converting RS2000 reports to 2005

I am trying to convert reports from reporting services 2000 to 2005. I did not open the solution that contained the reports because I wanted to start fresh with a new structure. I added the projects and brought the existing reports in. My question is, I am findingt the only way to convert the reports is to open them in design view and specify that I want to convert them at the prompt. After a little digging, it appeared the only different was the report declaration at the top:

2005:
<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2005/01/reportdefini..."xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">

2003:
<Report
xmlns="http://schemas.microsoft.com/sqlserver/reporting/2003/10/reportdefini..."xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">

Since it is about ten times faster to open the report in xml (code) view, I thought maybe I could just do a search and replace on the two lines above, or at least copy over them, and then save all. I have over 100 reports and it would be pretty time consuming to do a conversion on each. Anyway, my question is is this the only thing I need to do to convert a report or will I screw up my reports doing it this way. I did one and it seemed to work.

Any advice is appreciated.

The RS 2005 Report Server can run RS 2000 RDLs. You can just publish them to the Report Server - they will be auto-upgraded during publishing. Note: when you retrieve it from the report server, you’ll get the original RS 2000 RDL you published to the server.

From that point of view it is not mandatory to upgrade old RDLs to the new schema definition.

BTW: there are a few more changes in the new schema than just the namespace change.
