Hi all,
I have a running Master-Slave MySQL 5.5 servers today - running on VERY high tense.
Running on Debian 6.0 64bit.
In parallel of checking on ways to optimize my code, I want to fresh up the hardware as well.
I have now a 2 new fresh servers (Dual x8 cores + 64GB ram + SSD RAID 1 and Dual x6 cores + 32GB ram + SSD RAID 1) . with Debian 8.0 64bit + Percona 5.6 .
Can you recommend on the BEST smooth way to upgrade from old setup to new setup with minimal impact on the production ?
mysqldump and restore is too slow for me
Thought maybe add both as slaves to the old setup , and somehow , in a blink of an eye, they become a master - slave , and drop the others.
Appreciate your help !
