Packet will flow as normal during upgrade as the IDSM is in promiscuous mode. Upgrade also requires a reboot as well.

Thanks helijenn for your reply,

i am concern about what would be the rollback process if something goes wrong while upgrading.

like i mean how to get back to 6.2(1)E3 if something goes wrong.

You can reimage the IDSM back to version 6.2.1(E3), however, we don't see many issues with upgrade to version 7.0.

I would suggest that you take a backup copy of your configuration prior to upgrade.

can you please explain process of system reimaging.

because i lost in the concept of application and maintenance partition

after doing system re-imaging.

do i really need to do last step initialisation of IDSM using setup command or i can use copy command to upload my backup config to current config.

will it solve all problems???

Here is the difference between upgrade and reimage:

Upgrade - configuration will be kept as it is.

Reimage - configuration will be wiped out, and you would need to reconfigure the IDSM at least running the setup command for basic network connectivity.

Please do not reimage the IDSM unless it is necessary.

If you are trying to upgrade the IDSM, please use the upgrade file to upgrade it, and if and only if the upgrade fails, that is when you would need to perform system reimage.

yeah i got what u mean,

but in our organization we can't make changes without knowing the full rollback procedure.

and one last question,

when i go to cisco to download files

IPS Manager Express (IME) Software
Intrusion Detection System (IDS) Recovery Software
Intrusion Detection System (IDS) Signature Updates
Intrusion Detection System (IDS) System Software
Intrusion Detection System (IDS) System Upgrades
Intrusion Prevention System (IPS) Recovery Software
Intrusion Prevention System (IPS) Signature Updates
Intrusion Prevention System (IPS) System Software
Intrusion Prevention System (IPS) System Upgrades

please correct me if i am wrong.

System software are system images.

sytem upgrades are like engine upgrades,

Signature updates are normal singnature update on specific engine.

What is the difference between IPS and IDS files.

and where and when we use recovery software
