    In the same domain, 2 DCs with replication. Both are currently in 2000 mixed
    mode and I have to raise them to 2003 mode.

    1/ is it enough that I do it only on one of them and through replication the
    second will be automatically raised?

    2/ As I must do it on a production server, is there something to consider
    before, to be sure that all goes well?

    Thanks. Hubert

  2. Hello hretif,

    Before starting use the support tools to check that the domain is healhty:
    dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt
    netdiag /v >c:\netdiag.txt [from each DC, netdiag may work but isn't supported
    with Windows server 2008 and higher]
    repadmin /showrepl dc* /verbose /all /intersite >c:\repl.txt (if more then
    one DC exists)
    dnslint /ad /s "DCipaddress" (http://support.microsoft.com/kb/321045)

    If everything is error free make sure you have an up-to date- AD aware backup
    and then you can raise the functional levels. This has to be done through
    AD UC, AD domains and trusts and the Schema management console if you use
    the GUI way. For command line it can be done with ntdsutil:

    Best regards
