Q:

restore SQL 2008 DB R2 to SQL2008 (no r2)

on my developper pc is installed SQL 2008 R2 
on the internal server is installed SQL 2008 R2  (some applications are hosted here)
on the external 3.rd party hosting company uses SQL 2008  (no r2). 
so when I created DB on my developper pc I need to restore on external hosting server which is SQL 2008 (w/o r2).... but I get an build version error... it says SQL2008 r2 has higher build number so I can't restore on the w/o r2 server. 
I thought creating the DB on w/o R2 server and restore on my localhost and make changes and restore back to w/o r2 server, but it says the same error... Build number is changed. 
I thought I can delete r2 version on my developper pc and use SQL 2008 w/o r2, but the issue remains I can't restore the DB from internal server to my developper pc...:(
so in short:
If I want to restore/backup the DB between SQL2008 R2 and SQL2008, how to handle this (I als need the data of database ?  Any property to assign to the DB or whatever? 
Is there a procedure that I can use SQL2008 R2 DB as SQL2008 DB?  
I can't touch the SQL 2008 versions on the server...
please advice? 

A:

You have to export/import using the wizard in SSMS.  Or use some 3rd party tool (eg Red Gate)
There is NO downgrade option using attach/detach or backup/restore.  And no magic setting. 

A:

There is no simple property that you can switch to be able to restore to older versions. 
You might try this, in Management Studio:

Select your source Database 
Select Tasks>Generate Scripts.  
Select 'Script entire database and all database objects', press 'Next' 
Select 'Save to File' and click on the 'Advanced' button 
Select 'Script for Server Version' and select the version you want: 2000/2005/2008
Select 'Type of data to Script' and select Schema/Data/both  
Click 'OK',Next and do it!  
Copy the resulting file to the target machine. 
Log onto your SQL Management Studio and open the copied .sql file... 

It's likely to work if you have a small database.  For a larger one you will run into limitations.
