Domain Controller Cross Forest migration Part 1

In this series of articles I will demonstrate the Cross forest migration for Microsoft Windows Active directory 2012 R2.

Before starting any step, I will have to do a revision for the current environment and check what is there, what can be migrated and what can not be.

Revisions:

1. Check if the environment is using an old cryptographic algorithms that’s not supported during the migration .e.g. (SHA-1 1024bit Certification authorities).
2. Notice that Group Policy user profile folder redirection might have a bug from SCCM. To fix this the SCCM needs to be checked for one option needs to be disabled
3. Under the SCCM Configuration manager,

– Select Administration

– Select Client Settings

– Pull up PROPERTIES of Default Client Settings configuration and click on Compliance Settings

– Enable User Data and Profiles mentioned above is the setting which drives the control of Folder Redirection and Remote User Profiles.

The above configuration by Default is set to NO. Once enabled (set to YES), it passes the control of Folder Redirection, Offline Files, and Remote User Profiles to WMI and stores this configuration under the registry path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\UserState\UserStateTechnologies\ConfigurationControls

TCP/IP crashes and errors: Hotfix released to correct a crash in TCP/IP.
