Sure. I just had to do this on one of my own repositories so I can
show you what I used. My repository had been created before
Subversion 1.5, and my externals definitions were absolute, like
yours, since that's all one could do at the time.
Now I wanted to switch to relative externals so that my repository
URL was no longer hardcoded into the externals, so that I could be
free to change my repository URL if needed.
"svndumptool.py edit" is for replacing the contents of files, so
that's not applicable.
"svndumptool.py transform-prop" is for transforming versioned
properties, and svn:externals is a versioned property, so that's what
we'll use.
I did something like this:
SVNADMIN="svnadmin"
SVNDUMPTOOL="svndumptool.py"
CREATE="$SVNADMIN create"
LOAD="$SVNADMIN load --ignore-uuid"
DUMP="$SVNADMIN dump"
$DUMP /path/to/old/repo > dump
$SVNDUMPTOOL transform-prop svn:externals \
'^(\S+) http://url/to/old/repo(\S+)' '^\2 \1' \
dump dump-transformed
$CREATE /path/to/new/repo
$LOAD /path/to/new/repo < dump-transformed
Note that you won't be able to check out from the new repository
using Subversion clients earlier than 1.5 because they don't know
about relative externals.
