ADMT Series – 2. Preparing the ADMT Machine

You should install ADMT and SQL onto a member server in the target forest. Use the ADMT service account explained in the previous post to install SQL and ADMT.

ADMT requires a preconfigured instance of SQL Server for its underlying data store, so we’ll go ahead and install SQL 2008 SP1 Express on ADMT.target.local.

Installing SQL Express 2008 SP1

SQL Express download here: http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=25052

1. Choose New Stand-alone installation.

2. Select Database Engine Service.

3. Accept the default named instance.

4. Set an account for the SQL service to run under (use your ADMT Service Account).

5. Set a SQL administrator, choose the user account you plan to run ADMT under- be aware that this user account will need to have local administrative rights in the source domain (this will be discussed further in the series).

Installing ADMT

For this series I will be using ADMT 3.2, which is the supported version for Server 2008 R2. Use ADMT 3.1 for installation on a Server 2008 non-R2 server, or ADMT 3.0 for Server 2003. If you need to migration a Server 2000 Domain, you will need to use ADMT version 3.1 or earlier.

Update Junes 2014 – ADMT 3.2 now supports Windows Server 2012 / 2012 R2.

The requirements are explained in the links below:

ADMT 3.0: http://www.microsoft.com/download/en/details.aspx?id=17488
ADMT 3.1: http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=17918
ADMT 3.2: http://www.microsoft.com/en-gb/download/details.aspx?id=19188

Run the ADMT setup file, and enter the named instance we created earlier.

Here is the ADMT MMC, ready to go.

  1. This is by far the finest guide I’ve seen on ADMT. Thank you.

    Have you got one for cross forest mailbox moves from Exchange 2003 to Exchange 2010 forest?

  2. Hello Tom,

    You have been great with these articles. I have the exact lab set up as per your article. I have installed ADMT 3.2 on a member server 2008R2 and also SQL
    SQL Express 2008 SP1. Both installations went fine, however, I get the error when I open ADMT 3.2 MMC. Error: “Unable to check for failed actions. : DBManager.IManageDB.1 : Unable to retrieve the database file path from the registry. The system cannot find the file specified”
    I can’t figure out what is wrong. Please help……..

    • This is the reason and work around for your error: http://support.microsoft.com/kb/2266373

    • Solution to the issue “error opening ADMT console unable to retrieve the database path from the registry” is
      1. The account with which you are installing ADMT and SQL should be added into local administrators specifically even it is a part of domain admin.
      2. While providing the SQL Server details , use the name of server instead of .(dot) for local server, if your SQL Express is locally installed.

      Following above two points resolved my issue on Windows Server 2008 R2 Standard as well as on Enterprise SP1
