Doing an entire network migration from one version to another can be difficult. The massive changes that took place between Windows NT4 and Windows 2000 did not come without quite a few errors taking place during most installations.
Doing a migration from Windows NT4 to Active Directory requires that the system administrator use the Active Directory Migration tools. These tools provide all of the resources that are necessary to migrate an older network over to the new operating system. Trying to do this type of migration without the correct migration tools would be an invitation for problems. To minimize these types of problems for customers, Microsoft released the Active Directory Migration Tools (ADMT) . These tools should help you to get through your network migration with minimal problems.
If you are using the ADMT and run into the error code 122, you don't need to take desperate measures, such as backing out of your migration. Microsoft simply recommends that you upgrade or get the newest version of ADMT. This can be done in a matter of a few minutes. All you need to do is open your browser and copy this link - :http://www.microsoft.com/downloads/details.aspx?familyid=6F86937B-533A-466D-A8E8-AFF85AD3D212 into your browser to get the latest version. Download the file and use it instead of the previous version to complete your migration.
It is important to have the most up to date administrative tools when performing a Microsoft Windows network migration. Be sure to check with the Microsoft download pages to make sure that your administrator tools are up to date to avoid these problems.
