Upgrading from 6.2.2 to 8?

Im currently running pydio 6.2.2 in cPanel through go daddy. While im in pydio it tells me there are updates to be installed when i go to update it in cPanel it says “! The web application selected is already running the latest version.” how can i update my pydio i think this old version im running is giving me issues with people download form public links on a Mac

there could you tell me how you installed Pydio,
as for the upgrading could you try to update your packages on your server and retry the upgrade process.
