Jira Cloud Migration Assistant (JCMA) Error: Please remove these share permissions and re-create them after migration
Platform Notice: Cloud, Server, and Data Center - This article applies equally to all platforms.
When running a migration plan to migrate Jira Server projects to Jira Cloud, the Jira Cloud Migration Assistant (JCMA) plugin may report errors regarding share permissions tied to migrating projects.
Jira Server with Jira Cloud Migration Assistant 1.0 and higher
2021-01-05 04:23:44.202 ERROR ALPHA project-export Board 'ACME BOARD' is shared to users of other projects: BETA. Please remove these share permissions and re-create them after migration.
In this example error block, project ALPHA migration has failed because board: ACME Board is also shared to the BETA Project.
This error is thrown because boards associated to projects included in a migration plan are shared to other projects that are not a part of the migration plan. Since this is a dependency issue, JCMA alerts you to the problem and does not proceed with the project migration.
Go to the board mentioned in the error message
Click on Board → Configure
Click on General and Filter → “Edit Filter Shares”
Remove users or groups that were referenced in the error log from the affected board
Re-attempt to migrate the attached project through the Jira Cloud Migration Assistant
Keep in mind that to make these changes, Jira Server Admins will need the Create Shared Objects global permission in order to make config changes to any Shared Filters. If even after assigning the needed permission the admin still doesn’t display the Edit Filters Share link, the filter may belong to another user and the admin may need to transfer ownership of the filter to themselves before attempting to remove it from the board. You can change ownership of the board by following the documentation here: Changing the ownership of a shared filter.
