Refer to the chart again - the row for 3.9
Upgrade to Moodle 3.9.25 is that your current version?
PHP min/max
Also look at 8.0 max in chart - shows only 3.11 and 4.0
So if I am correct, with 8.0 of PHP, you must upgrade from 3.9 to at least 3.11.
Questions:
does your new hosting have a Terminal icon in cPanel?
and does your new hosing have a Git icon in cPanel?
If both of those are true, we need to talk via PM or direct email!
