Database Migration

Hello.
I'm going to migrate an entrie SQL Server to a new box. The original plan
was to backup and restore all DBs on the new server, but due the long time of
the backup I'd like to try other way.
I'm thinking of simply offline->copy->attach .MDF to the new server, but as
the new server has SQL-SP4 and the old one has SQL-SP3 I wanted to know if a
simple attach is risk-free (basically in terms of systables/sysprocedures) or
maybe exist a better way to do it.
What can you advice me?
Thanks
RodrigoBackups should give you much less downtime than you can achieve by
detaching and re-attaching:
1. Database backup on Server A
2. Restore to new Server B
3. Set A to single-user mode
4. Transaction log backup on A
5. Restore transaction log(s) on B
Make sure you read the following article. Particularly the references

There they solve the doubt about moving DBs between SQL versions (answer: no
problem).
The orphan users were been considerated too.
Thanks
