Migrating from windows server 2008R2 to windows server 2012

Hi,

I have windows server 2008R2 and I got a new windows server 2012. How I can migrate all users from old to new server. The new server will replace the old server (same domain controller).

Also, I have backup domain controller which is now connected to windows server 2008R2. when I migrate from server 2008R2 to server 2012, how I can connect the old backup domain controller to be backup domain controller to server 2012?

Also, the domain controller is a print server. Is it possible to migrate all printer to a new domain controller or I have to install all printer again? If I have to install all new printer again on a new server how I can deploy them to all users? there is no way I can move to all users and install the sharing printer for them.

Also, Is it possible to migrate the folder sharing?

Thx

How I can migrate all users from old to new server.

when you promote the new domain controller, it will automatically replicate AD/DNS info from one of the other domain controllers

how I can connect the old backup domain controller to be backup domain controller to server 2012?

you don't; it is part of the same domain and replicates AD/DNS changes between each other

Is it possible to migrate all printer to a new domain controller or I have to install all printer again?

you can migrate

If I have to install all new printer again on a new server how I can deploy them to all users?

use group policy.  i just did this recently with print management

Do you have licensing for Windows 2016? Windows 2012 and 2012 R2 lose support October 2023, which is only 5 years away. It is about to enter extended support. Windows 2016 is good until January 2027.

Hi,

Thank you for your reply.  I am getting a new hardware server including windows server 2012. I am not promoting the same server. Also, I will use the same domain controller name.

Thx

I have windows server 2008R2 and I got a new windows server 2012. How I can migrate all users from old to new server. The new server will replace the old server (same domain controller).
What do you mean by this?  Is the server you are replacing a domain controller or a member server?  Are you replacing the domain controller?  Do you only have one server?  What exactly are you doing and what exactly do you have?   And please try to use proper terminology - it will help clarify things and make sure we give you accurate information.  Using wrong terminology can result in bad advice and misunderstandings.

Also, I have backup domain controller which is now connected to windows server 2008R2. when I migrate from server 2008R2 to server 2012, how I can connect the old backup domain controller to be backup domain controller to server 2012?
What do you mean a backup domain controller?  In Active Directory all domain controllers are just that, Domain Controllers.  I assume this means you have two DCs?  If you mean you have two DCs and you are replacing one, then you would install the new server as a new member server and add Active Directory by promoting it to be a domain controller.

Also, the domain controller is a print server. Is it possible to migrate all printer to a new domain controller or I have to install all printer again? If I have to install all new printer again on a new server how I can deploy them to all users? there is no way I can move to all users and install the sharing printer for them.
There is a tutorial for how to migrate printers here:
https://blogs.technet.microsoft.com/canitpro/2013/06/16/step-by-step-migrating-print-servers-from-windows-server-2008-to-windows-server-2012/

You can also deploy your printers via Group Policies.

Also, Is it possible to migrate the folder sharing?
There are a variety of ways of doing this.  And Windows Server 2019 will add another.  You can read about the current options by reviewing my article on the topic:
https://www.experts-exchange.com/articles/29316/File-Server-Migration-Methods.html

I am getting a new hardware server including windows server 2012. I am not promoting the same server.
You are buying a NEW server or a USED server?  As far as I am aware, 2012 is no longer sold with new servers - it's more 6 years old.  It's also a very bad idea to purchase a server license preinstalled WITH hardware.  You can never move that license and by purchasing 2012, it will be no longer supported in just 3.5 years.  VERY BAD IDEA.  Even if you MEAN 2012 R2, that only buys you 2 more years - 5.5 years and the software is out of date.  This just doesn't seem well thought out.  At a MINIMUM, if you have some business need to use 2012, you should STILL be purchasing 2016 via volume license and then you would use downgrade rights, media, and keys to install the older version for now and at least you'd have the license (a TRANSFERRABLE license) to upgrade to 2016 at a later date.

Also, I will use the same domain controller name.
This is a bad idea and complicates your installation process.  If this is a member server, renaming the server is easier.  If this is a domain controller, it's tricky at best and widely considered unwise by most professionals.  The ONLY way you should be doing this IF this is a domain controller is by demoting the existing domain controller that you're replacing, then renaming the old one.  Once that's done, you rename this one to the old name and THEN you promote it as a DC.  That is by far your BEST option if you really must keep the name the same.  If your network was setup appropriately to begin with (using long existing technologies such as group policies and distributed file system, then keeping the same server name would be of little importance because you would be able to easily and quickly update the workstations with the location of the new resources.

If you don't understand these recommendations and how to implement them, then I would strongly recommend you contact and partner with a professional who can help you get this done right the first time.

Thank you. I am sorry if my question is not clear to you. Also, please, I am not asking if this is a bad or good idea. This hardware and software that I have.

I have windows server 2008R2 and I got a new windows server 2012. How I can migrate all users from old to new server. The new server will replace the old server (same domain controller).

I think its very clear. I have hardware installed with windows server 2008R2 and I got new hardware with installing with windows server 2012

Also, I have backup domain controller which is now connected to windows server 2008R2. when I migrate from server 2008R2 to server 2012, how I can connect the old backup domain controller to be backup domain controller to server 2012?

Also, this question is very clear. when you install AD there and add another server I have the chose to add this server to the new forest or existing forest.

Also, I will use the same domain controller name.

This is not a member of DC its the main DC. let's say my old server domain is (test.com) I will need the new server to have the same name (test.com)


Thx
kevinhsieh

You add new server to the existing domain. The domain name will always be the same. The domain controller name fully qualified domain name (FQDN) should be something like dc1.test.com, or preferably dc1.ad.test.com, with the Active Directory domain name being ad.test.com, which is a DNS sub domain of your public test.com domain.

If you really really want to keep the FQDN of the new DC to be the same as the old, the only safe way is to start off with at least 2 domain controllers. That way you can demote the old DC and give it a new IP, take the new server and give it the original name before promoting it as a DC. Then migrate back DHCP and FMSO roles and give the new DC the original IP of the original DC.

Are you virtualizing? You should be. You get an extra Windows Server license to run on the same hardware for free, and future migrations are easier.

Hopefully you are actually getting Windows 2012 R2. Windows 2012 is annoying to work with in all the same ways Vista was.
