### EcoStruxure Web Services (EWS) configurations

By default, the EWS service is disabled in PME 8.2.

If EWS is configured on the 7.2.2 old system, it must be re-enabled in the new 8.2 system.

To check for EWS customization on the old system:

1. In Windows Explorer navigate to `…\Schneider Electric\Power Monitoring Expert\Applications\EWS\` and then open `Web.config`.
2. Search for the following string:

- `EWSEnabled`

- If the `EWSEnabled` value is `1`, then EWS is configured. If the value is `0`, then it has not been enabled and does need to be updated in the new system.

3. If EWS is enabled, search for the following settings:
   - `EWSAlarmSortOrder`
   - `ContainerItemStructure`
   - `DisplayNanValue` `NaNValue`
   - `ConcatSourceAlarmEventId`
   - `RealTimeRefreshRate`
   - `RefreshImmediately`
   - `RealTimeSessions`
   - `IgnoreCurrentCulture`
4. Note the setting values; you will need to copy these to the EWS configuration on new system.

To transfer any custom EWS device type definitions:

1. In Windows Explorer navigate to `...\Schneider Electric\Power Monitoring Expert\system\WebServices\Extensions\`.
2. Copy the Extensions folder to `...\SBS Upgrade Package\EWS`.
