Update Legacy application to JsCore

Pre-requisite steps​

To ensure the safest possible outcome please follow these steps when upgrading

  • Set the current orientation on the device to make sure it's saved on the server.
  • Set the current working-hours configuration on the device to make sure it's saved on the server.
  • Clear the cache of the device
  • Wait a few minutes so the device can get back to idle
  • Send the migration custom command
  • Wait until the device updates (it might reboot multiple times)
  • Once the device is updated and came back online, check the preview and make sure everything is fine

Special cases and platform-specific issues​

Brightsign​

  • The GPIO sensoring no longer works without sensor configuration and an ENTERPRISE license.

LG​

  • On devices with WebOS version 4.0 there the webView aspect ratio can get stuck when changing the device rotation back and forth.
    This will cause video and stream players to show with incorrect sizes.
    Only factory resetting the device can fix this issue.

Samsung​

  • On legacy Samsung applications, the device's storage can become full, which prevents it from downloading the application file from the server.
    This may appear as if the command isn't reaching the device.
    In such cases, the only viable solution is to perform a factory reset, followed by installing the latest version of the JSCore application
