Can ASA5500 and ASA5500-X be paired as active standby?

Hi, looking at several migration scenarios at a customer, is it possible to have a 5512-X as primary firewall, with a 5510 as secondary in an active standby cluster (running the same license type)?

Thanks!

Hi,

No, you cannot pair ASA firewall that are of different model

Hardware Requirements

The two units in a failover configuration must be the same model, have  the same number and types of interfaces, the same SSMs installed (if  any), and the same RAM installed.

If you are using units with different flash memory sizes in your  failover configuration, make sure the unit with the smaller flash memory  has enough space to accommodate the software image files and the  configuration files. If it does not, configuration synchronization from  the unit with the larger flash memory to the unit with the smaller flash  memory will fail.

Hi

No. Both members of a cluster must be identical hardware wise.
