*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

Hello!
The GGSN RE in a J20 (it is not a M20 ;-) is not running standard
JUNOS.
It is JUNOS + Ericsson software module handled by Ericsson. So you
need
to be running this "special" JUNOS version controlled by Ericsson and
get it from them. Dont download a JUNOS from Juniper homepage and use
that, it should not work AFAIK.
Cheers

One of my customer is using M20 as GGSN in their GSM network.
They had two RE and Primary RE got HW problem so they unplugged it
from Router. Now they have got their replacement HW from JTAC.
What would be the procedure to adding New RE to GGSN (M20)
without interrupting service? JUNOS version of New RE is 9.5 where
as currently running RE's 8.0.
I've search Juniper site and have gone through the documents.
Sharing practical experience would be great for me.
Please advice. If you need any further information, let me know.
