If I want to upgrade my IDS-4220, which is currently running 3.0(1)S4, to the latest signatures(3.02.S11), do I need to apply the service pack (3.02.S9), and then run each signature update (3.02.S10, followed by 3.02.S11)? In other words, are signature updates comprehensive, or do they need to be applied one by one in sequence? Thanks.
Signature updates are comprehensive up to the point a new service pack is issued. In other words since you are running 3.0(1)S4 you do not need to add S5-S8 before applying the 3.0(2)S9 service pack, but since there has been a service pack between S4 and S11 you must first apply it before applying the S11 signature set. Does this answer your question?
I believe it does answer my question. Just to be 100% sure though...
I now understand how the service pack factors into the equation, but let's say hypothetically that five signature updates came out after a service pack (S10 - S14), and I've been a slacker and am still using S10. Can I jump straight to S14 without applying the updates in between (S11 - S13)? I'm sorry if I've beaten this to death, I just want to be certain.
The reason that Service Packs break the completness of signature updates is that is how we deliver modifications to the signature engines themselves. So a set of signatures written for a particular service pack binary may be trying to use new engines or new parameter sets that do not exist in older service pack binaries.
