Migrate issues and discussions from Codeplex to Github

As you probably know Codeplex will be shut down soon. I used Codeplex many years for hosting Camlex project – open source library for creating dynamic CAML queries for Sharepoint by C# lambda expressions. Migration guide available on Codeplex says how to move source code to the Github, but unfortunately it doesn’t mention how to move issues and discussions. In this post I will share my experience of how to migrate issues and discussions from Codeplex to Github.

For migrating issues I used Codeplex-Issues-Importer Python script which worked quite well: it added issues with Codeplex label and closed those issues which were closed on Codeplex. But for discussions it was not so straightforward. First of all in Github there are no such thing as “discussion” as in Codeplex, so I decided to move them to Github issues with “Discussion: [Title]” prefix. In order to perform migration itself I made fork of Codeplex-Issues-Importer and modified it so it started to parse Codeplex discussions instead of issues and then save them into Github as issue. Fork can be found here: https://github.com/sadomovalex/Codeplex-Issues-Importer. Script is not perfect but probably will be enough just for keeping old discussions in migrated project. Result of migration can be checked here: https://github.com/sadomovalex/camlex/issues?page=2&q=is%3Aissue+is%3Aclosed.
