Thanks for sharing! I put together a simplistic script to create a
proof-of-concept: https://gitlab.com/lilypond-issues/lilypond/issues
It's only 1137 issues (now my server is blacklisted for spamming...),
but it has some important features mentioned so far:
* It preserves the issue numbers, and additionally has a link to SF.
* It migrates the current description and all comments.
* It copies the attachments and adds links / previews.
* Status, Type, and Priority are migrated as labels.
* The migrated issue is closed when it was closed on SF.
Obviously I can't post in other person's names, so it has "Originally
reported / posted by" lines at the beginning of every issue and
comment
(unless it had already been migrated from Google Code). Another
shortcoming is that I could not reproduce the threaded structure on
SF,
so all comments are sorted chronologically.
Please all take a look and let me know what you think!
