Downgrading from Xray 5.x.x to a version less than 3.2.0 implies that you must perform a re-index afterward. This is because from Xray 3.2.0 onwards, the content and format of what Xray indexes have changed.previous version will have the following side-effects on Test Runs with dataset:
Test parameters will no longer be converted on the Test Run page, this includes Test steps Step definitions and Pre-Conditions;
When loading a Test Run created on version 5.x.x, the merge/reset message will be displayed;
When merging a Test Run created on version 5.x.x with the new test step Test Step definition, all step Test Step results will be updated but the reset/merge message will still be displayed;
A Test Run created on version 5.x.x with iterations will be displayed in a "flat mode". The iterations will no longer be available and all the step Test Step results from each iteration will be presented on the Test Steps section.;
After the downgrade, the integrity checker will fail on "Check for invalid Mementos" for all Test Runs created on version 5.x.x. We recommend running the integrity checker before downgrading so we can to get rid of possible invalid mementos.
