Migration Active directory

it's possible to migrate AD from Windows server 2003 to Windows server 2012 R2 ?

I believe that you mean upgrading to Windows Server 2012 R2. If that is the question then you can do it with no problems.
The requirement is to have at least Windows Server 2003 as Forest Functional Level. You can raise it as mentioned here: https://technet.microsoft.com/en-us/library/cc730985.aspx
Once done, you can simply add a new server running Windows Server 2012 R2 and promote it as an additional DC with DNS and global catalog. Forest and Domain preparations are done automatically. At the end of the operation, transfer FSMO roles to the new DC
and make sure that time sync is properly configured: http://social.technet.microsoft.com/wiki/contents/articles/18573.time-synchronization-in-active-directory-forests.aspx
Of course, before promoting a new DC or demoting and existing one, you need to make sure that your DCs and AD replication are okay using
dcdiag and repadmin commands. Also, take a system state backup of at least one DC with GC before starting with changes.
Once you added your new Windows Server 2012 R2 DCs and everything is okay, you can demote your old DCs. Once all your DCs are running Windows Server 2012 R2, you can raise your DFL and FFL to Windows Server 2012 R2 and take benefit of the new AD features:

Migrate Active Directory 2003 to 2012 R2 and Exchange Server 2007 to 2013.

My question is which one need to migration first. Active Directory 2003 to 2012 R2 and FFL & DFL or Exchange Server 2007 to 2013.
Md. Ramin Hossain

My question is which one need to migration first. Active Directory 2003 to 2012 R2 and FFL & DFL or Exchange Server 2007 to 2013.
Domain. For Exchange installation and upgrading to 2013, you need to make sure that your domain controllers can understand attributes of exchange 2013. Besides if you have DC/Exch on the same server which is 2003 is not supported. Because Windows Server
2003 is not supported.
Migrate your domain to at least 2008 R2 and then proceed with Exchange 2013.

Migrate Active Directory 2008 to 2012 but need to keep the same ip address and server name

Hi,
Current setup is 2 DCs in one site running 2008 R2 AD.
We are planning to migrate from 2008 R2 to 2012 R2 but need to keep the same ip address and server name. I have came up two plans to do this and hope someone can tell me which one would be the best approach. What is the pros
and cons in Plan A and B or may be plan C if there is a better one?
First, I was planning to do plan A but just had a second thought of Plan B. My concern in Plan A is about changing the server name when the new 2012 R2 already running as DC. Plan B would be changing all the old server
name and ip before they become member sever and DC.
Any information and suggestion would be very appreciated.
Plan A
Run adprep /forestprep on 2008 R2 DC
Build a new 2012 R2 server and promote it as 3rd DCs in current Domain
Transfer FSMO from 2008 R2 to 2012 R2
Run Repadmin /syncall to force replication
Rename the demoted 2008 R2 DC to something else
Change the demoted 2008 R2 ip address to something else
Restart the demoted 2008 R2 server to take effect
Now, run Netdom computername command to change the new 2012 R2 server name to the old 2008 R2 DC server name
Change the new 2012 R2 DC's ip to old 2008 R2 DC's ip
Run ipconfig /flushdns
Run ipconfig /registerdns
DCDIAG to see any error
Plan B
Build 2 new 2012 R2 standalone servers
In 2008 R2 ServerA transfer FSMO to 2008 R2 ServerB
Demote 2008 R2 ServerA to become member server
Rename 2008 R2 ServerA to something else and change the ip address to something else and shut it down
Now, rename one of the new 2012 R2 standalone server to the old demoted 2008 R2 ServerA name
Change the new 2012 R2 standalone server ip to the old demoted 2008 R2 ServerA's ip address
Add the new 2012 R2 standalone server (now with the old 2008 R2 ServerA name and ip) to become member server
Run adprep /forestprep on the 2008 R2 ServerB
Promote the new 2012 R2 (now with the old 2008 R2 ServerA name and ip) as DC
Transfer 2008 R2 ServerB FSMO to the new 2012 R2 DC (now with the old 2008 R2 ServerA name and ip)
Demote 2008 R2 ServerB as member server
Rename 2008 R2 ServerB to something else and change the ip address to something else and shut it down
Now, rename the 2nd new 2012 R2 standalone server to the old demoted 2008 R2 ServerB name
Change the new 2012 R2 standalone server ip to the old demoted 2008 R2 SeverB 's ip address
Add the 2nd new 2012 R2 standalone server to become member server
Promote it as DC
Run DCDIAG to check error
Thanks.

Hi,
Renaming a Domain Controller is a risky operation which may lead to issues, therefore, I would suggest you go with the Plan B, rename the server before it becomes DC.

