License information in the Primary is copied to the Secondary site when doing
database duplication.
After 28 days, the license(s) expire. To renew the license(s), a connection to the
original Primary site must be reestablished. (After the connection to the Primary
is recovered, if Fail-Over occurs again, the license(s) are once again enabled
for the specified duration based on the software version listed above)
When the Forced Change of the Primary System (Program 50-07-01) is used to
manually force the original Primary System to become one of the Secondary
Systems in a Netlink Network, the license information will still be available.
If a user wants to enter another additional feature license, it must be entered on
the original Primary System.
