Cloud Migration Deep Dive - Fully Released!

25th March 2026 (updated)

Atlassian Cloud Migrations can be really tough.  With the recent announcement of the Data Center End of Life, the clock is ticking for complex Atlassian estates across the market.  As much as the standard xCMA-based approach can work well for smaller or simpler instances, the Data Center landscape contains many more complicated, large instances than have been migrated in the past.  At these scales, the cracks in the naive approach begin to show.

At Echidna Solutions, based on our individual 10+ year histories within the Atlassian ecosystem, we believe there is a better way.  As proven with our Rightmove Case Study, the Echidna approach can reduce costs and timelines, whilst simultaneously providing a better end result than the traditional lift-and-shift.

In this 5-part series written by Jamie Sawyer, Director at Echidna Solutions, and 15-year veteran of the Atlassian ecosystem, we will make sure you don't only get told the approach, but have enough context to truly understand it.

• In Part 1, we get started with the early days of Atlassian, their first forays into the world of SaaS, and how Plugin and App architecture truly shaped (and, perhaps, complicated) everything that came after.

• In Part 2, we explore how Data Center changed the story for Atlassian's licensing model, its differences and similarities to the original "Server" architecture, and how its release ushered in the Era of Divergence for the Atlassian product lines.

• In Part 3, we take a deep technical dive into the tooling that shaped Cloud Migrations over time, providing insight into how each approach excel in different areas, and more importantly, where they fall down.

• In Part 4, we dive into the detail of the Echidna Approach, and walk through every step of the process - giving you the full why and how of our approach to migrations.

• In the Final Part, we give you some real life tales from the frontlines of Cloud migrations over the years, and explore the lessons that we can learn from them.

A consolidated PDF - The Complete Guide to Cloud Migrations - will be releasing soon, with bonus exclusive content, details of which will be announced shortly!  Fill in our form to express interest in getting early access to the document for easier reading, or to share with your colleagues.
