How does the migration affect our existing apps and integrations? ## How complex is the migration process? The migration process varies depending on company size and the complexity of the existing Atlassian environment. Typical steps include planning, data cleansing, test migrations, and the final migration. Challenges may arise with the integration of third-party apps and the adaptation of workflows. Information about our Atlassian Cloud migration process can be found here: [Atlassian Cloud Migration Best Practices](https://www.xalt.de/en/blog/best-practices-cloud-migration-jira-confluence/). ## What support is available during the migration? Atlassian provides extensive documentation and support, as well as a [Migration Assistant](https://marketplace.atlassian.com/apps/1222010/jira-cloud-migration-assistant?tab=overview&hosting=datacenter). In addition, certified Atlassian Solution Partners are available who can accompany the entire migration process. For complex migrations, it is recommended to work with an Atlassian Solution Partner with Cloud certification. ## How can downtime during the migration be minimised? Thorough planning and test migrations are crucial. It is recommended to migrate outside of business hours when few or no users are using Jira, Confluence, and Co. Also ensure that you communicate the migration to all users in advance and subsequently provide the most important information (such as URL, login, changes, etc.). For complex migrations and the introduction of new software to the workforce, it is also sensible to consider using [Change Management](https://www.xalt.de/en/change-management/) strategies to make the transition as smooth as possible. ## Is the Atlassian Cloud GDPR-compliant and secure? Yes, the Atlassian Cloud is GDPR-compliant and offers robust security measures. This includes encryption, regular security audits, and certifications such as ISO 27001 and SOC 2. Detailed information on security in the Atlassian Cloud can be found on [this page](https://www.atlassian.com/trust/security). ## How does the migration affect existing workflows, customisations and integrations? Most standard workflows and integrations work seamlessly in the cloud. Custom modifications may need to be revised. It is recommended to review, test, and check whether the plugin is available in the cloud for all workflows, integrations, and plugins before the migration. ## What are the cost implications of moving to the cloud compared to on-premises? In the long term, the cloud can be more cost-effective due to reduced hardware and maintenance costs. The cloud pricing structure is based on a subscription model. A detailed cost comparison should be part of the migration planning. You can get an initial assessment of cloud prices here: [Atlassian Cloud Pricing](https://www.atlassian.com/purchasing/pricing). **Success Story: Atlassian Cloud Migration** ## **How FATH saves €200,000 (-80%) per year with the Atlassian Cloud through reduced operating costs for personnel, maintenance, and downtime** [**S**uccess Story](https://www.xalt.de/en/case/fath-atlassian-cloud-migration/) ## How do we prepare our users for the change? Clear communication and training are crucial. Create a change management plan that includes training materials, FAQ lists, and support channels. Introduce pilot groups to collect feedback and make adjustments. Furthermore, we also recommend using change management strategies to plan the changes thoroughly in advance and involve all users continuously in the process. ## Can we migrate all data, including attachments and historical information? In most cases, yes. Atlassian's migration tools support the transfer of data, attachments, and history information. It is important to perform data cleansing before the migration and to check whether special data types require special treatment. ## How does cloud performance compare to on-premises? Cloud performance is generally very good and scales automatically. Atlassian guarantees 99.9% availability for enterprise customers. Actual performance can be influenced by factors such as internet connection and geographic location.

Cloud customers benefit from automatic updates, improved mobility, and new features such as advanced analytics, AI-powered insights, and seamless integration between Atlassian products. ## How scalable is the cloud solution for our future growth? The Atlassian Cloud is highly scalable and grows with your business. You can easily add or reduce users and switch between different plans to meet your needs. ## What happens to our existing licences and how does pricing work in the cloud? Existing server licenses can often be converted into cloud subscriptions. Cloud pricing is based on the number of users and the chosen plan. Atlassian offers migration programs that facilitate the transition. ## How can we consolidate multiple instances or projects during the migration? Atlassian provides tools and guidelines for consolidating multiple instances. This requires careful planning and can be complex. It is recommended to work with us as an Atlassian Platinum Solution Partner and cloud experts to develop the best strategy. ## What training or resources are available to support our team in adapting to the cloud environment? Atlassian offers extensive documentation, webinars, and online courses. The [Atlassian University](https://university.atlassian.com/) section contains specific cloud migration courses. Additionally, customised training can be arranged through Atlassian partners. ## How does the migration affect our existing apps and integrations? Many popular apps are available in the cloud, but not all. Check the compatibility of your apps in the Atlassian Marketplace. Some apps may require updates or alternatives. Plan the app migration as a separate step in your migration process. ## Still have questions about the Atlassian Cloud migration?
