All Jaspersoft views and reports now show a created date the same as the date of the upgrade from PPM 14.4.0 to 15.4.1.

Is this to be expected after a PPM upgrade? 
Once an upgrade is performed, the existing organization is deleted and then repopulated resulting in report time stamps reflecting the upgrade date and not the date when the reports and view were initially created.

The recommendation is to export the reports, views or the organization. Then post upgrade, import them back, and this will retain the original dates.
