Atlassian Installation, Migration and Upgrade

A Seamless Transition to a Stable, High-Performance and Scalable Platform


Migrating to Atlassian Cloud, Data Center, or upgrading your existing tools is far more than a simple data transfer. It’s a strategic project that requires thorough planning, deep technical expertise, and a strong understanding of your business challenges.

At Andemex, we support you at every stage of your migration or upgrade journey to ensure security, performance, and business continuity.

Why Migrate or Upgrade Your Atlassian Tools?


There are many reasons to make the move:

  • End of support for Server or outdated versions
  • Desire to migrate to the Cloud for greater flexibility
  • Need to improve performance or security
  • Objective to consolidate multiple Atlassian instances
  • Cost and license optimization

However, poorly planned migrations can lead to:

  • Critical service disruptions
  • Data loss or corruption
  • Functional incompatibilities
  • Team disengagement during the transition



Our Tailored Migration and Upgrade Services


We handle all types of scenarios:

  • New Atlassian instance installations (Cloud, Data Center, hybrid)
  • Data migrations: Jira Server to Cloud, Confluence to Data Center, instance mergers, etc.
  • Version upgrades: planning and secure deployment of major releases
  • Cloud transformation: compatibility audit, migration roadmap, testing & go-live support

Our goal is to ensure a smooth transition with no disruption for your users, while guaranteeing the stability and robustness of your target environment.
