### EcoStruxure Web Services (EWS) configurations

The EcoStruxure Web Services (EWS) service is disabled when PME is initially installed. If EWS was enabled on the old system, it must be manually enabled on the new server and updated with the values from the old system.

To enable EWS, update the EWS settings from the old system, and copy the extensions folder:

1. In Windows Explorer navigate to `…\Schneider Electric\Power Monitoring Expert\Applications\EWS\` and then open `Web.config`.
2. Search for the following string: `key="EWSEnabled"`.
3. Change its value to `1`.
4. Update the following `Web.config` values to be the same that they were on the old system:
   - `EWSAlarmSortOrder`
   - `ContainerItemStructure`
   - `DisplayNanValue` `NaNValue`
   - `ConcatSourceAlarmEventId`
   - `RealTimeRefreshRate`
   - `RefreshImmediately`
   - `RealTimeSessions`
   - `IgnoreCurrentCulture`
5. Copy the files from the old `Extensions` folder – `...\SBS Upgrade Package\EWS` – to the new one: `...\Schneider Electric\Power Monitoring Expert\system\WebServices\Extensions`

   Note: There is already an `Extensions` folder in this location in the new system. Do NOT overwrite files in the target folder in case a file already exists.

6. Open Management Console.
7. Select Tools > System > Update EWS Server.
