svndumpfilter and subtrees

I have a repository with multiple projects that used to be branched in
parallel, but now need to be split. How do I accomplish this?

Current tree

zcode/

zcode/trunk/comp1

zcode/trunk/comp2

zcode/branches

zcode/branches/rel_1/comp1

zcode/branches/rel_1/comp2

zcode/branches/rel_2/comp1

zcode/branches/rel_2/comp2

except there are actually 11 components, with 8 staying and 3 migrating
to a new repository, and there are actually about 25 branches. There are
14,000 commits in our repository.

One option (I think) would be to move comp2 to the top using a perl
script against the svn dumpfile so that the tree became

zcode/

zcode/trunk/comp1

zcode/branches

zcode/branches/rel_1/comp1

zcode/branches/rel_2/comp1

ccode/

ccode/trunk

ccode/trunk/comp2

ccode/branches

ccode/branches/rel_1/comp2

ccode/branches/rel_2/comp2

And then filter on zcode vs ccode:

svnadmin create repos/ccode

svnadmin dump repos/zcode | perl -p -e 's-Nodepath:
zcode/(trunk|(branches|tags)/[^/]+)/comp2-Nodepath: ccode/$1/comp2-;' |
svndumpfilter include ccode | svnadmin load repos/ccode

svnadmin create repos/zcode2

svnadmin dump repos/zcode | perl -p -e 's-Nodepath:
zcode/(trunk|(branches|tags)/[^/]+)/comp2-Nodepath: ccode/$1/comp2-;' |
svndumpfilter exclude ccode | svnadmin load repos/zcode2

My concern here is how do directories like /ccode/trunk and
/ccode/branches get created? Can a pre-create them in the new
repository? I don't care that much about preserving revision numbers in
the ccode repo.

I cannot simply clone the repos and then selectively delete as the new
owners of the new repo could potentially recreate the code from the old
repo.

Are there any other options?
