    Migrating SharePoint 2016 and 2019 to Subscription Edition: the scripts

    SharePoint 2016 goes straight to Subscription Edition. There is no hop through 2019, the method is database attach and nothing else, and the order of the service applications is not a preference. The whole sequence in PowerShell, from the inventory you take before touching anything to the crawl you run at the end.

    A Copilot agent manifest is a security boundary. Here is the linter for it.

    Every scoping property in a Microsoft 365 Copilot agent manifest is optional, and in six places omitting one grants the widest scope instead of the narrowest. A JSON Schema validator approves those manifests, because nothing in them is invalid: something optional is missing. So we wrote the check that does catch it. It finds six problems in a manifest that passes every other test.

  3. Development & automation

    We are still measuring engineers by the part that got automated.

    In 2025 DORA threw out its own scoreboard. The low, medium, high and elite tiers that the industry had quoted for a decade were replaced by seven team archetypes across eight measures. That is not a methodology footnote. It is the most used measurement framework in software admitting that the instruments no longer read the thing that decides whether a system survives.

Our first contribution to the official Microsoft 365 samples repository is dated October 2016, five months before there was a 1.0 to build against.

  5. AI & agents

    One agent is an integration. A hundred is a governance problem.

    Agents got production identities before they got a stable way to record what they did. Microsoft Entra Agent ID is generally available, with sponsors and expiry dates. The OpenTelemetry conventions for agent traces are still experimental. That gap is not a detail: it decides what you can responsibly put into production this year, and it turns an AI question into a governance one.

  6. AI & agents

    Agents decide. Code executes. Knowing the line is the job.

    The promise is that agents replace applications. In the systems we build, they do not. An agent is very good at understanding a request, weighing options and choosing a tool. It is the wrong place for a payment, a tax rule or a permission check. This is where the line falls, and why putting it in the wrong place is expensive.
