Jira Datacenter supports archiving of issues and projects since v8.1. By archiving issues, Jira will remove them from the indexes. The archived issues will still be accessible in read-only mode, however, they will not appear in Jira searches. This enhances Jira performance because it stores less data in the indexes.
Xray supports this feature. Archiving its issue types has the same effect of archiving any other Jira issue type. Additionally, Xray extends this feature by archiving its related data as well.
Archiving Test Executions
Archiving old Test Executions is a good use case for archiving Xray issues, especially if continuous integration processes are used. These can quickly create many Test Execution issues while importing new execution results into Xray on a daily basis. These issues are good candidates to be archived.
Archiving a Test Execution issue automatically archives its related Test Runs as well. Archiving Test Runs will not delete the Test Run information from database, they are just hidden from issue views, reports, gadgets and are no longer used for the calculation of the Test Run Status and Requirement Status. It is still possible to browse archived Test Runs and even navigate into the execution page to see the execution results.
Archiving Tests
Archiving a Test issue automatically archives its related Test Runs with the same effects described previously. Additionally, archived Tests no longer participate in the calculation of the Requirement Status and on the Requirement Test Coverage analysis.
