In this part of our Active Directory journey we will talk about the operations master roles FSMO and Forest and domain functional levels. Microsoft, in attempting to create a multi-master model for the AD database, one where every copy of the database was exactly the same, and there was no single master where everyone pulled their content from, realized that a small subset of the activities of AD could not be made multi-master. Some of these things worked best, or worked at all, when a single computer was responsible for the execution of that task. In Multi-master model changes can occur at any dc which can lead to conflicts and issues once the data is replicated to the rest of the dcs.

Windows server was released for public GA on mid oct Its exciting time as businesses are already working on migrating their services in to new windows server infrastructures. In this post, I am going to explain how you can migrate from active directory running on windows server R2 to windows server active directory. The same steps are valid for migrating from windows server , windows server R2 and windows server I setup windows server and already added to the existing domain.
I want to upgrade this to Exchange as well. Thank you for the step-by-step. I have a question slightly different from another that you had answered. I have a small network. I would like to migrate AD to a new Server system while at the same time leaving Exchange on the existing server.

I have a question.. We had distributed FSMO roles on different different servers, like forest wide on root dc, and domain wide roles on child DC. So now I need to migrate windows R2 to So Where i need to deploy first server and which roles i need to migrate Like is there any sequence of FSMO roles migrations?
Let me know. Great tutorial, Please i want to know if the workstations previously joined in the decomissioned domain controller will still authenticate and work seamlessly without further work on them. Also is it advisable to decomissioned the domain controller immediately after upgrade in a bit to move to higher functional level as stated here without waiting for a week or so to ensure everything works fine.

As most of you were aware, I published my book "Mastering Active Directory" back in, When I released it, I had my doubts! It was my first book even though I was writing to blogs for many years. Active Directory Windows Server October 23, by Dishan M. Francis 23 Comments. Current domain and forest functional level of the domain is windows server R2. Install Active Directory on windows server Log in to windows server as domain administrator or enterprise administrator.
Run servermanager. Then click on Add Roles and Features. It will open up the wizard, click next to continue. In next window keep the default and click next. Roles will be installed on same server, so leave the default selection and click next to continue.
Under the server roles tick on Active Directory Domain Services , then it will prompt with the features needs for the role. Click on add features. Then click next to proceed.
On the features windows keep the default and click next. In next window, it will give brief description about AD DS, click next to proceed. Then in next window it will give brief description about configuration and click on install to start the role installation process. Once installation completed, click on promote this server to a domain controller option. It will open up the Active Directory Domain Service configuration wizard, leave the option Add a domain controller to existing domain selected and click next.
In next window define a DSRM password and click next. In next window click on next to proceed. In next windows, it asks from where to replicate domain information. You can select the specific server or leave it default. Once done click next to proceed. You can change the paths or leave default. In demo, I will keep default and click next to continue. In next windows, it will explain about preparation options.
Since this is first windows server AD on the domain it will run forest and domain preparation task as part of the configuration process. Click next to proceed. In next window, it will list down the options we selected. Then it will run prerequisite check , if all good click on install to start the configuration process. Once the installation completes it will restart the server. I assume by now you have idea what is FSMO roles. If not search my blog and you will find article explaining those roles.
One is using GUI and other one is using command line. If you like to use GUI mode search my blog and you will find articles on it. Then type netdom query fsmo. This will list down the FSMO roles and its current owner. Now we moved FSMO roles but we still running system on windows R2 domain and forest functional levels.
In order to upgrade it, first we need to decommission AD roles from existing windows server R2 servers. It will ask for local administrator password. Upgrade the forest and domain functional levels to windows server Now we have the windows server R2 domain controllers demoted, next step is to upgrade domain and forest functional levels.

5 FSMO Roles in Active Directory
Choose a Session. Active Directory , Data Security. Jeff Petters. Active Directory AD has been the de facto standard for enterprise domain authentication services ever since it first appeared in late in Windows Server There have been several enhancements and updates since then to make it the stable and secure authentication system in use today.
Understanding Operations Master Roles (FSMO) / AD Functional Levels
Windows Server Brain. Transferring a FSMO role to another system is a rather painless process. Because all of the domain controllers within a domain have identical data within the Active Directory database, when you transfer a FSMO role, you are simply changing a flag that specifies that one domain controller can control the master operation and the other cannot. Seizing a FSMO role has serious implications. If you are going to take this drastic step, you must commit yourself and make sure that the original role holder is never reintroduced onto the network. Reintroducing it could cause serious problems within your Active Directory infrastructure. The following sections discuss the methods you can use to identify the systems that currently hold the master operations roles, and the methods you can use to make sure the domain controller identified as the standby server can take over a role.
