Re: The selected file is not a valid Moodle backup file and can't be restored.

I did migrate the Moodle site 3.7 to the new server.
I beleived the problem was in php version in the old server but support didn't respond to me.
I upgrade from 3.7 to 3.9 then 4.1 and every thing go smoothly, when I try to upgrade from 4.1 to 4.5 I had the following error:
mod_scorm
Error writing to database
Debug info: Illegal mix of collations (utf8mb4_general_ci,IMPLICIT) and (utf8mb4_unicode_ci,IMPLICIT) for operation '='

SELECT a.id as attemptid, t.scoid as scoid, e.id as elementid, t.value as value, t.timemodified
FROM mdl_scorm_scoes_track t
JOIN mdl_scorm_element e ON e.element = t.element
JOIN mdl_scorm_attempt a ON (t.userid = a.userid AND t.scormid = a.scormid AND a.attempt = t.attempt)

I did upgrade from 4.1 to 4.2 but when upgrading to 4.3 I got the same error message, any Idea

there weren't problems in resources neither in old server nor the new one
