When you upgrade to vCenter Server and use an existing supported database, the Database Upgrade wizard runs after you click Install in the vCenter Server installer. The Database Upgrade wizard upgrades the existing database schema to make it compatible with vCenter Server 4.0.

For upgrades from VirtualCenter 2.5, the Database Upgrade wizard runs in the background. This procedure is for upgrades from VirtualCenter 2.0.x.

1

In the Database Upgrade wizard Welcome page, click Next.

2

On the Upgrade Information screen, select an option for performance data.

Select Keep all performance data and click Next to preserve performance data from your existing database.

Select Discard all performance data and click Next to discard performance data from your existing database.

Select Keep performance data recorded during past 12 months and click Next to preserve only the most recent performance data from your existing database.

The table for performance data can be large. If you do not keep the table, you cannot view historical performance statistics for the time when the database was maintained in VirtualCenter 2.x.

3

Review your selections, click Next, and click Start.

Your database is now compatible with vCenter Server 4.0. It is no longer compatible with VirtualCenter 2.x. The vCenter Server installer begins installing vCenter Server 4.0.

Click Finish to complete the upgrade to vCenter Server.

VirtualCenter 2.x is upgraded to vCenter Server 4.0.
