# Installation

Use the Novacura Flow server management tool to do a new Flow server installation, upgrade and apply service packs.\
 The difference between an upgrade and a service pack is that an upgrade is between a minor version like 6.2 to 6.3 and a service pack is always within the minor release like 6.2.3 and 6.2.7.

#### Upgrade <a href="#upgrade" id="upgrade"></a>

An upgrade includes new features and corrections and can change the structure of the Flow database. All Flow clients need to be updated to the same version as the Flow server.

#### Service pack <a href="#service-pack" id="service-pack"></a>

&#x20;A service pack only includes corrections that are suitable for patching. A patch will for example not change the database structure of the internal Flow database.
