  • Hi

     You should configure Dhcp server on target domain for clients.Also you can migrate dhcp to target domain,

    It depends on your definition of "issues"  As long as you don't any restriction on your network (for example, IP Helper Address), client will/can get IP address from your old DHCP server.  Make sure to update the DHCP scope with your target domain DC as the DNS server or additional DNS.  You may need to re-consider this strategy, if your DHCP is registering computer objects in DNS (on the behalf of the computer)

  • Hi Hebbar11,

    >>Shall i face any issue? how client will take the IP. 

    After migration, if your source domain is offline or no longer used, the next time(e.g. restart) the DHCP client trying to connect to the DHCP server, the communicate will be fail and clients will get an address of 169.x.x.x.

    If your source domain is still used, and you assign a new computer for the domain with the same ip address and the same DHCP configurations I suppose things will continue to work.

    Just migrating the old computer to the new domain, then configure a new IP address for it.

    For more info, I suppose the how dhcp works could give you more helps:
