Best Practices
Installation and License
To perform migrations to the Cloud from Server/ Data Center, you must install the Cloud Migration Tool on the Jira Server or Data Center instance and Configuration Manager on your Jira Cloud site.
It is recommended to have the latest version of the Configuration Manager Cloud Migration Tool installed on the source Server/Datacenter so that it has the latest features and bug fixes. You can check the latest compatible versions from the following link:https://marketplace.atlassian.com/apps/1224900/configuration-manager-cloud-migration-tool/version-history. Visit the installation instructions.
You must have the Standard, Enterprise, or Premium cloud plan on the destination Jira Cloud site. Trial or paid licenses of these three types are supported. Migrations to Jira Cloud on the free plan are not supported.
Pre-migration checks
Performing the Jira Integrity Check and fixing the errors on your instance before the migration is recommended. Please refer to https://confluence.atlassian.com/adminjiraserver/using-the-database-integrity-checker-938847667.html
If you have the CMJ’s Integrity Check for Jira app https://marketplace.atlassian.com/apps/1212168/integrity-check-for-jira?hosting=datacenter&tab=overview installed in your source instance, it is recommended to run the Integrity Check Integrity Check on the source Server/Data Center and fix the errors before migration. You can install a trial version of the app.
It is recommended to perform a test migration before the production migration to capture likely issues in your instance.
Create a migration runbook that includes each step in the process, instructions for those steps, who will complete them, and how long they’re expected to take. It will help production migration run smoothly and according to the plan.
Please check and understand what configuration elements are supported: Supported Configuration Elements.

the Cloud API https://private-api.cmj.botronsoftcloud.com/ and file storage https://prod-cmjc-snapshot-upload.s3-accelerate.amazonaws.com/
Ensure no scheduled jobs are set to run on the instance during the planned deployment period.
Please check/monitor the network firewall to see if it is causing performance limitations that may slow/block the deployment process.
...
Always perform the deployment process during non-business hours when there is minimal or no user activity to ensure optimal functionality.
Ensure users have a valid email address on the source; otherwise, it will be reported as a problem during migration. See User Management for more information.
Access and Permissions
You should have Jira System Administrator or Org Admin permissions on Jira Server/Data Center and Jira Cloud to create connections and perform migrations.
You should have an Atlassian API token for your Atlassian account. Check API Token about why you need an API token and how to get one.

Support
If the migration fails, please collect the Deployment ID and provide it to us by opening a support ticket in the Support Portal. Refer to our article How to find the deployment ID when a deployment fails using CMJ Cloud.
Also, we advise you to download a 'Support Zip' (which contains information and logs from your Jira system and Cloud Migration Tool) and attach it to the support request. Refer to https://confluence.atlassian.com/support/create-a-support-zip-790796819.html.
