- Click Next to continue to the next page.
The Select Images page opens. Select a software image as described in Selecting Software Images To Deploy.
Selecting Software Images To Deploy
The Select Images page includes a table listing each device group and device that you selected for deployment. See Table 1 for a description of the table columns.
If you selected the Upgrade only (Install previously staged image on device) option, only devices that contain a previously staged software image appear in the table. You cannot select a different image to install on these devices.
To select the software images to deploy, perform the following steps on the table row for each device group or individual device that you want to upgrade:

|All Device Types|
Delete any existing image before download
Select to delete any existing software images on devices before downloading the new software image.
Reboot device after successful installation
Select to reboot the device after the software image is installed. A reboot is required to begin running the new software version on the device.
Note: This option might get disabled based on your details that you specify in the remaining fields. This indicates that for the options that you specified, the system automatically reboots the device as per the requirement during or after the image upgrade.
Check compatibility with current configuration
Select to validate the software package or bundle against the current configuration as a prerequisite to adding the software package or bundle.
Select if you want to perform an in-service software upgrade (ISSU) or a nonstop software upgrade (NSSU).
ISSU enables you to upgrade between two different Junos OS releases with minimal disruption on the control plane and with minimal disruption of traffic.
NSSU enables you to upgrade the software running on an EX Series switch with redundant Routing Engines or on most EX Series Virtual Chassis by using a single command and with minimal disruption to network traffic
Archive data (Snapshot)
Select to take an archive snapshot of the files currently used to run the switch and copy them to an external USB storage device connected to the switch.
Copy to alternate slice
Select to copy the new Junos OS image into the alternate root partition. This ensures that the resilient dual-root partitions feature operates correctly.
This option is available only if you select Reboot device after successful installation.
Use Hitless Upgrade
Select to use the hitless upgrade process to upgrade the devices. Applies only to WLC controllers in cluster mode.
Stage later time
Select Stage now to start staging software images to devices as soon as the job runs.
Select Stage later time to schedule the staging for a later time.
If you selected Stage later time, enter the date and time for staging to start.
Upgrade later time
Select Upgrade now to start upgrading software images on devices as soon as staging finishes.
Select Upgrade later time to schedule the software upgrade for a later time.
If you selected Upgrade later time, enter the date and time for upgrade to start.
If you scheduled staging, you must schedule the upgrade for at least 10 minutes after staging, to ensure that staging completes before upgrade starts.
