Hi Adam,

I am using the TurnKey linux Observium appliance and as per your instructions I have downloaded the latest version of the appliance and now I am at the process to export the database from my previous Observium appliance.
During the initialisation I wasn't able to import the dump from the original install so I will perform the import after the initialisation. Does this affect the new system in any way?
Also should I create dump of all the databases or just the phpmyadmin which is the database of the old system?

Old Observium appliance New Observium appliance

Thank you,
Marios

Observium is just a MySQL database, a config.php and the contents of the rrd directory.

The easiest way to migrate is just to run the install process on a new system, but replace the database insertion step with inserting a dump from the original install, and then copying over the config.php and rrd directory.

Adam.

Hi,

Is it possible to migrate my current Observium configuration to a new VM and if yes is there any guide how to do it since I am not very familiar with the specific system?

Thank you,
Marios

Debian 7 is like 3 years out of security support. Are you sure you want to be running something with that much access on your network devices on it?

But yeah, PHP 7 has been a requirement for a while now...

Hi,

You likely just need to update PHP to a recent 7.x release and it should work.

I'm sure there are lots of guides on installing PHP 7.x on Debian 7 around :)

Hi,

We have updated our Observium platform to the latest version CE 19.8 and we are facing the following issue.
After finishing the upgrade using the instructions on the website we were able to access the web interface just once. When we logged in the first time after the upgrade we received a message that the php version also must be updated. After that we were unable to logon to the web interface (after login we see a blank screen) and we receive the following error in the apache error log:

[Wed Sep 16 12:33:07 2020] [error] [client PHP Fatal error: Call to undefined function password_hash() in /opt/observium/html/includes/authentication/mysql.inc.php on line 101,

Is it possible to backup the configuration and update php version and use Observium installation again? If yes is there any guide how to perform the update?
We have observium installed on a Debian 7 machine.