SBS 2008 to Server 2012 R2 Active Directory Migration

Is there a tool that i can use to migrate Active Directory from SBS 2008 to Server 2012 R2?

There is no special tool for your situation. While there is a tool called ADMT that you may see mentioned if you search enough, it isn't really well suited for what you want.
With that said, there is also no *need* for a tool as I've already said. Nor do you need to recreate the users and have mismatched SIDs. You will add the 2012 machine to your existing domain and make it a domain controller. Yes, that means you will have
two DCs (for a time.) This is how larger organizations handle multiple DCs all the time, and they obviously don't go and create the same user on each DC. That is where the domain replication comes in. Your new server will be a DC and will replicate
all of the users *and* SIDs from the existing SBS server.
Then, when you are ready, you decommission the SBS 2008 server gracefully and the new 2012 server becomes your sole DC, but has AD completely intact. It is a tried and true practice, both within and outside of the SBS world, and has been done many many times.

Active Directory domain migration with Exchange 2010, System Center 2012 R2 and File Servers

Greeting dear colleagues!
I got a task to migrate existing Active Directory domain to a new froest and a brand new domain.
I have a single domain with Forest/Domain level 2003 and two DC (2008 R2 and 2012 R2). My domain contains Exchange 2010 Organization, some System Center components (SCCM, SCOM, SCSM) and File Servers with mapped "My Documents" user folders. Domain
has about 1500 users/computers.
How do u think, is it realy possible to migrate such a domain to a new one with minimum downtime and user interruption? Maybe someone has already done something like that before? Please, write that here, i promise that i won't ask for instruction from you,
maybe only some small questions :)
Now I'm studying ADMT manual for sure.
Thanks in advance,
Dmitriy Titov

Hi Dmitriy,
I got a task to migrate existing Active Directory domain to a new froest and a brand new domain.
How do u think, is it realy possible to migrate such a domain to a new one with minimum downtime and user interruption?
As far as I know, during inter-forest migration, user and group objects are cloned rather than migrated, which means they can still access resources in the source forest, they can even access resources after the migration is completed. You can ask users
to switch domain as soon as the new domain is ready.
Therefore, there shouldn’t be a huge downtime/interruption.

How to migrate from existing Database Usermanagement to Active Directory?

Hello experts,
we are running a portal with more than 2000 users. So far our user management is done by the portal´s own identity management with the database as data source.
However for many reasons instead of the database we would like to use an existing company´s Active Directory (=AD) as a data source for identity management. That means that we would like only to use the AD-users and AD-groups in the portal.
All users who are in the portal´s database now you can find also in the existing company´s Active Directory. Luckily the users have the same ID both in the database and in the AD.
We know that the migration form the database to AD is a big issue since many portal objects depend on the existing structures. However because the IDs of users are identical in both systems we hope to finde a way to "override" the existing usermanagement data with the AD data without loosing the existing settings (e.g. KM-Permissions, user profiles etc.).
Generally I am asking you if you have had already experience with changing the user management´s datasource of an already "living" portal (several 1000 users) to Active Directory User Managent.
What problems can occour?
Which modifications need to be done?
Which portal´s objects are affected by the migration?
Is a migration possible at all?
I will appreciate all suggestions, remarks, ideas.
Thanks in advance.
Thomas

Hello experts,
the current permissions in the KM-Objects are based on both groups and users from database.
Because it is not possible to modify the Group´s Display Name in the portal´s database we would also like to use LDAP-Groups in the portal: All users and groups in the portal shall be managed by Active Directory in future.
In the Active Directory it is possible to modify the Display Name of groups. This is a necessary feature because of reorganisations of departments in our company which occur from time to time.
Creating new groups with the new department names is not an option because one has to assign all department members to the new group again. Otherwise one need to asign the new group to the ACLs of all KM objects in question. This is a too big deal.
However, thank you for that hint Michael.
Any other experiences?
I will appreciate any ideas, foreseen problems.
Thomas

Migrating to new Active Directory Domain

Hey people,
I have a OSX Server here at a school which I need to move from an old Active Directory domain to a new one. We are having a restructure of our IT System and 90% of our equipment is PC but have a few macs on site for the specific tasks that we need them to do.
The OSX server was set-up 2yrs ago by some consultant which charged an arm and leg, so its up to me this time round to configure it. It is not a vital part of the IT system so a rebuild is possible, but the quicker it can moved across the better.
So my question is. Is it easier to "modify" the settings on the OSX Server to the new domain? i.e. change field names in Server Admin. or rebuild the server from scratch?
Our configuration is Apple clients authenticate to AD, but grab all their settings and OSX group membership from the OSX server. I have here a guide called "Leveraging Active Directory on OSX" would this be useful if I need to rebuild the server? I am fairly confident that I wont run into too many problems, but things like kerberos settings, etc may confuse me. Any help would be excellent!

