Problem
After upgrading to R4J - Requirements Management for Jira version 4.x from 3.x, all coverage views have disappeared.
Solution
From R4J 4.0.0, major architectural changes in the coverage views have been applied.
Due to this, all saved coverage views must be migrated manually to the new coverage services when upgrading to R4J 4.x from any version older than 4.0.0.
To do this, follow the steps below:
Go to add-on administration
Select R4J - Requirements Management for Jira > Migrate Filters
Follow instructions on the screen
The migration may take a while depending on the number of saved coverage view filters you have. For further troubleshooting, below are some guides to solve some known issues with the migration.
