I am relatively new to DBA work and have a critical task in front of me, I really appreciate any detailed help you could offer. What I have a is a roughly 340 GB MySQL database on a Windows server.
I need to migrate it to a new windows server environment (better hardware, ram etc). MySQL is currently 5.0 and I need/want to also upgrade MySQL to something like 5.5-5.7 as well. I feel like with a DB that large MySQLdump is out of the question? I don't know what other way to migrate over to new hardware though other than maybe some kind of directory copy? But that might have hidden issues of its own particularly with a version upgrade in the plan (replication issues etc). The engine type is mixed but primarily innoDB. I would love to be able to optimize/repair the db as I am doing this via the mysqldump but that can be done later independently of course.
Can anyone help with a quasi step by step solution to how they might accomplish this? Downtime is NOT an issue as long as it doesn't exceed say 10 hours. I will be setting up replication to a linux box to avoid this issue in the future and allow me to use some percona tools (they told me they can't help with windows though) I really appreciate your time and guidance!
