Dear ALL ,
One of customer is planning to upgrade juniper routers .
Current running version is 11 and 12 .Customer wants to upgrade to 14 .
Can someone please suggest upgrade path from 11 to 14 and 12 to 14 .
thanks in advance .
From 11 version, you need to be on 11.4 version of Junos. From here you can directly go to 12.3 and from there to 14.1.
i.e 11.4 > 12.3 > 14.1
From 12 version, you need to go to 12.3 from where you can directly upgrade to 14.1.
