migrate to new server error mysql

Hi,
i try to migrate my old vps (centos 6) to new vps (centos 7), but i can do this…

i follow the instruction on
https://www.virtualmin.com/documentation/system/migrate

but when i restore on new vps with command
virtualmin restore-domain --source /root/backups/ --all-domains --all-features

i receive this error
Re-loading MySQL database aaaaaa …
… load failed! ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘mysqldump: Couldn’t execute ‘SHOW FUNCTION STATUS WHERE Db = ‘aaaaaaa’’: Cannot l’ at line 1

but on my old vps there is MySQL version 5.5.49
on new vps MySQL version 5.5.52
see that on webmin -> servers -> MySQL Database Server

i try also --continue-on-error
i see all virtual server but all database is empty…

how cloud i resolve?

thank you in advance

Alessandro
