Specifications

Table 4‑5. restore Command Variables (Continued)
Variable Description
TargetAlias The alias for the new database.
LogsLocation The directory where log files for the new database are
stored.
NumBuffers The number of buffers used for the restore operation. If
you do not specify the number, by default the system uses
two buffers.
BufferSize The size, in pages, that each buffer uses to perform the
restore operation. The size of each buffer used by this
operation is based on the value of the backbufsz DB2
Database Manager configuration parameter.
ParallelNum The number of tablespaces that the system can read in
parallel during a restore operation.
Back Up VirtualCenter or vCenter Server Configuration with the Data Migration
Tool
The data migration tool allows you to back up VirtualCenter or vCenter Server configuration data such as
port settings, SSL certificates, and licensing information. The data migration tool can restore these settings
when you upgrade to vCenter Server on a new 64-bit host machine.
If your database is a SQL Server Express database that is local to the VirtualCenter or vCenter Server
machine, the data migration tool will back up the database and restore it to the destination machine.
If VMware vCenter Orchestrator is installed on the same machine as VirtualCenter or vCenter Server, the
data migration tool will back up the vCenter Orchestrator configuration and restore it to the destination
machine. The data migration tool does not back up and restore the vCenter Orchestrator database. See
Installing and Configuring VMware vCenter Orchestrator for information about upgrading vCenter
Orchestrator using the data migration tool.
If VMware vCenter Update Manager is installed on the same machine as VirtualCenter or vCenter Server,
the data migration tool will back up the vCenter Update Manager configuration and restore it to the
destination machine. If vCenter Update Manager uses a SQL Server Express database that is local to the
source machine, the data migration tool will back up the database and restore it to the destination machine.
The data migration tool does not back up and restore patch binaries. See Installing and Administering VMware
vSphere Update Manager for information about upgrading vCenter Update Manager with the data migration
tool.
Prerequisites
n
Verify that a supported version of VirtualCenter or vCenter Server is installed on the source machine:
n
VirtualCenter 2.5 Update 6 or later.
n
vCenter Server 4.0.x and its update releases.
NOTE vCenter Server 4.1.x is not supported for the data migration tool. vCenter Server 4.1.x
requires a 64-bit host machine. Because vCenter Server 4.1.x cannot be installed on 32-bit host
machines, there is no case for migration from a 32-bit machine to a 64-bit machine.
n
Stop the VMware VirtualCenter Server service before you back up the configuration.
n
If the \datamigration\data\ folder exists from a previous backup attempt, backup cannot proceed.
Remove or rename this folder before you back up the vCenter Server configuration.
