Nagios Support Forum

Hi Team,
Our NagiosXI is hosted on centOS 6.5 which will be retiring next year, I wanted to confirm if OS is upgraded to latest CentOS 8 or may be 7 then what differences will occur to NagiosXI and what major issues I might come across?
database? scripts? directories etc
is it doable smoothly without any issues?

Cheers

It is doable to CentOS 7, CentOS 8 is not supported yet.

The instructions are here

Because you are changing OS, the plugins will not be copied because compiled plugins will need to be compiled on the new OS, if you have any custom plugins, these would need to be moved to the new system manually.
