Question : SQL mdf file attach error

We have purchase document management software and its data files runs on SQL server. First we install software on a Windows server with SQL 2008 enterprise R2 running, than we liked to move it to another server that has SQL 2008 standard version.
In order to move the database mdf file, after installing all the software, you need o attach the mdf file from the old server, which is a 92GB file. Normally there should be no problem and it should attach the mdf file, but this time it gave an error. (see the image).
I did some playing around and saw that when I install SQL 2008 standard R2 version or enterprise R2, it attaches nicely, but when it is standard or enterprise R1, it does not.
Now; we have already purchase 2xcpu license standard SQL version, and I do not want to throw this away and purchase a R2 version.
Is there a way I could attach my 92GB mdf file into my standard SQL? If not; is there a way to make my standard version to R2 version?

SQL Error

Answer : SQL mdf file attach error

The way from SQL 2008 to SQL Server 2008 R2 is a major upgrade (like from 2000 to 2005) thus you cannot use the new file format in the old SQL version.

Even when the software does not need the R2 version the database needs it and that's the problem.

You can try a Bulk copy utility to export the database contents and import it into the older version. This should be database independent. You can also try to link the old server from the R2 version and port all your tables.
