So the existing version is uninstalled and installed again - even if the versions are the same.</P> Wed, 19 Oct 2016 13:01:49 GMT guido_deinhamm 2016-10-19T13:01:49Z https://community.dynatrace.com/t5/Open-Q-A/Installing-OneAgent-on-a-linux-host-which-is-already-being/m-p/23976#M306 <P>What happens if i try to install agent on a linux host which is already being monitored. Does it reinstall agent? or the installation process terminates in- between as agent is already installed.</P> <P>i want agent to be installed using a script and also want that script to check before installation if its already installed or not. Will implement same only if your script doesn't have that check ?</P> Thu, 24 Mar 2022 14:17:29 GMT https://community.dynatrace.com/t5/Open-Q-A/Installing-OneAgent-on-a-linux-host-which-is-already-being/m-p/23976#M306 siva_vadivelu 2022-03-24T14:17:29Z https://community.dynatrace.com/t5/Open-Q-A/Installing-OneAgent-on-a-linux-host-which-is-already-being/m-p/23977#M307 <P>If you run the installer on a host where OneAgent is already installed and/or running, it is treated as an update.
