root at exme-dc:~# 

Any suggestion how to workaround this situation? 
thank's
