So EOL10154 was released however under replacement part number it only says "See the Product Migration Options section below for detailed information on replacing this product" Then under Migration Options it shows basically nothing. Whats the deal?
There is still a 5525-X with SSD available. But as it's now bundled with FirePOWER, the oder-code has changed. There are different options, one actual Code is now ASA5525-FPWR-BUN.
So can I put the same software package that now comes with ASA5525-FPWR-BUN on an ASA5525 previously purchased under the ASA5525-SSD120-K9 partnumber?
Yes, you have to uninstall the old software-module and then you can install the new module.
And remember that you also need a FireSight management server.
