We have a Agile board (configured for project ABC, & filter is configured using JQL query like below):
project = "ABC" ORDER BY Rank ASC
Now, say project ABC has been renamed to XYZ, then you can't see any issues under Agile board since board still uses filter JQL query which points to old project with name ABC.
Solution looking: So actually if project is renaming from ABC to XYZ then it should reflect at each and every place including JQL filer query. I think this is an issue with jira & needs to be rectify.
Jira System should able to update name at each & every place in system, as its not possible for user to go & check/change in each and every board that used old project name.
