Installing Software Upgrades

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 compact flash 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 compact flash, install the image, and restore configurations.
