Hello,

Thank you

This tip is a little old but still works...


HOW TO CHECK THE CISCO DNA CENTER IMAGE VERSION ON THE APPLIANCE BEFORE INSTALLING?

Find Pre-installed Cisco DNA software version

One use of this tip is to check what version of Cisco DNA software came
installed from manufacturing. To find it out, perform below steps:

1. Switch to another vty with ALT + F2 keys

2. Login with user = maglev and password = maglev (2.2.1.x or earlier)
   Login with user = maglev and password = maglev1@3 (2.2.2.x or later)

3. Check the release version file:
use the command: cat /etc/maglev/release-info.yaml

for example:

$ cat /etc/maglev/release-info.yaml
release_info:
build_date: "Fri Dec 20 17:26:15 UTC 2019"
iso_version: "1.3.0.115.98"
image_version: "1.3.0.115"
hash: "01ecc7b"
iso_type: "full-iso"


4. Then Google for "Cisco DNA Center system version 1.3.0.115"

You should get some hits for "Release Notes". Match the"image_version" to "system version" 
and it should lead you to the version on the appliance.

Note: there may be multiple versions with the same system version. So for this case, 
use the build date in comparsion to the release date and it should narrow the scope.

I've found that the etc/maglev/release-info.yaml doesn't exist anymore on newer deployments. To get to the same image version you can cat the following file:

cat /log/post_install_hook_processing.log

This will show the version number of the installed main package.

New version, not found this file ("/etc/maglev/release-info.yaml")

Any other command for check the version in CLI, my current version is 2.3.5.5
