Active Directory Migration and Standardization

For over 10 years FirstAttribute has successfully been involved in Active Directory migration projects. A successful Active Directory migration is characterized by the mandate's sensation that the migration was executed "softly". Employees continue working throughout the whole process and the maximum interruption is a reboot of their PCs.

The access to any and all resources is also constantly possible during the Active Directory migration. The Active Directory attribute sIDHistory should be known by anyone who has dealt with the subject of migration. The SIDHistory is responsible for the access of the migrated accounts to not yet migrated resources.

An Active Directory migration is usually done using migration tools, so that as much information from the existing Active Directory domain as possible can be transferred to the new domain. Sometimes it is decided to create a whole new Active Directory where all of the objects are new. This approach is usually only usable in small surroundings.

Tip: Components to consider while performing an Active Directory migration:

• Infrastructure services like DNS, DHCP, WINS, time synchronization
• Active Directory replication and trusts
• Group directives and login-scripts
• User and group- objects
• Computer objects
• Resources like file, print, main and application server

TIP!: A successful Active Directory migration contains the following steps:

• Analysis of the existing Active Directory domain(s)
• Execution of optimization in the existing environment, especially if they are necessary for the Active Directory migration
• Hold workshops for the planning of the new Active Directory environment
• Definition of the migration and the implementation of the tools to be used
• Preparation of a rollout plan including a definition of a test and pilot migration
• Development of the target environment, in case it does not yet exist
• Development and implementation of the migration tool
• Execution of the test migration using test-systems
• Execution of the pilot migration using productive systems
• Analysis of the pilot-migration results
• Execution of necessary adaptions based upon the analysis of the pilot migration
• Execution of the rollout
• Removal of the migrationtool and, if necessary, of the source environment
