Hello @Thadepalli Sai Kumar
Based on the error code you provided, it seems that you are trying to replicate a Windows Server 2008 R2 machine to Azure using Azure Site Recovery and you are encountering error code 547000. This error code usually indicates that there is a network issue preventing replication from occurring. However, you mentioned that you are unable to find any trace related to network. In this case, I would recommend checking the following: 1. Check if the replication target storage account is provisioned correctly and has enough space to accommodate the replicated data. 2. Ensure that the virtual machine is running the latest version of Integration Services. 3. Check if there are any anti-virus software or firewalls that might be blocking Azure Site Recovery. You can learn more about folder exclusions required for Azure Site Recovery in the following link: https://docs.microsoft.com/en-us/azure/site-recovery/vmware-azure-set-up-source#azure-site-recovery-folder-exclusions-from-antivirus-program 4. Verify that the virtual machine is not experiencing high churn rate. If the data change rate (write bytes/sec) on the listed disks of the virtual machine is more than the Azure Site Recovery supported limits for the replication target storage account type, then replication may fail. You can learn more about Azure Site Recovery limits in the following link: https://docs.microsoft.com/en-us/azure/site-recovery/site-recovery-vmware-deployment-planner-analyze-report#azure-site-recovery-limits If none of the above suggestions help, then I would recommend checking the logs for more information on the error.

Let me know if you have any further questions.
