Re: migrating from 5.1 to 5.5 on new hardware

Hi,

in-place upgrade will retain all of your data and settings but sometimes didn't work as expected

so in case you will be forced to migrate your existing data refer to these articles:

VMware KB: Moving the VMwarevCenter Server 4.x/5.x SQL database 

VMware KB: Migrating the vCenter Server database from SQL Express to full SQL Server 

VMware KB: Moving a vCenter Server Oracle database to another host server 

VMware KB: Exporting/importing/restoring Distributed Switch configs using vSphere Web client 

For just upgrade option see:

VMware KB: Upgrading to vCenter Server 5.5 best practices 

VMware KB: Upgrading to vCenter Server 5.5 on a Microsoft Windows platform using the Simple Install method 

Regards,

P.
