Data Migration Import/Export made more resilient
Resolved in Pega Version 8.6
The entire data migration operation (export or import) was marked as "FAILED" even if the operation failed for just one type of data. While managing the failure, the operation deleted any completed data flow runs as part of the clean-up and only retained the failed data flow runs for use in further analysis. Because the queued runs could not be deleted, the data migration case became a broken process. At the root of the issue, the data export work item was failing due to one or more DSM service nodes being non-functional based on a validation failure in the case type that runs a check for the presence of functional DSM nodes before starting the data migration operation. This validation can return false negatives, especially on Cloud where the nodes are usually swapped seamlessly without the function realizing it. In such cases, the validation function returned false despite the DSM service nodes being up and running. This has been resolved by adding handling for the failed data migration case by stopping and deleting the open data flows and by disabling the validation which checks for functional nodes.

Fixed scrumboard intermittent failure
Resolved in Pega Version 7.1.9
After upgrading, it was seen that the scrumboard would intermittently fail to load, partially displaying and then hanging if the columns did not fit within the window boundaries due to the number of elements. This was traced to an error in the functionality that resizes parts of the scrumboard, and has been fixed.

Implementation updated to ensure consistent compareDatesByDays results
Resolved in Pega Version 8.6
When using compareDatesByDays in a filter shape within a strategy, the results of the expression were different between the expression test and the strategy test run. This was traced to a difference in handling that became visible after upgrade; giving a negative number for the numberOfDays parameter worked differently in v7.4 than in v8.4. The SSA implementation of compareDatesByDays always worked with the absolute difference in days between dates, whereas the Java function in Pega used in expressions did not, and would compare negative differences as well. To restore the expected behavior, the SSA implementation has been adjusted to not work with absolute differences, and tests have been added to ensure equal results for the Java function in Pega and the SSA implementation.
