How to attach EBS volume from original EC2 instance to a new EC2 instance?
currently my website is running under a t3a.small EC2 instance (Origin - N California) and the volume size is 10 GIB. Now i have launched a new EC2 t2.micro instance (Origin - Mumbai) and the volume size is 8 GIB. All i'm doing for avoiding charges as i am a free tier user and the original instance is not cover the free tier promotion. So how can i attach EBS volume from original instance to new instance without losing any data?
If you shut the original instance down (not terminate!) then the EBS volume will no longer be attached to an instance; you can attach it to your new instance then.
However: That will give you two volumes; a "new" root volume and the original root volume attached to a different mount point/drive letter.
Note that in some circumstances it will be possible just to change the instance type and boot on the original root volume: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-resize.html
