Summary

Revises the 64-bit operating system prerequisite to state the agent supports x86_64 and arm64 Linux on Amazon EC2, and does not support 32-bit systems or Windows on arm64.

Security assessment

This is a compatibility prerequisite update describing supported architectures; it carries no direct security impact.

Evidence

  * **64-bit operating system** — The AWS Replication Agent supports `x86_64` source servers and `arm64` Linux source servers that run on Amazon EC2. It does not support 32-bit systems or Windows on `arm64`.
