Upgrade considerations if you are using the email notification service

From WSRR V7.5, the email notification service is replaced by a new email subscription notifier. If you are upgrading from a version of WSRR before V7.5, and you are using the email notification service, your configuration settings are migrated automatically to the new email subscription notification configuration. After you have completed your upgrade, email notification messages continue to be generated as before.

The following configuration tasks are completed automatically during upgrade:

A new subscription notifier plug-in configuration file is created, which defines the email subscription notifier.
A default subscription notifier plug-in scheduler configuration file is created, which enables and schedules the email subscription notifier to run at a specified interval.
The following line, which enabled and scheduled the email notification service in your previous version of WSRR, is commented out of the NotificationProperties configuration file:
```
emailNotification=<true|false>,<intervalTime>
```
where <true|false> indicates whether email notification is turned on or off, and <intervalTime> is the scheduled interval time, in seconds, at which the email notification service will check for events that have occurred in WSRR, and send notification messages to subscribers.
The value of the <true|false> setting is copied to the <enabled> element in the subscription notifier plug-in scheduler configuration file, and the value of the <intervalTime> setting is copied to the <interval> element.
