Install or Upgrade to MDT for LTI Deployments

To perform LTI deployments, you must have at least one instance of MDT 2010 running in your environment. If your existing environment has:

· No computers currently running MDT or a previous version of MDT, then install one or more new instances of MDT as described in Installing a New Instance of MDT

· One or more computers running a previous version of MDT, then upgrade those instances to MDT as described in Upgrading to MDT. After the upgrade process is complete:

· Existing MDT 2008 media deployment points are upgraded to media items in MDT. However, the items you select in the media deployment point, such as applications, task sequences, driver groups, or package groups, are not preserved. Before updating the media, create folders for each type of item that are not migrated and a selection profile that selects each of those folders. Then, configure the media to use the selection profile and update the media.

Note If you do not create the folders and selection profile, the media item will use the Everything selection profile, which includes all items and may not be the desired configuration.

· Existing MDT 2008 network deployment points are upgraded to linked deployment shares in MDT. However, some of the items selected in the network deployment point are not preserved, such as applications, task sequences, or package groups.

However, driver groups are migrated if they are configured to a value other than All Drivers. A selection profile named Windows PE Drivers for NETWORK is created for the driver group selected for Windows PE device drivers and the linked deployment share is configured to use the migrated selection profile.

Before updating the linked deployment share, create folders for each type of item not migrated and a selection profile that selects each of those folders. Configure the linked deployment share to use the selection profile, then replicate the linked deployment share.

Note If you do not create the folders and selection profile, the linked deployment share will use the Everything selection profile, which includes all items and may not be the desired configuration.

· Existing MDT 2008 LAB deployment points are upgraded to deployment shares in MDT. However, some of the items selected in the LAB deployment point are not preserved, such as applications, task sequences, or package groups.

However, driver groups are migrated if they are configured to a value other than All Drivers. A selection profile named Windows PE Drivers for LAB is created for the driver group selected for Windows PE device drivers and the deployment share is configured to use the migrated selection profile.

· Boot image settings for MDT 2008 media deployment points are not preserved. Instead, the boot image settings from the parent deployment share are copied to the media. You may need to modify the boot image settings to reflect the original boot image settings.

· Task sequences are recreated using the LTI task sequence templates in MDT. Custom task sequence steps in task sequences created in BDD 2007 are moved to the Custom Tasks groups in the upgraded task sequence. After the upgrade, you may need to move the custom task sequence steps back into their correct sequence in the task sequence.

· Task sequences will not include the Apply Local GPO Package task sequence step. If you want to apply GPO packs using this feature, you must manually add the Apply Local GPO Package task sequence step to any task sequences that existed prior to the upgrade. For more information on GPO packs, see Applying Group Policy Object Packs.
