    • Beginning with 9.5(1.200), the memory requirement for the AVAv5 was reduced to 1GB. Downgrading the available memory on an ASAv5 from 2 GB to 1 GB is not supported. To run with 1 GB of memory, the ASAv5 VM must be redeployed with version 9.5(1.200) or later. Similarly, if you try to downgrade to a version earlier than 9.5(1.200), you must increase the memory to 2 GB.
