Preparing for a Windows server migration

The following sections list prerequisites for a Windows server migration.

If you use a firewall, see “Disabling firewalls” (page 19) .

Comply with all minimum prerequisites as listed in “Minimum source server prerequisites for all migrations” (page 33).

Windows source server prerequisites

For Windows migrations, verify that the following source server prerequisites are complete:

•If Windows Server 2003 is installed, then verify that the disks are initialized as MBR disks. Insight Control server migration does not support GPT-based disks.

•During migration, the migration agent initiates an operating system reboot on the source physical server. Verify that the operating system is on the first boot order. Insight Control server migration supports migration of source servers that have operating systems installed on the primary drive (Hard Disk 0) and the primary drive loaded first in the boot order.

•Record the drive letter or mount point to disk-partition mapping for dynamic disk partitions before performing the migration. Any simple (non-extended) dynamic disk partitions are converted to basic disk partitions. The mapped drive letters might have to be manually reassigned after migration.

•Before migrating a source server with BitLocker Drive Encryption enabled and drives encrypted using BitLocker, decrypt the drives on the source server and disable BitLocker.

•When a migration is started from a Windows Server 2003 application station to a Windows Server 2008 source server, migrations will be blocked in step 1 of the migration wizard. If the Source Agent was launched from the Windows 2003 application station, the Source Agent will be locked to that specific application station and must be stopped. In order to stop the agent on the Windows 2008 source server, manually run stopHPSMPAgent.cmd tool on the source desktop. The application station must be running Windows Server 2008 (x64) or later to run Windows Server 2008 server migrations.

Source physical server prerequisites

If migrating from a physical source server, verify that the following prerequisites are complete:

•Comply with all minimum prerequisites as listed in “Minimum source server prerequisites for all migrations” (page 33).

•During migration, the migration Agent initiates an operating system reboot on the source server. Verify that the operating system is on the first boot order. If not, then manually change the boot order:

◦For Windows Server 2003, edit the [system drive]\boot.ini file or use thebootcfg.exe tool.

◦For Windows Server 2008 or later, use the bcdedit.exe tool.

Source virtual machine prerequisites

If migrating from a source virtual machine, verify that it complies with all minimum prerequisites as listed in “Minimum source server prerequisites for all migrations” (page 33).

Destination physical server prerequisites

If migrating to a destination physical server, verify that the following prerequisites are complete:
