How an engagement runs

  1. 01

    A first conversation

    You describe what is slow, manual or fragile. I ask questions, not for a budget, and say plainly whether it is work I should do.

  2. 02

    Scope in writing

    What changes, what does not, how we will know it worked, and what I need from you: access, a copy of the site, a person who knows the process.

  3. 03

    Build on a copy

    Work happens on a staging copy of your site. You review it there before anything touches production.

  4. 04

    Go-live with a gate

    Releases and migrations follow a rehearsed plan with a tested rollback. Nothing writes to production without approval.

  5. 05

    After go-live

    Fixes, monitoring and upgrades under support and maintenance, if you want them.

Questions I get asked

Will our custom apps break?
The compatibility audit comes first: every custom app is checked against the target version and fixed or replaced before the migration is rehearsed.
How much downtime should we expect?
The migration is rehearsed on a copy of production until it is uneventful; the real run follows that rehearsed plan, with a tested rollback if anything differs.
Can you move the hosting at the same time?
Yes. A migration is often the moment to move to two application servers with a primary and replica database, Docker, CI/CD and Grafana alerting.
