[j-nsp] Upgrading from RE-S-2000-4096-S/SCB-MX960-S to RE-S-1800X4-32G-S/SCBE2-MX-S

[craig washington]

Hello smart people.


We are in the process of upgrading from the aforementioned in the title.

My question is does anyone have a procedure they have used in the past for doing this or any type of gotchas.

We are also replacing the old DPC's for MPC's.

I know the port numbers will change and that the MPC's aren't compatible with SCB.

So I am looking for something like what's the best process to follow, for instance should I:


  1.  Swap out RE-2000 for RE-1800 one at a time (leaving SCB in place) to get the configuration over and sync and then once that's up swap out the SCB for SCBE2 and also swap out the DPC's at the same time?


Juniper documentation suggest powering off the entire router when going from SCB to SCBE2 so figured I would make sure the RE's are good and code is up to date before powering off and swapping out SCBE2 and DPCs for MPC's.


Thanks again and all feedback is welcome.
