Thanks. I'm looking at doing it myself, using a combination of the 
instructions at

https://savannah.gnu.org/maintenance/UsingGit/

and

https://epicserve-docs.readthedocs.io/en/latest/git/svn_to_git.html

git svn is going to take a long time to run as it has to connect to the 
svn repository for every commit, and there are thousands of them.  
Hopefully I can do it right the first time and don't have to waste a lot 
of time on trial and error (although I've just noticed the help page on 
Savannah has some advice about getting a local copy of the SVN repo 
first).

https://git-scm.com/docs/git-svn recommends against the --no-metadata 
option.

Although https://savannah.gnu.org/maintenance/UsingGit/ says that 
git-svnimport can be used for conversions, I don't have a git-svnimport 
command on my system.  (I have git 1.8.4 installed.)  "git svn" should 
be sufficient.

I think I need to do an author map file. Fortunately there are not that 
many committers. It would be helpful it people could have a look through 
the following and check for mistakes:

adl = Alexandre Duret-Lutz <address@hidden>
adrian = Adrian Aichner <address@hidden>
akim = Akim Demaille <address@hidden>
arnold = Arnold D. Robbins <address@hidden>
dirt = Alper Ersoy <address@hidden>
dprice = Derek Price <address@hidden>
eliz = Eli Zaretskii <address@hidden>
feloy = Philippe Martin <address@hidden>
gavin = Gavin Smith <address@hidden>
gray = Sergey Poznyakoff <address@hidden>
httpd = Karl Berry <address@hidden>
juan_g = Juan Manuel Guerrero <address@hidden>
karl = Karl Berry <address@hidden>
kasal = Stepan Kasal <address@hidden>
mthl = Mathieu Lirzin <address@hidden>
olegkat = Oleg Katsitadze <address@hidden>
pertusus = Patrice Dumas <address@hidden>
reiter = Peter Moulder <address@hidden>
trueroad = Masamichi Hosoda <address@hidden>
uid65818 = Karl Berry <address@hidden>
wl = Werner Lemberg <address@hidden>


For several of the names I had to look through the log history to find 
out who they were. The names don't seem to match up exactly to Savannah 
usernames.  For example "adrian" is not apparently the same person as 
https://savannah.gnu.org/users/adrian - he made two revisions, SVN 
revisions 28 and 29 and the diff shows it is someone else.

uid65818 only has one commit and it appears to be a relic of an earlier 
change in version control system or repository hosting (svn revision 
1209).  Likewise httpd only has commit 10.  I've put Karl for both as 
it was probably him who was doing it at the time.

I identified "reiter" from the ChangeLog for texi2html.

There is an existing git repository on Savannah which is out of date. I 
haven't worked out yet how it can be replaced or updated.
