George, 

couple of weeks ago I was migrating Observium from one server to secondary. The steps I followed:
1. stop observium on the current server means stop cron in services and http server. 
2. dump mysql database
3. copy all rrd files to the new destination (ftp, sftp, rsync). Better approach is pack current RRD structure via TAR and GZIP and move just single file. I was moving around 64GB of files and process took almost 2 days.
4. create new DB on the new server and restore dumpfile into this DB
5. install fresh observium instance on new server
6. tune up config.php
7. edit cron 
8. start cron and http server

You can rediscover all devices manually or leave it for observium itself. All graphs and data has been transferred without any problems. If you experience issue with graphs via rrd tool, just make another dump from original database flush data in new database and import them again.

Good luck :)

You can copy all of the graphed data by copying over the rrd directory to the new install.

You can also copy over the MySQL database if you're familiar with MySQL, otherwise you need to add and rediscover all of the devices.

Generally for backup/restore and migration you need mysql database, rrd directory and config.php.

Subject: [Observium] Moving Data to new build

How/Can you move data (graphs, device information etc) from one Observium build to another new build?

 

I have been evaluating a Turnkey Linux CE build of Observium adding some devices etc. We like it and have purchased a license for the PE edition.

 

I’ve been having little success moving the Virtualbox hosted version to ESXi 6.x for production. So I was thinking of installing a new build ontop of Debian 9.

Can I move our Vbox hosted data over or do I just suck it up and start again?

 

Thanks,

Barry
