How often should we upgrade MySQL version
We are running MySQL 5.1.46 with master to master replication with 3 other servers for 3 different websites in 3 different parts of the world. My question is how often should we be looking to upgrade our MySQL version considering we can't really afford any downtime.

RE: How often should we upgrade MySQL version
Ever heard the old saying, If it ain't broke, don't fix it. ;-) I'd say that as a general rule: 1. if you aren't experiencing problems then don't upgrade. 2. if you aren't subject to any vulnerabilities that may be found, then don't upgrade 3. if you don't need a new feature introduced, then don't upgrade 4. if you need to be up 100%, then don't upgrade Having said that, it is possible to upgrade with minimal downtime if you're smart about it. Get another server (or two or three) that is a clone of the existing ones. Upgrade those. Test those. Swap over. Then for the next release, do the same thing with the servers you now have as the spares. If you're in such a mission critical situation, you should have spare servers and live hot-swapable backups anyways right. -Original Message- From: Neil Tompkins [mailto:neil.tompk...@googlemail.com] Sent: Friday, November 18, 2011 11:54 AM To: MySQL ML Subject: How often should we upgrade MySQL version We are running MySQL 5.1.46 with master to master replication with 3 other servers for 3 different websites in 3 different parts of the world.
