ASA IOS upgrade from 8.0(4) to 9.0.3.ed

I have upgraded many PIX and ASA appliances to newer versions of the IOS.  But they have always been from 6.x or 7.x to 8.x.

Is the procedure to upgrade from an ASA 8.0(4) IOS version to 9.0.3 IOS version any different?

If so, can someone point me to a link on the Cisco website with the CLI procedure?

Thank you,

I thought this sharing below link sum it up and it is not viable (or safe) means to push for this especially from the extracted last point to move to 9.x we need to be 8.3 or 8.4. There are some CLI means shared in the same link too for info

We can upgrade from any version to any other version within the same major and minor version. For example we can go from 8.0(2) directly to 8.0(5)

To upgrade from one minor release to another, we cannot skip a minor release number. For instance, we cannot upgrade from 7.0 to 7.2 directly. We should go from 7.0 to 7.1 and then to 7.2

Upgrading from one major release to the next is possible only from the last *minor* release. For example, to upgrade from 7.x to 8.x, we must be at 7.2 which is the last minor version within the 7.x train. We cannot upgrade from 7.1 to 8.x

To upgrade to 8.3, we must be at 8.2

To upgrade to 9.x, we must be running a 8.3 or 8.4. That is if version 8.4 is available for our platform. For ASA55YY-X series, there is no 8.4, so we must be at 8.6

There is the compatibility matrix to note on the model and corresponding model/IOS version
