Re: How to upgrade from 5.1.56 to latest version 8.x
You need to step through the latest intervening versions, 5.1 -> 5.5 -> 5.6 -> 5.7 -> 8.0.
Yoiu'll need to read
https://dev.mysql.com/doc/refman/8.0/en/backup-and-recovery.html
The safest (but slowest) method is logical eg via mysqldump.
At each stage you'll then need to run mysql_upgrade against the dbs, and catch & fix compatibility errors.
