Migrating Sharepoint from Express to full edition on same server.........

I need to move Sharepoint from the Express edition of SQL Server to a full 2008 R2 edition.

I believe I can use the backup/restore functionality to do this but need more in-detail instructions!

Several questions arise:

1. How much needs moving; there are more than 1 databases under the main SHAREPOINT heading?
2. The two editions of SQL server are running on the same virtual windows server (2011SBS) so how do I handle the section that tells users how to access Sharepoint as a simple backup/restore will have duplicate instances?
3. How do I take the express instance offline?

I have little (no) SQL Server experience so need a simple guide to do this please !

Thanks in advance.

Thanks David, could you elucidate a little?
How do start the process and how it handles this?

First, you'll need to close all open sessions and stop the farm in Sharepoint. Then you can migrate the databases to the new server. I wrote an article about how to do that, so give a read on it so you don't miss nothing.
Now, before start the farm in Sharepoint you'll need to update the database connections so it will point to the nem SQL Server. Restart the farm and check if everything is running ok.
