Links Missing After an Import
Problem: After an import, remote links or Confluence links are missing. After migrating a complete project between two instances, issues in the source instance which had links to external websites or Confluence pages no longer contain these links inside the target instance.
Solution: Project Configurator does not support creating remote issue links to Confluence pages created by an application link. Project Configurator uses the project import functionality provided by Atlassian to import incomplete projects, and this functionality provided by Atlassian does not maintain these links.
The JRASERVER-34362 Atlassian ticket confirms this functionality is not supported and provides a workaround to recreate the links for each issue using the REST API after the project has been imported.
