Installing Software Upgrades

Use either the J-Web interface or the CLI to upgrade from one software release to another.

Note: For more information on migrating a J Series Services Router to a later version of JUNOS Software, see the JUNOS Software Migration Guide.

Note: Previously, upgrading images on J Series devices with 256 MB CompactFlash card from Release 8.5 onward involved removing unwanted files in the images and removing the Swap Partition. From 9.2 Release onwards, as an alternative, the software accomplishes the upgrade efficiently to take another snapshot of the CompactFlash card, install the image, and restore configurations.
