Eu deveria ter visto isso a quilômetros de distância ...
Eu descompactei o arquivo de backup e editei o arquivo archive.xml removendo a linha com os "customFields" inseridos. Problema resolvido.
Fonte: Server 2012 R2 Destino: Servidor 2012
Este é o comando que eu uso para exportar:
C:\Program Files\IIS\Microsoft Web Deploy V3>msdeploy -verb:sync -source:apphos
tconfig="mywebsite" -dest:package=c:\test.zip,encryptPassword=password -skip:Directory= -skip:File=
O seguinte é o erro que recebo no IIS ao tentar uma importação:
Microsoft.Web.Deployment.DeploymentException: Child object 'customFields' cannot be added to object 'logFile'. The 'logFile' provider may not support this deployment. at Microsoft.Web.Deployment.DeploymentObject.AddChild(DeploymentObject source, Int32 position, DeploymentSyncContext syncContext) at Microsoft.Web.Deployment.DeploymentSyncContext.HandleAddChild(DeploymentObject destParent, DeploymentObject sourceObject, Int32 position) at Microsoft.Web.Deployment.DeploymentSyncContext.SyncChildrenOrder(DeploymentObject dest, DeploymentObject source) at Microsoft.Web.Deployment.DeploymentSyncContext.SyncChildrenOrder(DeploymentObject dest, DeploymentObject source) at Microsoft.Web.Deployment.DeploymentSyncContext.SyncChildrenNoOrder(DeploymentObject dest, DeploymentObject source) at Microsoft.Web.Deployment.DeploymentSyncContext.SyncChildrenOrder(DeploymentObject dest, DeploymentObject source) at Microsoft.Web.Deployment.DeploymentSyncContext.ProcessSync(DeploymentObject destinationObject, DeploymentObject sourceObject) at Microsoft.Web.Deployment.DeploymentObject.SyncToInternal(DeploymentObject destObject, DeploymentSyncOptions syncOptions, PayloadTable payloadTable, ContentRootTable contentRootTable, Nullable'1 syncPassId, String syncSessionId) at Microsoft.Web.Deployment.DeploymentObject.SyncTo(DeploymentProviderOptions providerOptions, DeploymentBaseOptions baseOptions, DeploymentSyncOptions syncOptions) at Microsoft.Web.Deployment.UI.InstallProgressWizardPage.OnWorkerDoWork(Object sender, DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)
