Move DNS from Forest A to Forest B domain RRS feed

  • Question

  • Hi,

    Currently, we have 2 forests

    Forest A with DNS of jimmy.com and Forest B with Johnny.com

    Forest B has conditional forward for jimmy.com to go the DC of jimmy.com

    what is the best way to move jimmy.com Zone to Forest B and remove the conditional forest.  The  idea is eventually to get rid of Forest A completely and run off only Forest B domains.

    Thanks for you time on this question

    >> what is the best way to move jimmy.com Zone to Forest B and remove the conditional forest.

    You could follow the steps below to move zone by DNSCMD tool:

    1. run command dnscmd /zoneexport domainname to export the data of jimmy.com zone, and the path is “system\dns\backup\domainname.com.dns.bak”
    2. on the forest B, you could recreate a new zone, and perform the command dnscmd/zoneadd to load the data file of jimmy.com zone.

    Here is reference about description of tool DNSCMD for you:

  • thanks for that info, that will work great.  what will happen if there is a conditional forward and a zone created for the same zone, will it look at  the zone first before it goes out the conditional forward?

    would I import the zone first, then delete the conditional forest and once that is working successful I would then break the AD trust between the two forests.

    No, it won't, DNS server will look at the zone first before forward has forwarded.

    Conditional forward will only forward query with specific conditions.

    >>would I import the zone first, then delete the conditional forest and once that is working successful I would then break the AD trust between the two forests.

    Yes, you could.

    Best Regards
