Upgrading or downgrading Junos OS might take several hours, depending on the size and configuration of the network. · Upgrade and Downgrade Support Policy for Junos OS Releases on page 3 · Basic Procedure for Upgrading to Release 15.1X53-D496 on page 3 Upgrade and Downgrade Support Policy for Junos OS Releases Support for upgrades and downgrades that span more than three Junos OS releases at a time is not provided, except for releases that are designated as Extended End-of-Life (EEOL) releases. EEOL releases provide direct upgrade and downgrade paths--you can upgrade directly from one EEOL release to the next EEOL release even though EEOL releases generally occur in increments beyond three releases. To upgrade or downgrade from a non-EEOL release to a release more than three releases before or after, first upgrade to the next EEOL release and then upgrade or downgrade from that EEOL release to your target release. For more information on EEOL releases and to review a list of EEOL releases, see https://www.juniper.net/support/eol/junos.html. Basic Procedure for Upgrading to Release 15.1X53-D496 When upgrading or downgrading Junos OS, use the jinstall package. For information about the contents of the jinstall package and details of the installation process, see the Installation and Upgrade Guide. Use other packages, such as the jbundle package, only when so instructed by a Juniper Networks support representative.
