Here is a plan for this lesson.
First we'll talk about Active Directory migration tool and what kind of tasks it supports for completing
a domain migration.
Next we'll talk about pre migration steps which you must complete to prepare the source and target domains.
Then we'll talk about inter forest restructure and with Ada empty an entire forest restructuring involves
five steps to be performed namely the steps are create and a restructuring plan.
Prepare and source and target domains migrate and accounts migrate and resources and finalize in migration.
And finally we'll talk about seed history attribute.
So let's start as part of deploying aid in the.
You might choose to restructure your environment for the following reasons you might want to restructure
it to optimize the legal aid it is structure as in some organizations the business might have changed
significantly since ATF was first deployed.
As a result the ADT is the main or forest structure might no longer meet the business requirements.
Another reason you might want to assist in completing a business merger acquisition or divestiture restructuring
involves migrating resources between 80 days domains in either the same forest or in different forests
a radius has no option to detach a domain from one forest and then attach it to another forest.
You're going to rename and rearrange demands within a forest under some circumstances.
But there is no way to easily merge demands within or between forests.
The only option to restructure in a domain in this way is to move all the accounts and resources from
one domain to another domain.
You can use the active directory migration tool to move User Group and computer accounts from one domain
to another and to migrate server resources.
If managed carefully the migration can be completed without disrupting users access to the resources
that they need to do their work e.g. empty provides both a gooey and a scripting interface and it supports
the following tasks for completing a domain migration.
It supports user account migration group account migration computer servers account migration trust
migration Exchange Server director a migration security translation on migrated computer accounts report
and features for viewing their migrations results and functionality to undo the last migration and to
retrace the last migration.
Please consider this re migration steps before performing a migration.
You must complete several tasks to prepare the resource and target domains.
These tasks include four domain member computers that predate Windows Vista Service Pack 1 or Windows
Server 2008 are 2.
You have to configure a registry key on the target 80 days.
Domain Controller to allow group to grow for algorithms that are compatible with Microsoft Windows and
server for operating system.
You have to also enable firewall rules on source and target ADT as the main controllers to allow file
and printer sharing.
Also you have to prepare the source and target edit is domains to manage how users groups and user profiles
will be handled.
Another task is to create a rollback plan and to establish the task relationships that are required
for the migration.
You have to configure a source and target edit as demands to enable seed history migration and you have
to specify service accounts for the migration.
And last but not least you have to perform a task migration and fix and reported errors.
Now some words about inter forest restructure and was Ada empty an entire forest restructuring involves
moving resources from source domains that are in different forests than the Tajik domain to use Ada
M2 to perform an inter forest restructuring you have to do the following.
First you have to create a restructuring plan an adequate plan is critical to the success of the restructuring
process.
Complete the following steps to create your restructuring plan.
A determined the account migration process be assigned object locations and location map and see develop
a test plan.
Then create a rollback plan and create a communication plan.
After agreed in a restructure and plan you have to prepare a source and tortured demands for the restructure
and process by performing the following tasks.
Ensure that 1 20 a bit encryption is on all domain controllers Windows Server 2000 service box 3 and
newer versions natively support 1 28 bit encryption for older operation operating systems.
You must download and install a separate and groups and back within this step you have to also establish
required trusts you must configure at least a one way trust between the source and target domains.
After doing so you have to establish migration accounts as a empty users migration accounts to migrate
objects between source and target domains.
Ensure that these accounts have permissions to move and modify objects on the source and target domains.
After this step please determine whether Ada M2 will handle seat history automatically or if you must
configure the target and service domains manually then ensure proper configuration of the target domain
or use structure ensure that all you configure the proper administrative rights and delegated administration
in the target domain.
After that install Ada empty in the larger domain and enable password migration then perform a test
migration with a small test account group and switch to step 3 which is my great account.
You have to perform the following to migrate accounts.
You have to have transition service accounts then migrate global groups and migrate accounts.
Consider migrating user and computer records and badges to monitor the migrations process.
If you are migrating local profiles as part of the process migrate the affected computers first and
then the associated user accounts.
After this switch to step 4 which is my great resources you have to migrate the remaining resources
in the domain by performance the following steps.
First migrate workstations and member servers then migrate domain local groups and after that migrate
domain controllers and finally move on to the final step which is finalized on migration.
You have to finalize the migration and perform cleanup by performance the following steps.
First transfer administration processes to the target domain.
Second ensure that at least two operable domain controllers exist in the target domain.
Backups as domain controllers.
And finally decommission the source domain.
Now some words about seed history attribute during the migration you might have moved use around group
accounts to the new domain but the resources that the users need to access might still be in the old
domain when you migrate a user account.
Edit Here's a science ID and you seed because the resource in the source domain grants access based
on the user receipt from the source domain.
The user can not to use the new suit to access their resources until the resources moved to the new
domain to address this situation.
You can configure a duty to migrate they see it from the source domain and then store the seed in an
attribute called SEED history.
When the seed history attribute is populated the user as previous seed is used to grant access to resources
in the source domain search history increases the size of users access tokens after migrating users
to the new domain.
The access control lists in your in should be examined and you should also migrate the ACLU.
After our migration is completed and the original domain has been removed you should clean up your users
seat.
Here's to attribute.
You can best accomplish this task by using the get seed history and remove seed history.
Windows power shall command laps.
You should carefully plan and exactly use activities because removing said history before the environment
is properly prepared could cause business interruptions.
