Choosing Your Migration Strategy: Big Bang, Phased, Greenfield, or Hybrid

Once it’s accepted that a Jira Data Center to Cloud move is coming, the next question tends to show up fast: how should it actually happen? That’s usually where things start to speed up a little too much. Dates get floated. “Big bang” gets mentioned. And suddenly a decision that deserves real thought starts feeling like a race.

This post digs into the most common migration strategies — big bang, phased, hybrid, and even the occasional greenfield reset — and, more importantly, when each one actually makes sense. There isn’t a single right answer, because organizations, teams, and Jira instances aren’t interchangeable.

If you’re in the middle of these conversations right now, or know they’re coming soon, this one is about slowing things down just enough to choose intentionally instead of reactively.

Curious which approach feels most realistic where you are right now — or which one stakeholders are pushing for?

The Road Ahead: Why Data Center Migration to Cloud Matters (and What to Expect)

Doing nothing isn’t an option anymore.

Jira Data Center has a real end date, and ignoring it doesn’t make the work go away — it just pushes the pain further down the road.

This article is about what this moment really means for Jira admins, why “lift and shift” thinking falls apart fast, and how to start planning without overreacting.

If you own Jira, this is a conversation worth having now, not in 2028.
