# Hideez Enterprise Server updates

Depending on how the server was installed, there are different methods for updating:

* [*Update HES on Linux server*](/hideez-enterprise-server/deployment/hes-update/linux.md)*,*
* [*Updating HES on a Linux server installed through the Docker system*](/hideez-enterprise-server/deployment/hes-update/docker.md)*,*
* [*Update HES on a Windows server*](/hideez-enterprise-server/deployment/hes-update/windows.md)*.*

When you upgrade the server, the data is preserved, but it is recommended to back up the database before.
