Upgrading Firmware for a USG60 from V4.15(AAKY.2) to 4.70(AAKY.0)

I wish to upgrade a long neglected USG60 to last fw released v. 4.70 (AAKY.0)
Logging into the dashboard, I see the current FW is V4.15(AAKY.2).
I'm wondering if I can upgrade directly to v. 4.65 (the oldest listed in library) and then to 4.70, or I need one (or more) previous firmware(s).In case, where can I find them?

    Hello and Welcome to our Community!

    You cannot directly upgrade from 4.15 to 4.70.
    In this case, you can read our knowledgebase article here.
    The older Firmware downloads are to be found here.

    I hope that this helps.
