Sometimes when trying to launch my t1.micro EC2 instance, it cannot be provisioned and Amazon recommends trying a different availability zone. Is it possible to change this for an existing instance?

It's not possible to move an existing instance to another subnet, Availability Zone, or VPC. Instead, you can manually migrate the instance by creating a new Amazon Machine Image (AMI) from the source instance. Then, launch a new instance using the new AMI in the desired subnet, Availability Zone, or VPC.
Moving an EC2 Instance to a Different Availability Zone Shutdown / stop the instance. Right-click the instance and select Create Image to make an AMI from the instance. Go to the AMI page, right-click on the new AMI and select Launch Instance. In the new instance settings, choose a specific (different) availability ...
To add an Availability ZoneSelect the check box next to an existing group. A split pane opens up in the bottom of the Auto Scaling groups page. On the Details tab, choose Network, Edit. In Subnets, choose the subnet corresponding to the Availability Zone that you want to add to the Auto Scaling group.
It is not possible to simply change the instance type – you must migrate to a new instance type by creating an image of the existing instance and launching a new instance of the desired type from the image.
You cannot move an existing EC2 instance to a different availability zone directly.
However, the following approach can be used to move an instance to a different availability zone indirectly through a new AMI:
Stop (do not terminate!) the old instance in the old availability zone.
Create an AMI based on the old instance.
Run a new instance of the new AMI in the new availability zone. It will be a fairly exact copy of your old instance.
If you were using an Elastic IP address, re-associate it with the new instance.
Once you have tested the new instance and know that it's working well, terminate the old instance in the old availability zone.
