I'm feeling particularly masochistic today, so I'm going to tackle a project I've been putting off for a while: moving a Rails 1.2.6 app in our subversion repository into github, then updating it to Rails 2.1.
The first part, getting from svn to github, should be relatively painless according to github's "Importing From SVN" guide. It is, as long as you have already created your github repo (I hadn't) and already have git-svn installed (I didn't). So here's the expanded tutorial
2. Be sure you have git-svn installed. I didn't, so here's what I had to do:
sudo port uninstall git-core
sudo port install git-core +svn
I had a bit of trouble with the serf port breaking during build time:
---> Building serf with target all
Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_www_serf/work/serf-0.2.0" && make all " returned error 2
Command output: /opt/local/share/apr-1/build/libtool --silent --mode=compile /usr/bin/gcc-4.0 -O2 -I/opt/local/include -DDARWIN -DSIGPROCMASK_SETS_THREAD_MASK -no-cpp-precomp -I. -I/opt/local/include/apr-1 -I/opt/local/include/apr-1 -c -o buckets/aggregate_buckets.lo buckets/aggregate_buckets.c && touch buckets/aggregate_buckets.lo
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'
make: *** [buckets/aggregate_buckets.lo] Error 1
Error: The following dependencies failed to build: p5-svn-simple subversion-perlbindings serf p5-term-readkey
Error: Status 1 encountered during processing.... so I got all medieval on it, building it manually, then finishing the port install:
> cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_www_serf/work/serf-0.2.0"
> head config.status
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.
It was created by configure, which was
generated by GNU Autoconf 2.61. Invocation command line was

[...more generally successful install noises...]3. Create an authors file
I made mine as authors.txt; it looks kinda like:
jim = Jim Meyer <jim@...>
joe = Joe DiMaggio<joe@...>4. Run the commands from the github guide. My pseudo-values included below:
$ git-svn --authors-file authors.txt clone http://events-svn.example.com/ events_tmp
$ cd events_tmp
$ git remote add origin git@github.com:my_github_username/events.git
$ git push origin master...é voila! It's done! It even (quite cleverly) recognized other authors and properly linked them. Very nice!
