Esportare gli argomenti creati in Viva Engage con PowerShell
Con PowerShell è possibile esportare gli argomenti creati in Viva Engage (noti anche come Lite Topics) in un file .csv. Sono inclusi gli argomenti creati prima di abilitare l'integrazione con Viva Engage.
Nota
Questo articolo presuppone che si abbia familiarità con l'uso di PowerShell.
Requisiti
Per esportare gli argomenti, eseguire uno script di PowerShell. I requisiti per eseguire lo script sono:
- PowerShell 7 o versione successiva. Per installare la versione più recente di PowerShell, passare a Installazione di PowerShell in Windows.
- L'utente che esegue lo script deve essere un amministratore di Topics o Knowledge Manager.
I file di supporto chiave sono inclusi in questo documento:
Eseguire lo script di PowerShell
- Ottenere lo script.
- Usare i parametri seguenti:
Export-TopicLite -Upn < string > | Export-Csv -Path < string >
Esempio:
Export-TopicLite -Upn "user@domain.com" -Path "C:\"
Output
Il file .csv include l'output seguente:
- Nome dell'argomento
- Tipo di argomento
- Stato ciclo di vita
- Ora ultima modifica
