When you schedule a distribution, you schedule the distribution of the Grid Master as well as the upgrade groups, including the Default group. The Grid Master distribution must always occur before the distribution of the upgrade groups.

To schedule a software distribution:

1. From the **Grid** tab, select the **Upgrade** tab, and then click **Distribute** -> **Schedule** **Distribution** from the Toolbar.
2. In the *Schedule* *Distribution* editor, complete the following:
  - **Activate** **Distribution** **Schedule:** Select this to enable the distribution schedule. Clear this if you are creating a distribution schedule you plan to activate at a later date. You can configure and save information in this editor even when you deactivate a scheduled distribution.
  - **Grid** **Master** **Distribution** **Start** **Information:** Enter a Grid Master distribution date, time, and time zone. The distribution date and time must be before those of the upgrade groups.
    - **Date:** Enter a start date of the Grid Master distribution in YYYY-MM-DD format. You can click the calendar icon to select a date from the calendar widget.
    - **Time:** Enter a start time of the Grid Master distribution in hh:mm:ss AM/PM format. You can also select a time from the drop-down list.
    - **Time** **Zone**: Select a time zone that applies to the start time you enter. If this time zone is different from the Grid time zone, the appliance converts the time you enter here based on the Grid time zone, after you save this schedule. When you display this schedule again, it displays the converted time. Selecting the time zone here does not affect any time zone settings in the Grid.
    - **Admin** **Local** **Time:** Displays the Grid Master distribution start date and time in the time zone of the administrator[.](https://infoblox-docs.atlassian.net/wiki/spaces/nios90draft/pages/73273046)
  - In the upgrade group table, specify the following for each upgrade group by clicking the corresponding field in each row:
    - **Start** **Distribution:** Specify when the distribution occurs. Select one of the following from the drop-down list:
      - **Date/Time:** Select this to configure the distribution start date, time, and time zone.
      - **After** ** *****<group>***** **: Select **After** **Grid** **Master** to start the distribution immediately after the completion of the Grid Master distribution. Select an upgrade group that must complete its distribution before the group you are configuring. When you select this option, you cannot enter a date, time, and time zone.   
**Date**, **Time**, **and** **Time** **Zone** are enabled only when you select **Date/Time** for **Start** **Distribution**.
      - **Date:** Enter a distribution start date in YYYY-MM-DD format. You can click the calendar icon to select a date from the calendar widget.
      - **Time:** Enter a distribution start time in hh:mm:ss AM/PM format. You can select a time from the drop-down list.
      - **Time** **Zone:** By default, the appliance displays the time zone of the first Grid member in the Upgrade Group. You can change this time zone if you want to enter the time using a different time zone. After you save the schedule though, the appliance converts the time you entered to the time zone of the upgrade group, if it is different.
      - **Admin** **Local** **Time:** Displays the start date and time in the time zone of the administrator.
      - **Distribute** **to** **Members:** Indicates whether the distribution within the group occurs simultaneously or sequentially. You cannot edit this field here. You define this when you create the upgrade group.
3. Save the configuration and click **Restart** if it appears at the top of the screen.

Grid Manager confirms that the schedule is saved and indicates whether the distribution schedule is active. You can click the Refresh icon to refresh the information in this panel.

Note that the appliance does not save the schedule and displays an error message if the schedule contains the following:

- Circular dependencies between upgrade groups. For example, the distribution of Group A is scheduled after Group B, and the distribution of Group B Is scheduled after Group A.
- The distribution time is in the past.
