Does it work on Zimbra Network edition?

Hi,
we are planning an upgrade from Zimbra 7.2.1 to 8.6 (with licensed Network edition), but we can not upgrade our existing server since its operating system is not supported any more, so we have to install and configure a new server. As far as I understood reading on this forum, ZxMigration and ZxBackup work on Network edition, but on the product brochure ( https://www.zextras.com/brochure/zextras_migrationtool.pdf ) only Open Source edition is mentioned. What is the right answer?
