Migrating to cloud can be a challenging move for any organization: there are many moving pieces to keep track of, and with the threat of negatively affecting both internal and front-facing operations, failure is not an option! Here are some key blockers to keep in mind when migrating to Atlassian Cloud from on premise instances, so that you can review ahead of time just how prepared for a successful migration your company is:

• User Management
• Automations
• Size of Attachments
• Apps

User Management

User Management and how users are set up is a major difference when operating in Atlassian Cloud versus on premise. This is an important obstacle to understand and address, as the approaches for user management are different between cloud and on-premise. Key to this is how users are created and managed; equally important is identifying any users with missing or duplicate email addresses, since these cause problems with data integrity and users being able to use Filters and Queues in Atlassian Cloud. 

Automation

Automations are critical to research, as some automations may not be functional or even allowed in Atlassian Cloud: these will need to be identified and assessed to determine the balance between the value they bring and the level of effort of recreating them. 

Attachments

Size of Attachments becomes critical when using the Jira Cloud Migration Assistant, as this does not support migrating Jira Service Desk projects, which may require importing data via Site Import that forces attachments to be uploaded separately in 5 GB chunks, one chunk at a time. This alone will drive the migration of attachments to exceed a typical outage window, as the Site Import process must first conclude prior to uploading attachments. 

Jira Service Management utilization is tied to the size of the attachments as noted above. While JSM is used heavily it is currently not able to be migrated using the Jira Cloud Migration tool. With that being said this drives the use of site import. With this comes having to migrate the users and attachments separately. This becomes more moving parts during the migration outage and the coordination and timing will become even more critical.  

Apps

Jira Suite Utilities (JSU) / Jira Miscellaneous Workflow Extension (JMWE) / Scriptrunner are apps available in the Atlassian Marketplace that may be used in one or more of your current workflows. While these apps have helped to drive the creation of workflows and processes to automate certain transitions or enforce proper data collection, there is also no current migration pathway to Atlassian Cloud. While JSU has become part of the native cloud, JSU along with the other two apps must be manually fixed in all workflows migrated up to the cloud. You must run a query on your on premise data base to ensure you map out all transitions affected by the apps. Then once the migration to cloud is complete, they must be reviewed and recreated manually to ensure they are all working properly. Where possible utilizing the out of the box options, that mimic JSU, can help to move away from at least one app. 

Specific to Scriptrunner, one common scenario is the use of it in filters can cause them to no longer function, potentially causing boards and dashboard to render incorrectly. These filters must be rewritten using the Scriptrunner Enhanced Search functionality. One good example is any filter that contains the phrase "issueFunction not in" will need be rewritten as "NOT issueFunction in". It would be advisable, when doing the migration to Cloud, to open a ticket with the vendors for advise on how to fix scenarios with JQL that worked in Server/Data Center that no longer work "as-is" in Cloud.

Overall these key obstacles will get you on the correct path to understanding what you know will need to be done in preparation for starting the migration. This by no means is a complete list of the only obstacles that you can encounter, but we hope it will help you to be proactive in fixing obstacles before they become a blocker to the migration.
