Upgrade AD 2003 to 2016

    Question

  • Hi Guys

    I need to upgrade an existing Windows Server 2003 to 2016 and need some advice,

    1. Can we do an in-place upgrade?

    2. If we need to do a side by side upgrade what would be the upgrade path of this?

    Thanks

  • In-place upgrade is not support nor is it recommended.

    Better to stand up the new one, patch it fully, join existing domain, add active directory domain services, promote it. When all is good then you can demote / decommission the old one.

  • Hi Dave

    Thanks for your response.

    How about if existing server 2003 is 32bit edition?Can i still directly bring in a 64bit Server 2016 and proceed with the upgrade and moving of roles etc?

  • If you asking about in-place upgrade then no it is not possible to upgrade any windows  32 bit OS to 64 bit. Introducing a 2016 DC in 2003 environment should not be a problem.

  • I agree with the others that in place upgrade is not possible. How many users are we talking about?

    One option can be like this:

    1. expand schema to support 2008, then introduce your first 2008 DC.
    2. After that once again you need to expand schema in order to support 2008 R2 and introduce your first 2008 R2.
    3. Move FSMO roles to your new 2008 R2 and demote and dump the old DC's.
    4. Extend schema one more time for 2012 R2 and introduce your first 2012 R2 DC.

    and continue until all your DC's are 2016.. This might take some time but this is one of the path I will follow which is called "Chain Migration" in my terms. :)

    Hi

     No,you shouldn't perform in-place upgrade(not recommended in-place upgrade on DC's),Even you can't migrate server 2003 to server 2016 directly,first you should migrate server 2008 at least.(functional level needs to be server 2008 at least for server 2016 migration.)

  • Hi!

    why you advice to first introduce a 2008DC and then 2012R2, in the link you passed it says that in order to install a domain controller 2012R2 the domain functional level must be 2003 or higher, so If you have a 2003DC, you should check that the DFL is 2003 and then you can introduce a 2012R2 without doing a 2008R2 installation.
