SVN copy of one repository to another

Hi everyone,

I want to copy all the source files from one repository to another one,
like this:

repository old
- folder 1
- folder 2

repository new
 - repository old
   - folder 1
   - folder 2
- folder 3
- ...

Can I do this with svn copy? I tried to do this with "svn copy
http://serverIP/old/trunk http://serverIP/new/trunk" and got the
following error:

svn: PROPFIND request failed on '/'
svn: PROPFIND of '/': 405 Method Not Allowed (http://serverIP)

Can anyone help please?

Best regards,
