If you have Central, you can upgrade to AOS10 with Central. If you want to stay on the same architecture, you could check the WLAN platform compatibility matrix, from there you can see the 7005 can go up to 8.13; the AP-305 also seems supported on 8.13. The 8.13.1.1 appears latest version at the moment.
Please make sure you have a valid support contract, and work with your HPE Networking partner for guidance/advise what would be the optimal version in your situation.
