However, moving the bits is only half the battle. Converting a physical server or a VMware VM into a bootable Amazon Machine Image (AMI) requires a complex orchestration of drivers, boot configurations, and OS tweaks.
However as they were about to complete the setup, a strange issue appeared. Their DR site could not properly communicate back to their primary site due to some network configurations being converted during the replication process. E-Shop engineers spent hours trying to troubleshoot the issue but could not pinpoint the cause.
The is the unsung hero of the migration journey. It takes the raw, dirty data from your data center and scrubs it until it’s ready for the cloud. awsreplicationpostconvertservice
The E-Shop team was grateful for John's help and expertise in resolving the issue. They realized that the "awsreplicationpostconvertservice" was a powerful tool that could simplify their disaster recovery setup, but it required careful configuration and monitoring to ensure smooth operation.
By understanding that this service exists to bridge the hardware gap between on-prem and AWS, engineers can better diagnose failures. The next time a launch fails in the "Converting" phase, check your drivers, verify your KMS permissions, and look closely at the boot configuration. However, moving the bits is only half the battle
The E-Shop team was thrilled to learn about this service and quickly set it up. They configured the service to replicate their data from their primary site to their secondary site. The service worked its magic, and soon their secondary site was up and running with almost identical configurations and data as their primary site.
When you replicate a server to AWS, the source server is streaming block-level data to a staging area in your target AWS account. This staging area is usually an EBS volume attached to a "Replication Server." However, a raw copy of a disk from an on-premises environment won’t boot in AWS. It lacks the necessary drivers (like AWS ENA, NVMe) and the correct boot configuration (GRUB/BCD). Their DR site could not properly communicate back
While AWS handles the automation, "Post-Convert" failures are a common pain point during migrations. If your launch fails, it usually happens during the conversion phase. Here are the top three reasons why:
It runs automated scripts after the server has been converted from its original source format to an AWS-compatible format.
Use PowerShell to confirm the main replication agent is active: Get-Service | Where-Object Name -like "*AWSR*" .
Data replication requires an open connection over TCP port 1500 between your source server and the Staging Area in AWS.
