Thanks Craig. This is much appreciated. I must admit the documentation had me scratching my head a little.

Good to know - but due to the change in the community website, I had to find that out on my own. But anyway thank you for your valuable input!

But it would also be great, if that would have found the way into the official documentation.

And in addition I think, it would be nice to include the necessity, to upgrade the postgresql version of the embedded database with this script before you start the upgrade, in the upgrade documentation.

I first downloaded the 24.4 update, then added some additional space to the virtual disks, rebooted and started to import the update with zman sui. There I got the error, that the embedded database has the wrong version as it needs a minimum of 16.4 and that I should proceed after having that updated. I then had to search for this utility, as the update documentation had no hint to this script. And even the documentation of the script is more a hole than a documentation. So I had to inspect the script file and the content of the zip-file to come to the method you have described here quite well. And of course I had thought, that the script is correctly marked as executable, if I unzip the zip-file on the appliance itself to find out, that this step has to be done manually, too.

But after that, the update ran smooth on the primary server and is now rolled out to the devices. The few devices I have updated as a test got no problem till now.

In regards to the Documentation...I did create a Doc Defect to provide more details.  Sometimes when really knowledgeable folks write stuff, they forgot others do not live and breathe the same things and Admins have to be an expert on a myriad of items in the I.T. world.

When prompted for an administrative account, the value will be "Case-Senstive" so the built-in account will be "Administrator" and not "administrator", even though most other places "administrator" will work  ---> is one of the most important sentences in the description: Please mark in red

zman dgc, gdcs and other commands that output the user and PW for the Postgres are important when you need to communicate directly with the database.

Thank you for the important information

In fact you need to look into your configuration, what the name of the local administrator is. It is often "Administrator" but you can have any name, which is allowed as administrator. In my installation it is for instance "ZenAdmin"

You just caught me on the wrong foot, the default admin in ZEN is the administrator, additional administrators can be created as non ldap with different roles, but as far as I know the administrator cannot be deleted from ZCM.
