If a new version of OSLC Connect for Jira has been released you only need to update it using the UPM (Universal Plugin Manager).
That's it, no more actions are required on Jira . Enjoy the new connector release and features.
 If IBM Engineering Lifecycle Managementglobal configurations or IBM Jazz Reporting Service / IBM Engineering Lifecycle Optimization - Engineering Insights (ENI) are being used
by any Jira project administrator, advise the IBM Link Index Provider (LDX) and IBM Lifecycle Query Engine (LQE) administrators to verify the Jira datasources and to re-index in the case an error status was reported
after the upgrading. This is a very important task in order to keep synchronizing those applications with Jira. On Reindexing an LDX/LQE datasource topic,
LDX/LQE administrators can find a guide to do it.
