Hello colleagues,
I am planning to upgrade 10 QFX5100 switches VCF and 4 EX4300 switches VC using NSSU to minimize the outage as much as possible.
(previously we did that manually by dividing into half and rerouting traffic then upgrade each half and after join the VC, but it took a lot of time to plan and implement and outage during the reroute was sometime 30 sec)
and since I haven't used NSSU before, I got few questions:
- Our current version is
18.1R3-S10.4 and planning to upgrade to the juniper TAC suggested one Junos 18.4R2, but checking NSSU allowed versions there is no NSSU to this suggested version, there is only NSSU to 18.4R3
So If I want to use NSSU I can not upgrade QFX5100 & EX4300 to the suggested version?
