Terraform version upgrades

Hi Terraform Community.
Kindly help to understand.
I have two different microservices.

  1. microservice has terraform version 0.12.30 and aws provider version 2.70.0
  2. microservice has terraform version 0.13.3 and aws provider version 2.70.0

I would like to understand if the above difference on terraform versions will impact or cause any issues on my infrastructure?
Would like to know best practices regarding the same
