Do you actually require migrating to a "new" domain or are you looking to retire old hardware and replace it with new hardware?

Can you please give us an idea of what versions of Windows Server you are currently running, How many servers and the roles of each.

Any additional information you can provide will help greatly

What OS are you going from and going to?

Whats on your network, Exchange, SQL and file and print servers etc.

I have done several migrations but they all are different and dependent on what you have or in some cases haven't got.

Regards

We are migrating from xxx.yyy.com to zzz.yyy.com.  Most systems, with the exception of SQL and a QA server, are on Server 2003.  We also have 3 ESX servers which host most of virtual servers, with the exeption of our DC's which, for now, are physical servers.  One of our DC's has all the FSMO roles, which goes against M$ "best practice".  In addition, we have 1 additional ESX server which is used as a DR solution.  

There are also three sites which have their own DC as well.

To migrate to a new domain is a major task, even with a lot of planning.
You basically need to write off a complete day of business, and be able to accept disruption for a week or more. While it is possible to replicate a lot of permissions and other settings, getting them all is impossible.

If you are writing off the entire forest, then migration of some data has to be done by hand. For example in Exchange, you will lose all permissions on everything - public folders, mailboxes etc, so they will all have to be reset. The data will have to be moved via exmerge, which can be slow.

Last time I did one, it was planned for a month, took a week to build the new domain, a complete three day weekend to move the data, including two full overnights with a team change for the night shift. The Tuesday was a complete write off, the Wednesday was a partial write off. The company didn't really settle down until the next Monday. However the client said it was worth it, because the site was basically cleaned up and the ROI justified it.
