Prasanth,


You're right. 4.7.1 upgrade is through ISO and the .tar.gz option isn't available. For 4.7.2, if you use the ISO then you reimage it. To upgrade to 4.7.2, you have to use the .tar.gz.

Yes to number 1.

For going to 4.7.2 you'll have to use the .tar.gz file, NOT the ISO. If you use the ISO, you'll re-image your device. Also you have to run the .tar.gz upgrade script from the console and not in a SSH session!

Prasanth,


You'll have to go to 4.5.x or 4.6.x, and then jump from there to 4.7.2. Make sure you take backups along the way.

Thanks a lot for the reply.


Isn't it possible just to insert the 4.7.2 ISO cd and do an upgrade?

Prasanth,


Unfortunately no. If you insert a CD, you'll end up re-imaging it. Use the .tar.gz file from Cisco's site and be at 4.5 or 4.6 already before you go to 4.7.2

Hi,


Just want to confirm


1) Use cca_upgrade-4.6.1-NO-WEB.tar.gz first to convert from 4.1.3 to 4.6.1

2) Use the iso or cca_upgrade-4.7.2-from-4.5.x-4.6.x.tar.gz

Am I right?


Can I use cca_upgrade-4.7.2-from-4.5.x-4.6.x.tar.gz on the webpage to do the upgrade whn i upgraded the software to 4.6.1?

Hi ,


Thanks again for making things clear to me.


Once I had upgrade the version 4.6.1 to 4.7.1 using iso cd. Using the option " upgrade over serial console"

Is 4.7.2 having different approach than 4.7.1??



Thanks Again
