# Prerequisites for existing FSLogix configuration

1. Back up your existing profiles. It is highly unlikely that profile data can be lost or corrupted, but it is best practice to have a valid backup prior to any change in the profile configuration.
2. Turn off the GPO configuration of FSLogix Profile Containers. This step is important because you cannot have both GPO and Parallels RAS management of FSLogix profiles enabled at the same time.
3. Before configuring FSLogix profiles for a server in a RAS Farm, make sure there are no user sessions running on the server. As a suggestion, you can make the transition in a maintenance window out of working hours.
