When you upgrade to vCenter Server, you can migrate vCenter Server to a new machine. One reason for doing this is to move from a 32-bit machine to a 64-bit machine.

You can also use the data migration tool to migrate a SQL Server Express database installed by the vCenter Server installer on the same machine as vCenter Server. If you use a different database installed on the vCenter Server machine, you must back up and move the database manually to the new machine. If the database is installed on a different machine from vCenter Server, you can leave the database in place and create a new DSN on the destination machine to connect to it.

The VirtualCenter or vCenter Server configuration settings that you can migrate with the tool include:

LDAP data

Port settings for the HTTP, HTTPS, heartbeat, Web services, LDAP, and LDAP SSL ports

Certificates stored in the SSL folder

License

Database data for a bundled SQL Server Express database only

If VMware vCenter Update Manager or vCenter Orchestrator is installed on the same machine as vCenter Server, you can use the data migration tool to migrate configuration data for these products. You can also use the tool to migrate the vCenter Update Manager database if it is a SQL Server Express database installed on the same machine as vCenter Update Manager and vCenter Server. You cannot use the data migration tool to migrate the vCenter Orchestrator database. See the documentation for vCenter Update Manager and vCenter Orchestrator for more information on upgrading these products.

If you are using a remote database, either remove any ESX Server 2.x hosts from the VirtualCenter or vCenter Server inventory or upgrade these hosts. If you are not using a remote database, you do not need to remove ESX Server 2.x hosts from the VirtualCenter or vCenter Server inventory or upgrade them, however they will not be connected to the vCenter Server after the upgrade.

Stop the VMware VirtualCenter Server service before performing this upgrade.

1

Before you upgrade vCenter Server, back up the vCenter Server database. If you are migrating vCenter Server to a new machine, you have several options for moving the database.

2

Use the data migration tool 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 machine.

3

The vCenter Server system must have a 64-bit DSN. This requirement applies to all supported databases. By default, any DSN created on a 64-bit system is 64 bit.

4

Use the data migration tool to start the vCenter Server installer and restore the vCenter Server configuration to the destination machine.

5

When you migrate the vCenter Server configuration to a destination machine that does not have the same name as the source machine, you must update the plug-ins to use the new machine name. Plug-ins registered to the vCenter Server system cannot access the destination vCenter Server machine until this update is complete.

6

If the license server was installed with vCenter Server on the source machine, the data migration tool cannot migrate the license server to the destination machine. You must migrate the license configuration manually.
