Upgrading from versions < 3.2.0

...

If you are upgrading from a version lower than 3.2, this implies that an upgrade task will run to pre-calculate historical data. This action is a one time action and it will run in the background, so that Xray is still available during upgrade. A re-index operation of your Jira instance is required so that the internal data becomes searchable and usable by Xray.

Upgrading from versions >= 3.2.x

...

If you are upgrading from v3.2.x to v3.4.y, you must recalculate data in Xray configuration section → Custom Fields. This recalculation is necessary because of a huge improvement in the amount of data that Xray needs to add to the table and to Lucene indexes.
