# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
