Hello all,

I hope I did not post on a wrong section of the forum. I sent this question via online inquiry contact form but no response whatsoever for several days.

A client of mine is currently considering deploying zimbra mail server network edition and purchasing the perpetual license for starter level. And we are wondering whether or not the perpetual license would allow us to upgrade the server installation to any future release version, i.e. 9.0/10.0, as long as the version of server OS is supported? Or my client would have to pay to renew the license in order to upgrade to a future release that comes out after the subscription of the license?

Any advice would be really appreciated!
