cisco asa 5510 IOS upgradation

Hi All ,

Greetings of the day!!!

I have to upgrade my cisco ASA  IOS from 8.2.3 to 8.4.4(1).

Could i upgrade the ios directly from 8.2.3 to 8.4.4(1) OR

I Should go step by step means 8.2.3 to 8.2.4 to 8.2.5 to 8.3.1 to 8.3.2 to 8.4.1 to 8.4.2 to 8.4.3 to 8.4.4 to 8.4.4(1).

 

Also my current asdm version is 6.3.3 and as per compatibility matrix of ios and asdm I have upgrade it with 6.4.9 or later.

Please suggest that can i directly upgrade the asdm version  from 6.3.3 to 6.4.9 .

 

Also please suggest after the upgradation of ios and asdm software there will be any change in old configuration or the configuration will remain unchanged.

also after upgradation is there any requirement to install the feature key again .

 

please suggest.....

 

Thanks & Regards,

Madhuraj
