A quick blog post on a fix I found to resolve a replication issue between Hyper-V guest and Azure Migrate with error code 8079002c
Using Azure Migrate and attempting to replicate an On-Premise Hyper-V guest (Server 2012R2) to azure, error code 8079002c kept appearing and the initial replication kept failing.
I will include snippets of the event viewer:-
Application and Services Logs -> MicrosoftAzureRecoveryServices -> replication
Errors found
The configuration file for virtual machine 'SmartHotelWeb1' could not be sent to the Azure Site Recovery. You may not be able to failover back your virtual machine on your host if it gets deleted from the host.

On the hyper-V host I did notice some stale checkpoints from the inital deployment of the Virtual Machine in Hyper-V – I took these during various installs, similar to the below.

The fix
- Stop replication in Azure Portal of affected Virtual Machine

2. This will disable and remove replication menu from affected Virtual Machine in Hyper-V
3. Remove all checkpoints from the Virtual Machine as shown above in Hyper-V
4. Enable replication again in Azure Migrate of affected Virtual Machine, this should enable replication correctly without errors and replication will start shortly after
