Move Your Atlassian Stack to Cloud – Without Losing What Makes It Yours
The end of Atlassian Data Center doesn’t have to mean the end of your custom solutions. Whether it’s missing apps, unsupported scripts, or non-compatible automations – our technical experts can recreate, modernize, and migrate everything you rely on.
We don’t just move you to Cloud – we make sure your unique workflows stay intact.
Why Work With Seibert’s Dev Teams?
Forge Expertise with Cloud-Native Tech
Forge is the future of Atlassian app development – and we know it inside out. Combined with modern Cloud technologies we deliver custom apps that are built to last in Atlassian Cloud.Hands-On Technical Migration
Your workflows, scripts, and automations don’t just move – we reimplement and optimize them using Forge and Cloud APIs, ensuring they remain functional, scalable, and easy to maintain.Custom Builds Beyond Off-the-Shelf
From one-to-one replacements to entirely new features, we design and code tailored solutions so your teams have exactly what they need – nothing more, nothing less.Cloud-Native Mindset
Every build is designed to be secure, scalable, and future-proof within Atlassian’s evolving Cloud ecosystem. Your solutions grow with your business, not against it.

Missing Apps? We’ll Rebuild Them
Just because your favorite Data Center apps don’t exist in Cloud doesn’t mean you need to change how you work. We rebuild missing apps from the ground up, preserving the functionality your teams rely on. The result: seamless workflows, no lost productivity, and apps tailored exactly to your Cloud environment.
Cloud Security, Your Way
Some Cloud apps fall short when it comes to security, compliance, or control. That’s where we step in. We develop custom-secure alternatives that meet your standards for data residency, permissions, and governance. You stay in full control, without having to compromise on Cloud.
Script & Automation Migration
Scripts and automations built for Data Center rarely translate directly to Cloud. We analyze, refactor, and reimplement them using modern Cloud frameworks and APIs. Your business logic stays intact, while becoming more reliable, scalable, and easier to maintain in the long run.

What Makes Us Different
Frequently Asked Questions
What is the Atlassian DC EOL timeline developers should plan for?
What is the Atlassian DC EOL timeline developers should plan for?
The wind-down starts on March 30, 2026. Full end of life is March 28, 2029 (23:59 PST). Engineering demand will spike well before 2029 – make sure to secure capacity early.
Can you rebuild DC-only Marketplace apps for Cloud?
Can you rebuild DC-only Marketplace apps for Cloud?
Yes. We implement functional equivalents as Cloud apps using Forge, with Cloud UX adjustments and migration utilities where feasible.
How do you migrate DC scripts and automations?
How do you migrate DC scripts and automations?
We catalog your scripts, map them to Cloud APIs or automations, and refactor where necessary. When logic is too complex, we re-implement it in a custom Cloud app.
What about security and compliance for Cloud apps?
What about security and compliance for Cloud apps?
We apply enterprise security practices – least privilege access, secrets management, secure storage, and audit logging – while aligning with your compliance standards.
Do you support phased cutovers or zero-downtime migrations?
Do you support phased cutovers or zero-downtime migrations?
Yes. We design phased rollouts with feature flags, backfills, and coexistence strategies to minimize disruption.
How do you handle data migration for custom apps?
How do you handle data migration for custom apps?
We design and test schema transformations, build migration utilities, and run rehearsals in staging with clear acceptance criteria and rollback plans.
Can you train our developers on Forge and Cloud APIs?
Can you train our developers on Forge and Cloud APIs?
Yes, through our colleagues at Seibert Products: practical developer workshops on app scaffolding, permissions, UI kits, testing, CI/CD, and operational best practices.
Is Bitbucket Data Center included in the EOL?
Is Bitbucket Data Center included in the EOL?
No. Bitbucket DC moves to a Hybrid License model. We still support Cloud integrations and custom workflows for it.
