A dump is SQL generated for a particular server and tool version. Capture the first restore error, identify the statement that caused it, and fix the compatibility issue instead of repeatedly importing the whole file blindly.
Record the tool and server versions
SELECT VERSION() AS ServerVersion, @@version_comment AS Distribution;
SHOW VARIABLES LIKE 'sql_mode';
SHOW VARIABLES LIKE 'lower_case_table_names';
SHOW CHARACTER SET;
SHOW COLLATION;Restore methodically
- Use a dump tool compatible with the source server.
- Restore into an empty test database first.
- Check unknown collations and unsupported syntax.
- Review DEFINER clauses, routines, triggers, and events.
- Compare row counts and application queries after import.
