A plugin is an independent console application that regularly starts to perform various actions, e.g. create some reports and send them by email to specified destinations. When updating a plugin, Replicator delivers the plugin executable file and some other auxiliary files to sites. On installing a plugin, Replicator starts its executable file based on the schedule.
To update a program on the sites, you need to:
Create an update package of an application.
Upload (publish) the update package into Replicator.
Specify the sites to which the update must be delivered and set the installation time.
