Need to Migrate ECS-Sync on AWS

We currently have the software installed on an on-premises server, and our objective is to migrate it to AWS.

I'm new to ECS-Sync and would appreciate some guidance on how to proceed with the migration. I have a few specific questions:

1. I came across some scripts in the repository, but I couldn’t find any reference or download link for the ecs-sync-centos.ova file. Is there a pre-built OVA available for download? If so, where can I find it?

2. Does ECS-Sync require any kind of license to run, or is it fully open-source?

3. Are there any official installation or migration guides specifically for deploying ECS-Sync on AWS?

4. If we migrate the deployment to AWS, do we need to notify the support team regarding changes in IP/MAC addresses?

Our main requirement right now is to obtain the pre-built OVA file. If anyone can help with that, it would be greatly appreciated. Thanks in advance!