Hi,
perform homogeneous system copy if you migrate from one server to other.
find document at service.sap.com/systemcopy
if you just add you local system to domain then look following

Problem migrating account from one active directory domain to another. Using NetBIOS

Hello,
I'm migrating a Lion machine from one domain to another. When I try to join it to abc.example.com it joines it to 123.example.com in the list of domains. 123.example.com is the NetBIOS name of abc.example.com. This configuration does not work.
What is even more strange, is if I go into the Open Directory Utility > Active Directory to set the create mobile account settings, once I apply the settings (or even if I don't apply the settings) when I get back to the list of domains, it show BOTH abc.example.com and 123.example.com as domains I am joined to. If I remove 123.example.com it removes abc.example.com.
I've only seen this problem one other time and this was with a snow leopard machine that was not bound to AD. I upgraded it to Lion and tried to bind it, and had the exact same thing occur.
I'm certain there is a "stuck" setting somewhere that is causing this. I have had successful snow leopard > lion upgrades work, and many lion machines joined to AD so this does work normally. Just not sure whats wrong or really where to look.
The OS is fully patched and updated to the current version.
Any thoughts?

Case 1:
Here you can written pre-update event handler which will check whether minor and major org code changed or not.
If changed then first starts de-provisioning and then start provisioning.
If not changed then do nothing.
This approach will not transfer accounts from one domain to another but it will create fresh accounts and remove accounts from old domain.
Case2:
If you want to transfer accounts from one domain to another in that on pre-update you have to change OU of user on process which automatically move to another domain.
but not sure about exchange it is possible to move to another domain.
hopping that all domains under same forest otherwise same Connector Sever will not work.

Migration on active directory from 2003 to 2008 and SharePoint error Cannot connect to the configuration database.

Hi all,
In advance i`m thankful for your help,
I come across a problem while migrating the Active Directory from Windows Server 2003 to Windows Server 2008 R2,
SharePoint 2010 is getting this error Cannot connect to the configuration database. The same goes for the Administrative page,
Nothing is change in the MySql database, same log in, same server name, i guess it have something to do with the SharePoint Farm,
My question is will reinstalling the SharePoint do the job? Or is there an easy way to get back on my old track?
I`ve try to sync users... no good

Verify that SharePoint is using the correct IP address for the SQL server. To do this, run the ping command on the Windows SharePoint Services server.
Verify that the SharePoint server is obtaining the correct IP address for the SQL server from DNS. To do this, run the
nslookup command from the SharePoint Server.
Make sure that there are no incorrect entries for the SQL server. To do this, examine the Hosts file on the SharePoint server. This file is in the following location:
%systemroot%\system32\drivers\etc\Hosts
On the SharePoint server, look for SQL client aliases. To do this, follow these steps: Click
Start, click Run, and then type cliconfg in the
open box.
Click the Alias tab. By default, there are no SQL client aliases. If you have any aliases for the SQL server, verify that they are correct, or remove them.

Hiya,
I don't think it is necessary to reinstall.
You should just confirm that your basic infrastructure is working.

Active Directory Cross Forest Domain Migration

Dear All,
We are in the process to rebuild new Active Directory infrastructure. Multiple single forest domains in organization which needs to be consolidated/migrated on single Active Directory Domain. For this consolidation, have some queries to be addressed before
going to start consolidation.
What is the best practices and what tool should we use for domain migration/consolidation
Active directory is on Windows 2003, forest and domain level is on Windows 2003, this will support to Windows 2012 R2 forest and domain functional level, will be migrated
directly from windows 2003 to windows 2012?
When move users to new domain, how will they access the other resources on the network. For e.g. Printer, File server, local web base application
After moving some computers to new domain would be possible to access remaining computers on old domain?
How the file server data will be moved? Best practices with NTFS folder permissions and users rights?
Is there any policy to register network printers on new Active Directory domain?
How users would be access web base application on new domain as their FQDN would be define with old domain name? Any option to change old domain FQDN with new domain that would be describe with any URL link?
Kindly give your valuable input to meet the desire result.
Thanks in Advance.

