Why Is It Not Easy To Migrate From t1.micro to t2.micro?

Normally, we launch a new instance from AMI. This AMI is created from the snapshot which is taken from the existing instance. Thereafter, the migration part is done smoothing.

However, the process is not the same with different virtualization types.

  • T1.micro: Paravirtualization or PV
  • T2.micro: Hardware Virtual Machine or HVM

Therefore, before we begin to the migration steps, here are the prerequisites:

  • You need to be a root user to execute the commands. Use “: sudo su.”
  • Make sure they are in the same availability zone. Mixing the availability zone increases the workload.
