This instruction describes how to migrate Checklists created by Smart Checklist addon from Jira Cloud to Jira Server/Data Center. I’s based on Atlassian recommended method o XML backup
More details on this: https://confluence.atlassian.com/adminjiraserver/migrating-from-jira-cloud-to-server-applications-938846963.html
Check how to migrate from Jira Srver/DC to Jira Cloud here → https://railsware.atlassian.net/wiki/spaces/CHKSDC/pages/2350088314
☝🏼NOTE: There’s NO need to have Checklists and Smart Checklist Progress Custom Fields to be set on Cloud instance. Data would be pulled from Jira Issue Properties
Prepare Backup on Jira Cloud:Go to System → “Import and Export” section → Backup manager → Backup for the server
Restore Jira data from Backup on Jira Server:Go to System → “Import and Export” section → Restore System → Restore Jira from backup
Then install "Smart Checklist for Jira" on the Server → go to add-on Settings → Global Settings → Start Migration☝🏼NOTE: Make sure you have Smart Checklist older than 5.3+ and above version installed.
Once migration is completed - Smart Checklist values would be successfully migrated from an Issue Property to a new Data Storage (Database) and custom fields would be synced as well.
Check if the migration was successful in the Issue Search view by adding Smart Checklist Custom Field
That’s it! Hope everything works for you 🙌🏻
