Re: Upgrading MySQL with GTID replication to MySQL 5.7

Hi Sandra,

If you are already using GTID in 5.6 that should not be a problem. You should take a backup (physical or logical) and restore it on a new server. Make this new machine a slave from the original (don't forget to change the server_id). Then upgrade the files to 5.7 (install 5.7) and run mysql_upgrade, restart and now you should have the master in 5.6 and the new slave in 5.7.

You can find more info at https://dev.mysql.com/doc/refman/5.7/en/replication-upgrade.html

Regards,

lefred
