i want to upgrade signature on IDS, but IDS is on E3.
i know i have to use IPS-K9-7.0-2-E4.pkg to directly upgrade to E4.
my only concern, is there anything to take care of before doing this. or while doing this upgrade.
because this router is very important and i don't want to lose anything,
can you people share the information so that i can do this without getting into any problem.
and please note platform is IDSM-2
