Zenoss - how to transfer data to another server?

Question

linux

Actually, there is a Zenoss 2.5.2 server.
I decided to raise zenoss 3.5 on a new piece of hardware
Question - how can I transfer all devices, as well as event from the old server to the new one?
Infa is rather poor on zenoss. English is a bit of a problem.

Answer 1

Briefly, the migration process can be broken down into 3 stages. The first is the Organizers-Devices tree. Out of the box there are zenbackup utilities that export to xml. But it is not known how this will pass between different versions. If there are few objects, then you can use handles through zendmd, or even automate this process.
The second part is RRD files with metrics from /opt/zenoss/perf. They can either be copied or also overtaken via xml using rrdtool.
The third part - events, are stored in MySQL. I have not seen any proven solution, you may have to manage it manually.

Answer 2

on current fedora OS server
on new debian . Perhaps some troubles due to different OS versions?
1. Organizers-Devices Where is the device data?
As I understand it, to run zenbackup utilities, etc. is it necessary to stop zenoss-a itself?
How to upload from xml to a new server?
2. I found RRD files in the /usr/local/zenoss/perf/devices
directory, there are rrd files. As I understand it, they display graphs. not the device data itself.
3. Where exactly are Events stored?
