I am assuming that you are migrating from Exchange 2003 to Exchange 2007.
Once you setup Exchange 2007, during the co-existence phase, you could just use the move mailbox command to move mailboxes from different exchange 2003 databases to a single database on 2007.

Hi there,

there are actually no extra tools required to migrate frmo Exchange 2003 to Exchange 2007.
If you transition from one version to another, you actually move mailboxes from one server to another.

Here is a step-by-step guide that might help you:

Tks for prompt answer.
The three sbs 2003 servers are no more in production. Private databases have been saved as single files.
How to concatenate those three databases in one knowing that files are not compatible with exchange 2007.

If you cannot restore the database to an exchange server you can use 3rd-party tools such as Ontrack PowerControls to read the flat-files (.edb) and export mails to PST's. Afterwards you can import them into your Exchange 2007 Mailboxes.
