we recently upgraded our ASA 5510 active/standby cluster from ASA Version 8.3.2 to 8.4.1(11). Unfortenatelly the standby ASA is now crashing a few seconds after the configuration was syncronized from the active ASA.
Also completly disabling HA, bringing the default config to standby ASA again and activating HA afterwards didn`t help. Also tried through the Wizzard provided by ASDM to be sure to have no errors with requirements.
Is there anybody who had same problems ? Or better any idea how to solve this without doing a downgrade back to 8.3.2. ?
If you need any more information give me a hint what excatly you would like to see and I will provide the information.
Did you follow the document for zero-downtime upgrade in HA:
unfortenatlly I didn`t had this document. And I am also not able to access the document. So I can`t check if I did any big mistakes.