Dear Lucky,
Ya you can Migrate contents from multiple forest domain. Using ADMT (Active Directory Migration Tool)is the best way to migrate AD content. But you can't migrate from Windows Server 2003 to Windows Server 2012 R2, cause in Windwos Server 2012 R2 don't
have the supportebility of Windows Sever 2003.And not only users you can also migrate all others info (i.e. Computer object info, groups info, Exchange mailbox info, security info).You can migrate users face by face, means which peoples are in old domain they
can access old domain and new users are in new domain.For more info please follow the given link:

Migrating frop Active Directory to Open Directory

I have a list of about 25 users currently housed on a windows 2003 small business server. I am moving the email system from exchange to zimbra currently however I would like to completely remove the original server and then only having the new xserve system in place. This means the domain controller will then be the xserve, is there an easy way to migrate the users over(they have nothing on the active directory server but a username and password, nothing fancy). I would also like to create a global samba share for the office, in this share all users would have read / write access. Is there a simple way to accomplish this?

Thanks Andres,
I tried to query the Active directory in the way you said ....but nothing !
ldapsearch
-p 389
-h adhost
-D "cn=Administrator,cn=users,dc=domain,dc=com" \
-w "mypassword"
-b "cn=users.oracle.com"
-s base "objectclass=*"
and in these formats too:
(-b "dc=users.paan.com"
-b "cn=users,dc=paan,dc=com)
I'm really lost, what else could be wrong ?
I'm wondering if there is anything missing from the document i'm following for the Sync.
http://www.oracle.com/technology/obe/obe_as_10g/im/ads_import/import.htm?_template=/ocom/technology/content/print
Conceptually the syncronization seams to be a straighforward process, but in reality I find it quite complicated...........maybe i'm missing some key information.....
Any ideas to suggest ?
thank

Active Directory Migration from 2003 to 2012 Process Flow

We are planning to migrate from Windows Server 2003 AD to Windows server 2012 Server for 6000 Users,
Can any one suggest on Following .
1)What is the Best and Safe Way to do Migration
2) What are the Precautions should take,
3) How much downtime it will take,
4) If migration Failed how we can revert to Earlier
5) How to do Migration Step by Step
Current Environment:
Domain Having One PDC(server 2003 R2) and 8 ADC(Server 2003 R2) in Different Locations
PDC having All FSMO Roles and Global Catalog
Exchange server 2007 was integrated to Active Directory
And some Application are integrated to Active Directory

1) I would recommend you first run a test of the steps in test before you do this in production. Otherwise your production becomes test.
2) By doing in test, you have taken a large amount of the risk out of the upgrade since, in test you should be able to look for any unforseen issues. The easiest way to test is to build a virtual fence from production and clone the DC's and member
servers that you want to test against (This is assuming you are running in a virtual environment). Ensure that you production environment is error free.
http://blogs.dirteam.com/blogs/paulbergson/archive/2009/01/26/troubleshooting-active-directory-issues.aspx
3) There should be no downtime at all, you can just extend the schema and then promote a new 2012 DC (I would recommend R2 if you can).
4) Before you do the schema extension you should take 2 backups on two different DC's. Taking two gives you less of a chance of a problem if one of the backups fails.
5)
Take a backup
Extend the schema
Join the 2012 R2 servers to the domain
Add the ADDS role to the 2012 R2 member servers
Promote the 2012 R2 DC's
Transfer the FSMO roles to the 2012 R2 DC's (Not required but recommended)
If you want to retire the 2003 DC's, then you will need to make sure that any clients pointing to the 2003 DC's for DNS are pointing to other DC's.
If you do retire the 2003 then you can think about updating the DFL and FFL of the domain and forest.

Migrate local OS X profile to Active Directory account

I need to add our MACs to our Active Directory domain.
How do I go about migrating their settings, preferences, and files to the new AD account?
On my test system, when I signed on, it created a new profile and everything had to be reconfigured.
How can I prevent this?

Oh good! Its not just me....
I raised this issue months ago when the version changed to 10.6.x and was told by Apple Lion would fix it...
It didnt, it fact it made it work... the version of Snow Leopard on the mac mini worked perfectly!
I have had mixed results so far... Initially binding to my 2008 mixed mode domain only worked if we specificed a specific Domain Controller and that has worked with a number of machines, our initial fleet of 5 machines for instance
A few weeks ago my lion client was rebooted and on power up it ahd lost its domain binding and nothing would work to get it back on. Im now stuck using a mobile account version of my account...
My new Lion Server just arrived and im following the same procedure and it doesn't work either giving me fairly generic error messages like the one you initially mentioned that leave me confused... In the middle of this project we upraded to 2008 DCs but are still running in 2000 mode...
We are looking at swapping to mac hard ware for our client base and if this issue isnt resolved I cannot move forward; joining a domain is step 1 of a Windows Install usually...
Thanks
Andrew
