Problems while upgrading 6.2(1)E3 to 7.0(4) E4 ...???

[talktobunty83]

Hi all,

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

thanx

Before starting any upgrade work, I would suggest ALWAYS reading through the new version's release notes.  They will provide any warnings, caveats, or special procedures that might be needed before doing the upgrade.  Also, they will list out any basic requirements to use the new software.  Release notes for 7.0(4)E4 can be found here:

http://www.cisco.com/en/US/docs/security/ips/7.0/release/notes/22789_01.html#wp1043779

That being said, it looks like you should have no problem upgrading directly to 7.0(4)E4 from your current version.  From the link:

"The minimum required version for upgrading to 7.0(4)E4 is 5.1(6)E3 or later"

You shouldn't have to worry about the rest of the router chassis and modules, as the IDSM upgrades and reboots independently from the rest of the system.  Just know that the upgrade can take a little while, so be patient while the module reboots and gets started up.

Of course, as with any upgrade, I would make new backups of all configurations and data before installation, just in case something unexpected occurs.

Thanks micheal for you quick reply,

I am concern there are recovery files to download.

Where we use them if something gets wrong while upgrading.

Suppose something gets wrong when I m 6.2(1)E3 to 7.0(4).

Is there any recovery software available, and how to get back to original working sensor 6.2(1)E3

I want to know rollback process.

Thanks
