I want to reduce the size of the root volume of a Windows server EC2 instance .
1) Stop the running instance (instance 1)
2) Detach its root EBS device
3) Create new instance with any volume (instance 2)
4) Mount the detached volume to new instance as to be seen as secondary volume
5) Shrink the volume
6) Detach it after shrinking
7) mounting to the instance 1
8)Start the instance 1
Are steps above the frequent ones to be followed to achieve this purpose ? Are there any other methods ?
