Before migrate CSAT:
You need to migrate core Jira data of a project with Jira Cloud Migration Assistant and make sure project key in Jira cloud is the same with project key in Jira Server.
Migration:
In Jira Server:
Go to Manage Apps → CSAT Cloud Migration.
Select a project and click Export. Please make sure you have csat data in that project.
A dialog will appear after csat is done working. Click Download to download csat-export.zip file.
Please extract the zip file and you will receive csat-migration-data.csv
Then, go to Jira cloud.
In Jira Cloud:
Please make sure you have done migration core Jira data and enable CSAT for that project.
After everything is done, go to Apps → Manage your Apps → CSAT Import. You will see this page.
Click choose file and import csat-migration-data.csv and then click Migrate button. CSAT will migrate the data. Please wait until the progress bar is complete.
Important note: During the migrate process, If CSAT cannot get recipient information (different between user in Jira cloud and Jira server, missing custom field, … ), It will get recipient by the current CSAT configuration in this project. So that in some case, recipient in ticket maybe different.
