Upgrade to centos 7

[sharding]

I was having a discussion thread about upgrading and it's locked, so had to start a new one

last advice was "I personally wouldn't recommend upgrading it, I would setup a new CentOS 7 server and then install the same version of XI on the new system the run the backup_xi.sh on the old server and then run the restore on the new server. That would get you up and running with the best chances for success.

You can follow this guide here:

So first question, sizing, any guidelines for sizing of my new VM ?

second part to this it the back and restore mentioned in the best last advice, does this do all the scripts and permissions ? we have custom checks and scripts and would I have to do any customer cron jobs separate ?

So first question, sizing, any guidelines for sizing of my new VM ?

It would depend on your environment. Here's our general guidelines on the hardware requirements:

What is the size of your VM at the moment? How many nodes are you monitoring? Are you planning adding many new hosts/services? Have you ever ran out of disk space or got close to running out of disk space on the old system? Storage is not so expensive, so it's better to be safe, and have more of it than "just right" or not enough.

Code: Select all

second part to this it the back and restore mentioned in the best last advice, does this do all the scripts and permissions ? we have custom checks and scripts and would I have to do any customer cron jobs separate ?

All scripts in the nagios directory/sub-directories will be backed up and restored. However, you may need to re-add your custom cron jobs manually.

great thanks - we already at those listed max hosts, services, and only going to nearly double very shortly and just grow exponentially from here on out,

I'll stick to our standard config, useful for cpu and ram though, vmware world everything is easy.
