# Server upgrade
# Why to upgrade?
Performing upgrade constantly, your server recieves all the system updates, security patches and the latest version of the tracker.
# Important to know before the upgrade:
If you have made any manual changes to the server configuration, for example, changing the default parameters of the services, all changes will be revoked by the upgrade and set to the default settings.
The upgrade doesn't interact with the data in the tracker, doesn't change or delete anything. It will not make any changes to the traffic stats, campaign and stream settings, user interface, and so on.
The upgrade will not influence traffic and campaigns' performance. The only exception tothis is if the server malfunctions while upgrading. This can be caused by an issue with theserver itself or by user-made changes that are incompatible with the tracker.
Do not run any other commands on the server while the upgrade is being performed.
# How to upgrade?
Connect to the server (opens new window) using terminal.
Enter the command:
curl https://keitaro.io/install.sh > run; bash run -rt upgrade
- When the upgrade is finished, you will see a green message
Everything is OK!
