does it requires a fresh installation or upgradation path?

Re: upgrading IPS from 4.1(5) to 6.0


There is a readme file that advices on this.

You must upgrade version 4.X and earlier sensors to 5.0(1) before applying the 6.0(1)E1 major version upgrade.

Refer to the Release Notes for the Cisco Intrusion Prevention System 5.0 available at the following URL for instructions on upgrading to 5.0(1):

Installation of the 6.0(1)E1 major version results in a complete re-imaging of the sensor. While the sensor configuration settings are maintained, all data written to the event store as well as any unsupported customizations will be lost.

what should be the approach? go for a fresh installation of 6.0 or follow the upgradation path as suggested

If you have been actively monitoring and configuring your 4.1 version then the upgrade path would be preferred.

This way your current configuration can be converted automatically during the upgrade to work with the higher versions.

If your sensor has a lot of tunings it could take several days trying to do this conversion manually from the older 4.x commands to the newer 6.x commands; so you would want to let the upgrade scripts do the conversions automatically for you.

But, if your current 4.1 version has just been sitting on the shelf or has very little site specific configuration, then a fresh installation of IPS 6.0 from a System Image may be the way to go.

This way you won't have to worry about any upgrade issues or what somebody else put on the box months or years ago.
