[j-nsp] Experience of Adding New RE in M20

[raymondh (NSP)]

*Thinks* Hopefully the under mentioned helps if I didn't make any  
mistake. Ha !

Ensure your new routing engine has all the necessary storage space
Do a snapshot on your GGSN box
Use the primary RE to do the upgrading on the secondary RE by  
specifying the engine slot
*** Either one / Which applicable
- Use the customized jinstall referred by your vendor / principal (if  
there's any)
- Upgrade your JUNOS to the required version and install the  
customized jbundle (if there's any)
Duplicate your license from primary RE to secondary RE
Upon confirmation of the secondary RE, do a commit synchronization  
from the primary RE and you're done

If as per what Patrik if you're using an Ericsson solution, please get  
the packagee from Ericsson and do the necessary. Alternatively you can  
still locate the images inside /var/sw/pkg (Make sure you know what  
you're doing)

Do remember about your licenses if it's tied up with the JUNOS.

Do take precautionary measures, plan for a maintenance window for it  
and the usual procedures
