blocks|key|1167475|text|当我们遇到意外的流量时，我刚刚从中型RDS实例升级到大型实例(很好，对吧？:)。由于我们有一个多可用区实例，我们停机了2-3分钟。在亚马逊的文档中，他们说如果你有一个多可用区实例，停机时间将是短暂的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1167476|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I just did an upgrade from a medium RDS instance to a large when we were hit with unexpected traffic (good, right? :) ). Since we have a multi-AZ instance, we were down for 2-3 minutes. In Amazon's documentation, they say that the downtime will be brief if you have a multi-AZ instance.

blocks|key|1167564|text|对于任何感兴趣的人，我们刚刚修改了一个RDS实例(MySQL，15+GB硬盘，其余标准参数)，将其从微型改为小型。停机时间为5分钟。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1167565|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

For anybody interested, we just modified an RDS instance (MySQL, 15 GB HD, rest of standard parameters) changing it from micro to small. The downtime period was 5 minutes.

blocks|key|1382561|text|我们刚刚完成了从db.m3.large到db.m3.xlarge的升级，其中包含运行SQL+Server+2012的200+of非IOPS数据。停机时间大约为5分钟。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1382562|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

We just did an upgrade from db.m3.large to db.m3.xlarge with 200GB of non-IOPS data running SQL Server 2012. The downtime was roughly 5 minutes.

blocks|key|1167684|text|在多az上，将有故障转移，但在其他情况下，它将是平滑的。这是我最新的数据库实例类型的时间表数据，在配置了多Az的Postgres+9.3上，从r3.4xlarge降级到r3.2xlarge，磁盘容量为3TB+(实际数据仅约800G)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1167685|time+(utc-8)+++++++++++event+Mar+11+10:28+AM+++++++Finished+applying+modification+to+DB+instance+class+Mar+11+10:09+AM+++++++Multi-AZ+instance+failover+completed+Mar+11+10:08+AM+++++++DB+instance+restarted+Mar+11+10:08+AM+++++++Multi-AZ+instance+failover+started|offset|length|style|CODE|1167686|entityMap^0|0|0|7A|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

On multi-az, there will be a failover, but otherwise it will be smooth.
Heres the timeline data from my most recent db instance type downgrade from r3.4xlarge to r3.2xlarge on a Multi-Az configured Postgres 9.3 with 3TB of disk( actual data is only ~800G)

<code>
time (utc-8) event
Mar 11 10:28 AM Finished applying modification to DB instance class
Mar 11 10:09 AM Multi-AZ instance failover completed
Mar 11 10:08 AM DB instance restarted
Mar 11 10:08 AM Multi-AZ instance failover started

blocks|key|1382647|text|对于25G的数据，将MySQL+RDS从db.t2.mall升级到db.t2.medium需要6分钟。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1382648|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Upgrading MySQL RDS from db.t2.small to db.t2.medium for 25G of data took 6 minutes.

blocks|key|1167756|text|是的，它们是可升级的。将RDS实例从SQL+Server+2008升级到SQL+Server+2012，实例大小约为36+GB，分类为db-m1-small，存储空间为200+GB，没有IOPS或多AZ。没有停机，这个过程只需要10分钟。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1167757|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Yes, they're upgradable. Upgraded RDS instance from SQL Server 2008 to SQL Server 2012 for instance size of about 36 GB, class db-m1-small, storage 200 GB and with no IOPS or Multi AZ. There was no downtime, this process barely took 10 minutes.

Will I am able to switch (I mean upgrade or downgrade) Amazon RDS instance on need basis or do I have to create a new afresh and go through migration?

Are Amazon RDS instances upgradable?

SQL Server

数据库

MySQL

我是否可以根据需要切换(我的意思是升级或降级) Amazon RDS实例，或者我是否必须重新创建一个新实例并进行迁移？
