Unified ISSU PIC Support Considerations

Copyright © 2017, Juniper Networks, Inc.
NOTE: Starting with Junos OS Release 16.1R1, while performing a unified
ISSU from a FreeBSD 6.1-based Junos OS to an upgraded FreeBSD
10.x-based Junos OS, the configuration must be validated on a remote host
or on a Routing Engine. The remote host or the Routing Engine must be
running a Junos OS with an upgraded FreeBSD. In addition, only a few
selected directories and files are preserved while upgrading from FreeBSD
6.1-based Junos OS to FreeBSD 10.x-based Junos OS. See
OS with Upgraded FreeBSD
The following sections list the PICs that are supported by unified ISSU.
