Ok, thank you all for the feedback we are going to start with the Junos OS
upgrade first on it but have to open the ticket with JTAC since currently
on the juniper support website they have the Junos 15.1 is available so not
sure we can directly jump from 10.4 to 15.1 maybe we have to do step by
step upgrade on it. Any other suggestions will be helpful as well

By the way, the uptime on the Juniper MX chassis was 1589 Days on it.
