A major pitfall in this stage is to use the AWS Console to create the resources and deployments on the cloud. This may be very tempting - because of the intuitive UI and the helpful tips that the UI provides. But this can land us in deep mess. It is almost certain that we will not be able to replicate such a deployment without any error. We always live with the risk that the tested application will not work on the production setup. So it is very important to have a CloudFormation or a Terraform script ready to run on test or production environments. As secret for those who are in a mess with this - AWS CloudFormation now lets us create a template out of resources that we built using the UI console. But it is best not to depend upon such saviors, and get into the habit of using Infrastructure as Code.
A friend once told me about his experience with a migration. They had migrated most of it, but were stuck on a few web applications. They had a mean stack that they wanted to run on an Elastic Beanstalk. They struggled with it till a few days before the deployment - only to discover that MongoDB does not go well on an EBS! Since it was AWS, it did not take them time to spin off an independent Document DB instance and get the whole thing working in a day. But such problems are better identified in a POC rather than a day before the go live.
Use the Code Commit. Switch over to the Native AWS CI/CD services like Code Pipeline, Code Build and Code Deploy. This should be a part of the POC and the migration checklist. Any application migration is marked complete only after the pipeline is setup in AWS. People often miss this step when the migrating to the cloud. Then they have to struggle with transporting the binaries built on the premise. Don't waste an EC2 instance only for Jenkins. These services have a very small learning curve, and should be learnt and put into practice from the first day.
