I have duplicate directory structures in two locations that I need to merge together in an svn repository. By "merge" I mean I want all files and folder that are unique to structure b to be moved into structure a. When I try to do this using svn move I get the error

svn: Path 'com' already exists

The folders look like this:

src
 -> com
    -> (many more files and directories)
 -> java
    -> com
       -> (some files and folders, some folders overlap but all files are unique)

src\com is a and src\java\com is b.
