This situation is not that easy, it depends from what Database you are using (what RDBMS). If you are talking about MySql, this can be done that way, but before copying the database, you need to stop de MySql service, so the data is consistent, and then you can do your backup. In the other server, the MySql must be the same version, and the MySql service must be stopped too. After restoring your previous backup, and starting the MySql service, you will see your data in the other server.
If you are using a Oracle backup, you will need to do a Full Backup, using the backup tool provided with de Oracle software (export command).
If you are changing from one RDBMS to another, then you need to do a dump of the data, in SQL Standard format, so you can restore or import to another RDBMS with minimal or nothing troubles.
Talking about the hardware, this is not relevant to the database server, and Itanium is a good processor.
I hope this helps you.
