Atlassian Migration to Cloud: A Gliffy Customer’s Story + Key Takeaways for Your Team

With Atlassian Data Center end‑of‑life on the horizon, cloud migration has shifted from a “someday” initiative to an immediate priority, and teams are being asked to move faster than ever—often under pressure, with limited wiggle room. It can feel like a forced transition rather than a strategic choice. 

But as we explored in a recent webinar, cloud migration doesn’t have to be a disruption. When approached thoughtfully, it can become an opportunity to modernize how your team collaborates, documents, and moves work forward.

This blog walks through the key lessons from that webinar, blending real‑world experience, expert guidance, and a customer migration story that shows what’s possible when planning and partnership come together. 

Migrating at Scale: A Gliffy User Story  

A large telecom company with 30,000 Confluence users needed to migrate from Data Center to Cloud.  

This meant...  

• A high volume of content, including Gliffy diagrams. 
• A tight window of time for a migration that must take place outside business hours. 

The combination of these two requirements meant that a lot of content needed to be moved quickly, and at first, that wasn’t possible. 

To help the customer migrate within the required time window, Gliffy’s engineering team worked closely with Atlassian to optimize a migration path. 

In the end, the migration only took four hours—80% faster than before. Then, these improvements were released to all customers, making migration faster for all.

Make Migration More Than “Moving Servers”  

With the 2029 deadline approaching quickly, many teams are feeling forced into this moment, but when you take a step back, you can start to see the benefits of the situation.  

Instead of viewing it as a straightforward transfer, think of it like moving house. Yes, you’re bringing your belongings with you—but you’re also entering a new space with different possibilities. It’s a chance to rethink how you live, work, and organize what you keep. 

Migration creates space to: 

• Remove outdated or unused content 
• Improve structure and organization 
• Adopt new capabilities that simply weren’t possible before 

When teams plan only for continuity, they miss the chance for improvement. You have an opportunity now to fix some of the problems that might be inherent to your current design and systems. 

As part of this process, you need someone who understands the needs of the business to be involved: someone who understands where the organization is headed, what challenges it faces, and what outcomes matter most. Are teams trying to collaborate more effectively across regions? Improve visibility into work? Accelerate delivery? 

Then, it’s important to also measure the results. Whether that’s speed of delivery or another metric that shows how well your team is performing, you can ensure that you’re getting positive improvements as you make these changes.  

Already In Atlassian Cloud? It’s Not Too Late to Optimize 

If you’ve already migrated to Cloud, or your migration is currently in progress, you haven’t missed your chance to improve your workspace.  

Even after migration, teams can: 

• Declutter old and outdated spaces 
• Restructure information architecture 
• Re-engage users through training and communication 
• Take advantage of Cloud-only features that may not yet be in use 

Migration is just the beginning. The real value comes from how well teams evolve their ways of working once they’ve landed. 

Key Takeaways for Your Atlassian Migration to Cloud 

Security, Compliance, and Data Residency Considerations 

For industries like finance and government, security and data residency are non‑negotiable. 

Teams should evaluate: 

• Atlassian’s Trust Center documentation 
• Each Marketplace app’s security and privacy details 
• Certifications like Cloud Fortified and Runs on Atlassian 

Gliffy aligns closely with Atlassian’s standards and even goes above and beyond with achievements like SOC 2 compliance and ISO 42001 certification, ensuring organizations can modernize without compromising on compliance.

Talking to Business Leaders About Cloud 

Earlier, we discussed the importance of working through your migration with someone who understands the needs of the business, including its direction and current challenges.  

When translating technical benefits into business value, frame the conversation around:  

• Productivity gains 
• Faster decision‑making 
• Better collaboration 
• Time saved per employee 

You can even use visuals and AI-driven diagrams to simplify explanations.  

You Don’t Have to Do It Alone 

As you plan your migration, there are several resources at your disposal to make sure the process is as smooth as possible, including: 

• Gliffy support and customer portal 
• Solution partners like Eficode 
• Atlassian’s FastShift program 
• Migration checkpoints and best practices 

Don’t hesitate to ask questions and seek guidance early to avoid complications later. 

Final Thoughts: From Mandated Migration to Competitive Advantage 

Cloud migration is as much about people as it is about platforms. 

When IT, business owners, and end users work together, supported by the right partners and tools, migration becomes a catalyst for better collaboration, clearer communication, and more efficient teams. 

And the good news? You don’t have to navigate it alone. From Gliffy’s support team to experienced solution partners like Eficode, help is available at every stage. 

Cloud migration may be mandatory, but turning it into a competitive advantage is a choice.
