I have this issue.
In the migration process, all the reports and graphs/charts have successfully migrated, however, one chart seem to have an issue.
When I click that chart in the new workspace, it does not show anything. It is just blank.
It has migrated successfully, but still it has this issue.
What could be the reason.
Any suggestions would be useful.
You could use LCM method to migrate reports .The best way is to log on to workspace with the admin id and export all the reports ,All the reports would be exported in a .zip file format. then You can import them into your target via workspace.
