The attached document is an upgrade guide that will take you thru the steps and the important considerations for the upgrade to the latest and exciting release of DevTest.
Remember we now support in-place upgrade from 8.x to 10.1 which means you can install in the same location as your prior release and you can also use you existing database which will be upgraded automatically for the 10.1 release!!
If you are planning in place upgrade from versions prior to 8.5 to 10.2, make sure you set the property lisa.database.migration.safeguards to false in local.properties. It is true by default. It is important to ensure that the db user has dba level privileges during the upgrade.
