GitHub migration tools reimagined

Tue, 17 Mar 2026 08:00:00 +0200

In the last post I wrote about the “State of GitHub migration tools”. I this post I would like to present my humble attempt to unify and improve the developer experience regarding the GitHub migration tools.

State of GitHub migration tools

Mon, 16 Mar 2026 18:00:00 +0200

For some time I am working on migration projects from various platforms to GitHub. What I soon realized is the miserable state of the GitHub migration tools. It is easy to complain when you’re not involved in the development process and don’t know the priorities and decisions. Therefore, I would like to outline the current state of the migration tools and what we maybe can do better.

GitHub CLI Extension Template

Fri, 07 Nov 2025 00:00:00 +0200

Based on the gei project I created a GitHub CLI extension template project for dotnet/C#. This templates comes with a GitHub Actions workflow for build, test and publish the extension out of the box.

gl2gh GitHub CLI Extension

Wed, 29 Oct 2025 00:00:00 +0200

I am working for some time now on a migration project from plattforms like Azure DevOps, Bitbucket and GitLab to GitHub Enterprise. There are official GitHub CLI extensions for the migration from Azure DevOps (ado2gh) and Bitbucket (bbs2gh) to GitHub but unfortunately none for the migration from GitLab to GitHub.

For this case I created based on the GitHub Enterprise Importer (gei) CLI extension the unofficial gl2gh CLI extension. This extension is based on the same code as the other extensions. The code you can find here.

Using Semantic Kernel with multiple services

Mon, 09 Sep 2024 06:30:00 +0200

The builder for the Semantic Kernel (SK) allows to add multiple services to the kernel. I was wondering how the SK knows which service to choose during the runtime. The answer is quite simple.

Project Server Resources

Sat, 15 Jun 2019 09:00:00 +0200

While working with the Project Server I had to search a lot for resources. So I collected them together to have a quick access. I added also Postman collections and environments to have a convenient way to test and work with the Project Server REST and OData API. All the resources you can find in the Project Server Resources repository on GitHub.

Lessons learned from working with Project Server API

Sat, 15 Jun 2019 08:00:00 +0200

Recently I worked on a project involving the Microsoft Project Server 2013. My task was to create a data synchronization using the available Project Server API’s. I never worked with the Project Server before, so this was all new to me. The way to reach the goal was bumpy and sometimes frustrating. But at the end I learned much during this project, so I would like to share it with you.
