DNS/DHCP migration problem

I need to migrate my DNS/DHCP server off of the server that it is on and make it a server unto itself. But I'm having a little trouble figuring out the best course of action to accomplish this.

The following is a list of our servers (names abbreviated), and their relative location.

My site:
[INDENT]IS <---- (NW6.5SP7, Master of Root and CA)
IS2 <---- (NW6.5SP7)
BM <---- (NW5.1SP8, BorderManager 3.7)
FAX <---- (NW5.1SP8 with DNS/DHCP)
iWeb <---- (OES - Linux)
BKP <---- (NW6.5SP7)
ZEN <---- (NW6.5SP7, ZfD4.01)
iPrint <---- (NW6.5SP7)
[/INDENT]
Remote site:
[INDENT]IS <---- (NW5.1SP8)
BM <---- (NW6.5SP5, BorderManager 3.8)
DHCP <---- (NW6.5SP7)
IS2 <---- (NW6.5SP6)
[/INDENT]
The server in question is the FAX server at my site.

Due to a large number of devices and servers with static assigned IP addresses and DNS settings, I have decided that the easiest thing to do would be to have the IP address of FAX follow the DNS/DHCP server. This, of course, means that the IP address of FAX has to change at some point in this process.

I'm having trouble figuring out the order in which things should happen. Should I remove DNS/DHCP from the network at my site, change the FAX server's IP, then install DNS/DHCP back into my network with the old FAX IP?

Oh, and to make things even more complicated, the remote site does not have a DNS server. They use ours. This means that when I try to do an IP change on FAX there won't be any DNS server. Will eDir still sync?

Any thoughts on this process and links to helpful TIDs would be greatly appreciated.

Re: DNS/DHCP migration problem

If you will be moving this to new hardware - that's what it sounds like -
then why not just use the migration tookit.

Re: DNS/DHCP migration problem

This is not strictly a migration issue. The server is being split up. DNS/DHCP is being moved off of the current server, and taking it's IP address with it (but not the server name).

I need to know if I can re-IP the old server if DNS is not working and if eDir will still replicate that out.

Also, I need to know how to get DNS/DHCP working again on new box.

You can reassign the DNS/DHCP info to another server in the same tree
yes.

You mean "change the IP address", yes. But do not change both IP and
name at the same time.

Re: DNS/DHCP migration problem

So the procedure would be.....

  1. Make sure the tree is healthy.
  2. Export both DNS & DHCP to TXT files.
  3. Uninstall DNS & DHCP from the FAX server.
  4. Give the FAX server a new IP address.
  5. Verify eDir replication.
  6. Install new server with old FAX server IP address.
  7. Edit DNS & DHCP text files, replace all references of FAX (except the A record) with the name of the new server. Change the A record for the FAX server to it's new IP address.
  8. Install DNS & DHCP on the new server.
  9. Import the modified DNS & DHCP text files from the old NW5.1 server into the new NW6.5 server.Or am I making this more complicated than it really is?

Well, there is no need to uninstall DNS/DCHP, just do not load NAMED and DHCPSRVR. In The
NDS/DHCP console, juts assign the resources to the new server. Naturally you need to
change all affected names in DNS. Exporting, just in case is a good idea though.

Re: DNS/DHCP migration problem

So if I don't uninstall DNS/DHCP from the old server, then when all is said and done, I'm going to have to manually delete the old DNS and DHCP server objects from eDir. Right?

And I will have to do an actual install on the new server so that the new eDir objects get created. Right?

And then the zones and scopes get reassigned to the new server, and affected names should be revised.

Yes. You will have to go through and check manually.

I disagree, but maybe its just in how we're reading the question. In my
read of it, an install would try to create new Locator, group and
RootServerInfo objects, which is not necessary or desired here. All that
needs to be done is create the new DNS and DHCP server objects, then
assign the resources to them and load the respective NLMs.

From iManager or the DNS/DHCP console.

Re: DNS/DHCP migration problem

OK, I think I can formulate a plan of attack from this. Unless anyone has something to add or correct.

Thanks for the help guys.
