Moving a Windows Server 2012 R2 Installation to a new server! RRS feed

  • Question

  • Hi all, I am hoping to get some support on this. At the moment we have a server running Windows Server 2012 R2 on a pretty old machine, it isn't even a real server it was a PC that has been turned into a Server!

    It is starting to get a bit older and BSOD'ing due to hardware related problems so I believe that now is a good time to upgrade! 

    We are going to be purchasing a Dell Poweredge T110 II and moving everything across. I have never actually performed a migration before so I am a little concerned about what is the best way to do it?

    We are keeping Windows Server 2012 R2 so I can reinstall that on the new server if necessary and then move everything across?

    There are only about 10 users and 300GB of data. The server has the following functions:

    - Active Directory
    - DNS
    - DHCP
    - File Sharing/Network Shares
    - Group Policy etc
    - Print Sharing

    My first thought was to use Windows Server Backup and do a bare metal backup and restore it to the new server but somehow I don't think this is the best way to go about doing what I want to do.

    Can someone point me in the right direction to migrate everything across?

    The old Server is still fully functional at the moment just incase that is important on the way this is done.

    Thanks muchly!

  • I was wondering in regards to moving DNS, AD etc from one server to another, when I get the new server setup, can I just promote the new server to a domain controller and then once I am certain that all is working, can I just demote the old server? I can then ensure DNS is setup correctly etc...



    I'd follow Meinolf's page for the detailed migration from old to the new. Basically you'll standup the new one, patch it fully, join it to the existing domain, then promote it.

  • As far as migrating AD/DNS/DHCP/File Shares/GP:

    This can be done over time.

    Turn up new server

    Add it as a member of the domain (validate static DNS of old domain controller)

    DCPromo or Features and Roles Install Active Directory Domain Services

    Add it to the existing Domain as a GC

    let it replicate and reboot.

    DNS is installed automagically. You may need to do some tweaks in your environment:

    Check scanners/copiers for DNS and scan to locations

    Phone/Fax/computers/appliances for static DNS

    Any applications that use static name of your DC should point to the domain EX:(DOMAIN.LOCAL)

  • Hi

     First of all,File sharing role run on a DC is not right configuration,i recommend you configure file sharing another member server,

    Maybe this topology is pratical for your environment;If you install Windows Server 2012 r2 Standard on Physcial server,you could install 2 virtual server with lincence on hyper-v role.

    - Install Windows Server 2012 r2 on pyhscial server,(i guess you have standard edition)

    - Confgure Hyper-v role on this physcial.

    - Install server 2012 r2 and add as an Additional Domain Controller;(VM)

    Server 2012 r2 ADC;

    https://technet.microsoft.com/en-us/library/jj574134.aspx

    - Then Transfer fsmo roles to this new server 2012 r2

    transfer fsmo roles;

    https://www.interworks.com/blogs/ijahanshahi/2014/01/20/transferring-fsmo-roles-another-active-directory-controller

    - Migrate DHCP to this new server.

    - And install another server 2012 r2 and add domain as an member server then migrate file shares from old server to this new server.(VM)You could migrate using ROBOCOPY,

    Robocopy;

    https://technet.microsoft.com/en-us/library/cc733145.aspx

    Also configure print share on this member server.

    - Finaly demote this old server from domain and will do a metadata cleanup.

    Metadata cleanup;

    Also make sure AD DS,DNS,AD site and services,DFS records updated.

  • I am not in a position to start configuring Hyper-V, multiple visualized servers etc. 

    The idea is for me to make this as easy as possible so that there is very little that can go wrong! 

    Like I said there are about 10 users tops, usually only 2 or 3 on at any one time.

    I just simply want to move everything over/migrate everything in the best way possible.

  • Agree, the AD/DNS role should run by itself on a single physical or virtual server. Also best to always have to DCs for redundancy. That being said;

    For the AD/DNS migration you can follow along here.

  • Okay, so I am thinking when we get the new Server I install the Hyper-V roll and install the DC as a VM. I will put file sharing onto a separate instance.

    I was wondering in regards to moving DNS, AD etc from one server to another, when I get the new server setup, can I just promote the new server to a domain controller and then once I am certain that all is working, can I just demote the old server? I can then ensure DNS is setup correctly etc...

    If this is a valid method, is there anything else I will need to check in order to ensure this will work?

    Thanks very much!

  • As great as it is to have multiple servers some people just can't do it. Either expense, space, power, cooling or technical know how.

    Nothing wrong with that.

    Microsoft's best practice would be to have a separate VMs/physical servers for every resource you would like to share.

    All of these services although not ideal could go on a single server. Your environment is small enough to support that. Only question that would go back to management is how long could this all afford to be down?
