Move classic EC2 instance into VPC

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.
2. Click Instances in the navigation pane.
3. On the Instances page, right-click your running instance and select Create Image.
4. Fill in a unique image name and an optional description of the image (up to 255 characters), and click Create Image.
5. Go to the AMIs page and view the AMI's status. While the new AMI is being created, its status is pending.
6. It takes a few minutes for the whole process to finish.
7. Once your new AMI's status is available, go to the Snapshots page and view the new snapshot that was created for the new AMI. Any instance you launch from the new AMI uses this snapshot for its root device volume. You could update your Auto Scaling group with the new AMI, however we will do this as part of the AWS CloudFormation step.

Important information:

1. We have to wait 30 mins after Lauch, for Password configuration.
2. The password is the same as for the instance from which you created the AMI, unless this setting was modified in the EC2Config service settings.
3. You will not use Same IP Address, becuase this IP address is allocated to classic EC2 pool and new instance will require an IP of VPC pool.
4. After migration we will get all the informations same as it was in previous instance.

why migration required?

1. classic EC2 not supported Multiple IPs
2. classic Ec2 in not secured as VPC EC2, as classic Ec2 instance is touch with direct environment.
