Is there some formal documentation available regarding the new license activation scheme, fingerprinting, and how it operates in the context of multiple server installations? e.g. an installation with several MTA/LDAP/mailbox servers, and a failover server? Or an installation with a single live production server and a cold failover/DR server, so on. Support wrote "Once you activate a license on one node (production node), it cannot be activated again on a cold standby." but I am dubious.
What can lead to a need for a new activation? I presume that upgrades will preserve license activation. Will installing additional nodes after initial activation lead to activation issues (adding MTAs, mailbox nodes, LDAP nodes, changing LDAP master, so on)?
