You must back up a VirtualCenter 2.x system to ensure that you can restore your previous configuration of VirtualCenter if the vCenter Server upgrade does not complete successfully.

If you begin the upgrade to vCenter Server, and you did not back up your VirtualCenterĀ 2.x database and SSL certificates, you cannot restore your previous VirtualCenter configuration. You cannot roll back your database to the previous database schema. The only way to recover from an unsuccessful upgrade is to use your backed up database and SSL certificates.

1

Make a full backup of the VirtualCenter 2.x database.

See your database documentation.

2

Back up the VirtualCenter 2.x SSL certificates.

a

Copy the SSL certificate folder under %ALLUSERSPROFILE%\Application Data\VMware\VMware VirtualCenter or %ALLUSERSPROFILE%\VMware\VMware VirtualCenter\.

b

Paste it at the backup location.

3

Take notes on the existing VirtualCenter installation regarding the selections, settings, and information used. For example, note any nondefault settings, such as the IP address, the database DSN, user name, password, and assigned ports.

4

Create a backup copy of vpxd.cfg.

Continue with the upgrade to vCenter Server.
