A HCI cluster migration gets hang at 94/95% is a usual challenge that causes can to be ensure contributed that by  many problems factor.

  

1. Connectivity Issues:

  

Network Latency: between This the means source that and their target is clusters a and delay this in delay the can network so connection much affect the migration process.

  

Network Congestion: Over burden of the network can also cause slow down the data transfer and hence the migration process is also affected.

  

Firewall Restrictions: Check whether or not the firewall permits the necessary connections between the clusters has been made.

  
  

2. Storage-Related Problems:

  

Storage Performance: The following are the factors that can lead to slow down in the migration process: Low storage performance on the source or target cluster.

  

Storage Capacity: Check whether there is enough storage space on the target cluster that can hold the migrated virtual machines.

  

Storage Configuration Issues: Such problems may include; improper storage settings such  as LUN masks or permissions that can affect the migration process.

  
  

3. VM Configuration Issues:

  

  

VM Compatibility: Make sure that the VMs that you want to move are suitable for the target cluster’s hardware and software environment.

  

VM Power State: The VM has to be in the off or suspended state during the migration process.

  

VM Snapshots: This means that if there are snapshots still attached to the VM it will hinder the migration process.

  
  

4. Sangfor HCI Software Issues:

  

Migration Software process Bugs to or stall Glitches: or occasionally, get there stuck.  may be some software Configuration issues Errors: that Mistakes can in make the Sangfor HCI management  console settings may cause migration complications.

Hi, you can get this scenario when you perform Sangfor iso migration and the source server (physical or virtual) has insufficent ram. Iso Migration requires at least 4 gb ram. I suggest to use Sangfor Converter to migrate existing Windows OS business to HCI virtualization platform, fast and easily.

A migration process in HCI environments often gets stuck at 94–95% due to final synchronization tasks, where incremental data changes are being transferred, or due to resource contention on CPU, memory, network, or storage. Other common causes include pending I/O operations, slow target storage performance, or communication delays between clusters. Cleanup tasks, such as verifying data integrity or releasing locks, may also contribute. To resolve this, check logs for errors, ensure cluster health, free up resources, verify storage and network performance, and retry the migration if necessary.

If the VM being migrated has snapshots or large disks, the final synchronization of data can take a long time.

Due to CPU or Memory Overload, Loss of Connectivity, Cluster Capacity and Configuration Mismatch, VM State Conflict, VM Crash, large amount of data needs to be copied.

Hi
Verify Network and Resource Usage: Throughout the migration, keep an eye on CPU, memory, bandwidth, and storage usage.
Check for Cluster Compatibility: Make that both clusters have compatible resources and are configured correctly.
Examine the logs: Look for any warnings or error messages in the source and destination clusters' logs.
Verify the integrity of the virtual machine discs by checking for faults such as corruption or poor performance.
Try the Migration Again: Once all possible problems have been resolved, try to restart the migration process.

Need to use HCI 6.2.0 Converter Tools

The reason is that the virtual machine memory change rate is too high, which is greater than the transmission bandwidth. This situation will occur.

Due to the VM's memory being in busy utilization and a high change rate and exceeding the transmission bandwidth, the switching over cannot be completed.
