Migrating NT 4.0 to Windows 2003 Active Dir
Posted on 2004-10-06
I have 3 bdcs and 1 pdc on nt 4.0 domain with separate nt 4.0 and exchange 5.5 server.
What i am wondering is what people usually do in this case.
We are 500 users company with single domain.
I would like to migrate to a fresh domain rather than doing upgrade to AD.
My concern is that current comain is called domainNT and i would like to change it to match our dns name.
How will that impact each machine. I know how to export usres from nt4.0 and import them to ad, but what can be done with computers.
Will each pc in the corp have to be rejoined to the new domain and each users profile on local machine will have to be redone.
How do other peple deal with this issue. Also, how is exchange handeled. Do you upgrade os first to win2k and than exchange since exch 5.5 does not run on win2ks what are my options. Exchange server is not domain controller. Do i just build another temp box migrade 5.5 users and than rebuild the old 5.5 box with new os and exchg 2k3 and migrade users back from temp box?
