When upgrading a BIG-IP HA pair directly from version 10.2.x to version 12.1.x, the devices may fail to retain their primary and secondary mirror IP addresses after the upgrade.


The devices will not be performing any mirroring after the upgrade to version 12.1.x as a result of this issue.


This will only occur during a direct upgrade from 10.2.x to 12.1.x. This will not occur, for instance, when upgrading to 12.0.x.


You can work around this issue by either: A) Performing an intermediate upgrade to BIG-IP version 12.0.x first. or B) Manually reconfiguring the mirror IP addresses after the devices have been upgraded to 12.1.x (for more information on how to do so, refer to K13478: Overview of connection and persistence mirroring (11.x - 12.x) https://support.f5.com/csp/article/K13478).
