升级到 Amazon RDS 多可用区是否会中断正在运行的实例的 I/O 操作？
如果我将单可用区 RDS 实例升级到多可用区实例，是否会像通常拍摄数据库快照一样中断当前实例的 I/O 操作？或者，当第二个多可用数据库实例已配置并上线时，我当前的实例是否会继续正常运行，而不会对我的应用程序造成影响？
我确实意识到从小到大的升级确实会影响 i/o 操作几分钟。这只是使用现在在网络上提供的漂亮的 GUI 工具在不同的 az 中创建一个具有相同大小/配置的新实例。
我无法在亚马逊文档中找到答案，并希望堆栈上的人有这里的经验。
谢谢！
If I upgrade a single-az RDS instance to a multi-az instance, will that interrupt the i/o operations of my current instance in the same way that taking a database snapshot normally would? Or, will my current instance continue to run as normal, with no impact to my app, while the second multi-az db instance was provisioned and brought online?
I do realize upgrading from small to large does impact i/o operations for a few minutes. This would simply be bringing up a new instance of the same size/configuration in a different az, using their nice GUI tools now available on the web.
I was unable to locate an answer in the Amazon docs, and was hoping someone on stack has experience here.
Thanks!
