+  (taken from release notes of 4.0 from vendor)
+  If you are upgrading from an older JasperServer version such as 3.5 then
+  you must first upgrade to JasperServer 3.7 before upgrading to 4.0.
+  Upgrading directly from JasperServer 3.5 to 4.0 is not a "certified"
+  (i.e. fully QA tested) procedure.
+
+  The steps to carry out this operation are fully documented in the
+  JasperReports Server Installation Guide for the 3.7 release.  You will
+  need to download the JasperServer 3.7 release package to get the relevant
+  files and documentation. To download the JasperServer 3.7 WAR file
+  distribution zip package, go to the JasperForge.org website and to the
+  JasperServer project.
