Before downloading, determine compatibility. Run on the ASA:
show version show failover (if applicable) ASDM version must be compatible with the ASA software version. Refer to the Cisco ASA Compatibility Matrix (generally, ASDM 7.x for ASA 9.8+, ASDM 7.20 for ASA 9.20+).
copy tftp://192.168.1.100/asdm-781.bin disk0:/ Refer to the Cisco ASA Compatibility Matrix (generally,
copy scp://user@tftp-server//path/asdm-781.bin disk0:/
