Re: Repository re-organisation / moving files

Thanks the David's advice I tried out dumping the repository, altering
the dumpfile and then loading it into a fresh repository.
Unfortuanately, this seems to fail:

[root@mozart svn]# svnadmin load /svn/hs < /tmp/hs-dumpfile
<<< Started new transaction, based on original revision 1
      * adding path : trunk/data ...svn: File not found: transaction
'1', path 'trunk/data'

Now, I presumed that this was because the trunk directory did not exist
so I attempted to add a new directory in the first revision, adding the
creation of "trunk" to the dumpfile. However, I appear to have been
thwarted as this fails:

[root@mozart svn]# svnadmin load /svn/hs < /tmp/hs-dumpfile
<<< Started new transaction, based on original revision 1
      * adding path : trunk ... done.
      * adding path : trunk/data ... done.
      * adding path : trunk/data/datx.dat ...svn: Checksum mismatch, rep
'3':
    expected: e2d02b210abba3a8582dc95b7abc1909
      actual: 5a7d0fa08b8f68d6c3dc116f892df400

Would it be possible that anyone could give me some pointers here please?

Many thanks for any assistance,

Toby.
