Upgrade Windows Apps

Consult the following list of scenarios for instructions about upgrading your apps.

  • If your .NET app was previously pushed with the binary_buildback and you are relying on the WebAppServer.exe you must push with the hwc_buildpack:

    $ cf push APP-NAME -s windows2012R2 -b hwc_buildpack

    By passing windows2012R2 with the -s flag, you instruct PCF to run the app in the Windows cell. If you are not pushing your app from its directory, add the -p flag to specify the path to the directory that contains the app.

    An app with the hwc_buildpack should not be pushed with the -c flag.

    If you try to cf restage, your app will fail to restage because you cannot switch to the hwc_buildpack using cf restage.

  • If you have a binary app you must push with the -c flag:

    $ cf push APP-NAME -s windows2012R2 -b binary_buildpack -c PATH-TO-BINARY
  • If your app needs a custom start command and requires the WebAppServer.exe, you must update the start command to reflect the path to hwc.exe, which is provided by the HWC buildpack.
