Quando si tenta di eseguire l'upgrade di Tableau Server, potrebbe verificarsi il seguente errore:
Verification of licensing state failed. (Impossibile eseguire la verifica dello stato delle licenze.)
An error occurred during installation. (Si è verificato un errore durante l'installazione.)
Server must have a valid product key activated to upgrade. If a product key is already activated, make sure the maintenance expiration date has not passed. For steps to obtaining valid product keys for activation, go here https://onlinehelp.tableau.com/current/server/it-it/sug_plan.htm#UpgradeLicense (Per poter eseguire l'aggiornamento, il server deve disporre di un codice prodotto valido. Se un codice prodotto è già attivato, assicurati che la data di scadenza per la manutenzione non sia già trascorsa. Per conoscere i passaggi per procurarti i codici prodotto validi per l'attivazione, visita l'indirizzo https://onlinehelp.tableau.com/current/server/it-it/sug_plan.htm#UpgradeLicense)
