Before we start talking about upgrading a previous versions of Active Directory to Windows Server 2016
or higher I have to mention that when you demoed ADT as domain controllers that are running Windows
Server 2012 R2 2012 two thousand eight are two and two thousand eight.
The metadata in 80 Days and the obsolete DNS records are not removed automatically.
You have to address this manually or use scripts.
Addressing this issue is not necessary.
When an in place upgrade is taken place now to a greater previous version of 8 it s to Windows Server
2016 ADT yes you can use either of following two methods you can upgrade the operating system of the
existing domain controller as two Windows Server 2016 or you can introduce Windows Server 2016 as domain
controller in the existing domain you can then decommission eight it is domain controllers that are
run in earlier versions of Active Directory of these two methods.
The second is preferred because upgrading operating systems especially on servers that have been running
for several years is often difficult because of all the changes made through the years by installing
new domain controllers that are running Windows Server 2016 it will have a clean installation of Windows
Server 2016 you can deploy Windows Server 2016 servers as member servers in a domain with domain controllers
that are running Windows Server 2008 or newer versions.
However before you can install the first domain controller that has run and Windows Server 2016 you
must upgrade the schema inversions of 80 days prior to Windows Server 2012.
Our 2 You ran that at prep that exit tool to perform scheme upgrades.
However when you deploy new Windows Server 2016 domain controllers in an existing domain and if you
are assigned and with an account that is a member of schema admins and enterprise segments group the
Active Directory Domain Services configuration wizard automatically upgrades the HDD forest schema.
Please know that Windows Server 2016 still provides a 64 bit version of ADD prep so you can run at prep
that exist separately.
For example if the administrator who is installing the first Windows Server 2016 domain controller is
not a member of the enterprise admins or schema admins group.
You might have to run the command separately.
You only have to run at Prep though to see if you're planning an in place upgrade for the first Windows
Server 2016 domain controller in the domain.
So the upgrade process consists of four steps to upgrade the operating system over Windows Server 2012
are two Domain Controller two Windows Server 2016 performs the following steps.
Insert the Windows installation media for Windows Server 2016 and then run set up on the choose what
to keep page select keep personal files and apps and then click Next Step 3 is that on there what needs
your attention page.
Read the notice that Windows server upgrades are not recommended.
Then click on forum and then click refresh and on the ready to install page click install the server
will restart several times while the Great is in place.
Keep in mind that with this type of a great edit the s on the domain controller is upgraded to Windows
Server 2016 HDD apps as a best practice.
You should check for hardware and software compatibility before you perform an upgrade after performing
the operating system upgrade.
Remember to keep your drivers and other services such as monitor run agents and also check for updates.
For both Microsoft applications and non Microsoft software.
Please know that you can upgrade directly from Windows Server 2012 and Windows Server 2012 our two to
vendors Sara 2016 to upgrade servers that are running a version of Windows Server that is older than
Windows Server 2012.
You must either perform an interim upgrade to Windows Server 2012 or 2012 our two or you must perform
a clean installation.
Note that Windows Server 2016 8 it is domain controllers can co-exist as domain controllers in the same
domain as Windows Server 2000 eight domain controllers or newer.
Now as for the clean installation process it takes three steps for clean installation of Windows Server
2016 as a demand member.
You have to run these steps first deploy and configure a new installation of Windows Server 2016 and
then join it to the domain.
Second use or manager to get the Active Directory Domain Services role.
And the third step is that you have to promote the new server to be a domain controller and the domain
by using the Active Directory Domain Services configuration wizard.
