THE MIGRATION JOURNEY WITH AN EXPERIENCED PARTNER

ByteSource Cloud Migration Service

We accompany you through the migration project with a standardized process plan and tools developed by Atlassian, which supports you organizationally and technically in all phases.

Phase 1: Analysis & Assessment

Goal: Decide whether a cloud migration makes sense — technically, economically, and strategically.

In this phase, we work together with the customer to analyze the current Atlassian environment (Jira, Confluence, Bitbucket, etc.).

We assess:

Instance size, number of users, and group structure
Product versions and configurations
Marketplace apps and custom developments in use
Interfaces to third-party systems
Performance, maintenance efforts, and system load
License status and ongoing costs

Based on this analysis, we compare the options between Atlassian Cloud and Data Center and advise on whether a cloud migration is a viable choice.

We also address data protection and compliance topics — especially for customers with strict requirements (e.g., GDPR, ISO 27001).

Outcome: If a migration is recommended — setting the first strategic direction.

Phase 2: Planning

Goal: Develop a customized migration plan designed to minimize risks.

In this phase, together with the customer, we define:

The appropriate migration strategy (big bang, phased migration, or hybrid operation)
The ideal timing for the migration (e.g., aligned with sprint cycles, vacation periods, or release plans)
The most suitable Atlassian Cloud products and plans
Potential challenges related to data migration and app compatibility
Roles and responsibilities of all stakeholders (project management, admins, key users)
Contingency plans and testing concepts

Outcome: A clear, actionable migration plan — including timeline, task allocation, and risk mitigation measures.

Phase 3: Preparation

Goal: Establish all technical and organizational prerequisites for the migration.

This phase is critical to the overall success of the migration. We take care of:

Setting up the new Atlassian Cloud instance(s)
Cleaning up and consolidating data in the source instance
App evaluations: Which apps are available in the cloud? Are there alternatives?
Adjusting automations, workflows, custom fields, and permissions
Preparing user management (Identity Provider, SSO, Atlassian Access)
Creating a runbook for test and production migration
Training key users and administrators

Outcome: The technical infrastructure and the project team are fully prepared for the migration process.

Phase 4: Test Migration

Goal: Safely validate the migration process using real data — with zero risk.

Before the live migration, we conduct one or more test migrations. This includes:

Migrating data from the production instance to the cloud
Performing user and permission checks
Testing integrations, automations, and apps
Validating performance and data integrity
Collecting feedback from key users

We document all findings, resolve potential issues, and refine the runbook for the final migration.

Phase 5: Migration

Goal: Successfully execute a smooth and secure transition to the Atlassian Cloud.

We implement the previously tested migration plan — often during a weekend or a pre-agreed maintenance window.

Execute the final migration
Verify all project data, permissions, workflows, filters, dashboards, etc.
Validation by the project team
Activate cloud user access
Support the transition (onboarding emails, tutorial videos, support hotlines)

Outcome: Productive work continues fully in the cloud — without disruption.

Phase 6: Implementation & Optimization

Goal: Ensure user adoption and unlock the full potential of the cloud.

The real value begins after the migration. We support you during the rollout, for example, with:

Webinars & training sessions for different roles (end users, admins, project managers)
Onboarding workshops & change communication
Feedback loops & support phases
Analysis of usage patterns & identification of optimization potential (e.g., automations, new features)
Scaling & expansion of the Atlassian Cloud (e.g., premium features, Atlassian Analytics)

Outcome: Your teams use the cloud to its full potential — securely, efficiently, and future-ready.

OUR TOOLSTACK

Migration Assistants

Supporting tools for Atlassian migrations and AtlasMerge

The Atlassian Cloud Migration Assistant (CMA) is a free tool provided by Atlassian, designed specifically for migrating Jira, Confluence, and Bitbucket to the cloud. It offers a solid technical foundation for migrations — but it does not replace a well-thought-out migration strategy.

At ByteSource, we use the CMA purposefully as a support tool within our migration projects — as part of a comprehensive toolbox. The tool serves as a foundation, but every migration requires additional customization, supplementary tools, and deep Atlassian expertise.

What Can the Migration Assistant Do?

Scanning & Analysis: Detects your current instance structure, projects, users, and permissions.
App Compatibility: Provides insights into which Marketplace apps are available in the cloud — and which need to be replaced or migrated.
Project-Based Migration: Allows you to select which Jira projects or Confluence spaces you want to migrate.
User Management: Supports mapping and transferring users to the cloud.
Wave-Based Migration: Ideal for pilot migrations — e.g., migrating individual teams first, followed by the rest.
Validation & Error Reports: After the migration run, the assistant delivers clear information on successes, warnings, or issues.

When and How Does ByteSource Use the Migration Assistant?

We typically use the CMA starting in Phase 3 (Preparation) — especially in the following cases:

Test Migrations (Phase 4): The CMA allows us to run realistic migration scenarios using actual data.
Production Migration (Phase 5): During the final migration, we rely on the previously tested setup.
Troubleshooting: If something doesn’t work as planned, the CMA enables quick action — including access to logs, mapping suggestions, and detailed feedback.

Good to Know:

The CMA is not a one-click tool. It offers a solid foundation but does not replace a well-thought-out migration strategy and real experience.
Complex scenarios — such as app data, custom permission models, or custom fields — are only partially covered by the CMA.
Our experience: For many manual or unsupported steps, we at ByteSource have developed our own scripts and automations, which we use specifically in customer projects.

ByteSource Tip:

"The Migration Assistant is a great starting point — but not a complete solution. Our experts use it as one tool in the toolbox, not as a cure-all. The real value comes from customization, planning, and post-migration fine-tuning, carried out by ByteSource’s experienced migration specialists — often using custom-developed tools."
