A comment on The largest Git repo. Parent comment

How did you go about creating the central repo and how long did it take? A 2Gb at tip svn repo with 100k commits is taking me many days and each odd failure typically has me restart the process after filtering out some obscure part of the tree.

Edit: read in another comment that you dropped the history. Understandable, but can appreciate how that would add to friction (devs having to look through two different histories).

The Windows team developed a tool called "GitTrain" that knew how to:

- migrate the tip of a branch to Git (yes, the 300GB number is the tips of all the interesting branches, not the history)

- keep a Git branch and a SD branch in sync for a while

- be re-run over each of the 400+ branches they care about

But they went through some of the same trial-and-error process that you're describing.
