Still in the process of upgrading and ran into another minor issue.
In this instance, the upgrade had problems stopping the WebTrends Scheduler service. After 40 minutes I called tech support to report the problem. Here is the solution in case you run into the same problem.
1. Open your Task Manager
2. Click on the Process Tab and sort the list by Image Name
3. Stop the process WTxd.exd
Once this is done, the upgrade proceeded as expected. Word of caution you should wait at least 10 minutes before performing the above steps.
According WebTrends technical support a way to avoid this problem in the future is to stop all the WebTrends services manually before the upgrade with the exception of the MySQL service. The Upgrade need to talk to this database during the upgrade.
One of the major changes in this version is a new backend database. Say good-bye to MySQL and say hello to MS Express (MS SQL Express). So a major part of this upgrade is converting the old data base over. So be sure to make a full and proper back-up of everything before starting the upgrade.
