It's very impressive if you are able to check out any revision on Trunk
and get the externals *at the correct revision on their Trunks*. Then
you must have some serious automation (or detailed manual process) in
place :)

Personally I find svn:externals to be an often misused feature; they
require a self control I rarely find (or exhibit myself) to be used
well. I tend to remove them wherever I find them.

Your possibility of finding a solution depends a great deal on your SVN
repos and the use of externals. E.g. if your various projects all have
their own TTB-roots and all svn:externals only refer to locations in
other projects (i.e. svn:externals on tags refer to tags in other
projects), then I don't really see any theoretical problem with
conversion. However, svn:external can be used in much more "creative"
ways than that...

Have you looked at https://github.com/hbt/git-svn-migration

It is better to keep your mouth shut and appear stupid than to open it
