This chapter discusses the difference between Traffic Manager software restarts and full host reboots.

## Software Restarts

The Configuration Importer automatically restarts the Traffic Manager software on all cluster members if a changed configuration setting requires a restart to take effect.

In some circumstances, you might want to disable this behavior and delay restarts to happen at a later time, such as during a maintenance window. To disable automatic restarting of the software, supply the "--no-restart" argument to the "config-import" tool, or add "--no-restart" to the ZEUS\_CONFIG\_IMPORT\_ARGS environment variable when launching a Docker container. By using this argument, you must manually restart your Traffic Managers at the appropriate time for pending changes to take effect.

## Host Instance Reboots

Some configuration changes might require a full host instance reboot to take effect. This is not an automatic process and must be performed manually on all cluster members. Ivanti recommends you schedule a full reboot to take place at a time of least impact to your services.
