I've contacted zimbra via e-mail.
I've left a voice message to the main phone number.
I've left a voice message on the sales phone number.
Who doesn't answer their sales number?
No one answers, no one responds to the voice messages.
I have a customer who needs to purchase zimbra network edition V.7, who is using open source V6.
Is there a way to upgrade from V.6 open source to V.7 network edition?
