I'm trying to upgrade version of Nagios XI with the dedicated procedure but when i run "./update" file, i have a lot of error concerning download of elements on mirror.
It is normal because my nagios server does not have access to internet.
Do you know if it is a problem ?
If it is, do you know a offline method to upgrade nagios ?
Other question : Have I to update version after version or I can update directly to the latest-version (as described in official procedure) ?
If I have to upgarde one by one, i don't know where I can find the intermediate version
Thanks
