How to migrate all URLs in svn:externals properties across a repository?

Question

We are in the process of moving our SVN repositories from one machine to another one, and with it will come a new domain name for the new repo. The problem is, that within

I had to relocate 12 working copies across 9 users and 4 deployments. It was a simple change, replacing a domain with an IP, i.e. thing.domain.net -> 192.168.0.1

Expecting svn relocate to behave as described (traverse nested externals) I wrote a simple DOS instruction to run at each location:

for /D %G in (*) do ( cd ./%G & svn relocate http://thing.domain.net http://192.168.0.1 & cd ..)

My solution was to edit the repositories themselves (I used Tortoise Repo Browser) to change the location of the externals. Following this change an update to the relocated parent was all that was required to bring everything into line.

It would probably be a good idea to get all the Tortoise users to clear their URL history so they don't inadvertently perform operations using the old URL (it still exists in the DNS lookup):
