right procedures for clear and re install nagios xi

[mmhamdan]

Hello everyone, Hope you are doing great

guys I'm running Nagios XI 5.4.4 we were having many hosts on it and we want to clear everything and re install it . My questions are

*dose default restore script is enough

* if i removed Nagios and my maintains license was expired then re install it would it work

*is there any script other than default restore that could help me with rebuilding new Nagios system

Hello, @mmhamdan.
The restore_defaults script will delete all hosts and services from the database and leave only the localhost entries. However, if you want to delete absolutely everything, including performance graphs, backups, and other temporary files then I'd probably go with the uninstall script:

No, the license key is dependant on a timestamp. So if it was expired it will never work.
