Requirements and OS Support
Adobe Flash Player End of Life
4.10 new features
Cloud Console integration
V4.10 integrates with the GCP Console to allow seamless deployment of the migration manager along with creation of required service accounts.
Deployment into private access environment
V4.10 introduces support for deployment into environments with API private access enabled. In these environments the system will be deployed without public IP and will rely on private access to access cloud APIs. See Configuring the migration manager.
Optional deployment of vCenter plugin
V4.10 introduces the option to deploy into an on-prem source vCenter environment with or without deploying the vCenter plugin. Deploying without vCenter plugin allows you to connect multiple Migrate systems to the same vCenter environment. See Registering the VMware vCenter environment.
Support pre/post custom script when upgrading windows 2008 to 2012
V4.10 introduces support for running pre/post custom scripts when using the Windows upgrade. You can add custom scripts to the VM. See Upgrading Windows Server VMs for more.
Support migrating Azure Gen2 instances to Compute Engine
V4.10 introduces support for migration from Azure Gen2 instance to Compute Engine instance with UEFI support.
Automatic O/S discovery and license assignment
V4.10 introduces automatic identification of migrated OS which will, by default, assign the correct license to the migrated VM. In scenarios where you wish to migrate VMs using Windows BYOL license or Linux premium license you will need to provide these as inputs in the Runbook. Please see the licensing section in the documentation.
Fixed an issue with Windows partition detection for certain volume structures.
Support added for Azure disks over 4 TB.
Fixed an issue with AWS ena drivers causing Windows images to crash after migration.
#160405343: Due to a change in behavior on the activation flow for SUSE, configuring repositories on SUSE Enterprise Linux instances post-detach now fail.
Workaround: The following workaround can be used prior to detach (either before migration or before detach).
- Follow the instructions described for Situation 4 at https://www.suse.com/support/kb/doc/?id=000019633 to download the required packages for Compute Engine as a tar.gz file.
For SLES 12.x, then run the following commands:
tar -xf late_instance_offline_update_gce_SLE12.tar.gz
zypper --no-refresh --no-remote --non-interactive in *.rpm
For SLES 15.x, then run the following commands:
tar -xf late_instance_offline_update_gce_SLE15.tar.gz
zypper --no-refresh --no-remote --non-interactive in *.rpm
#149004085: Ubuntu 14 from on-premise may fail to start networking post detach.
Workaround: Connect via the serial console and manually add the network interface with DHCP.
#145086776: In rare cases, older versions of RHEL7 may stop responding during streaming or reach a Kernel panic. This issues were resolved in later versions of RHEL7.
sudo yum update before
migrating to update the system.
#145644737: Clones created on Azure or AWS from instances of Linux distributions that use cloud-init may experience issues in booting after installing the Linux prep package.
Workaround: Uninstall the package before cloning and reinstall when preparing to migrate.
#143313211: Customer migrating RHEL 6.8 VM may experience boot issues in the cloud destination.
RHEL 6.x systems using kernel versions 2.6.32-xxx and using LVM may reach a kernel panic when booting in Compute Engine during migration.
Workaround: The kernel should be upgraded to 2.6.32-754 or higher before migrating.
#143262721: Migration of VM from Azure fails when data disk is greater than 4 terabytes.
At this time, Migrate for Compute Engine does not support migration of Azure VMs with data disks bigger than 4TB.
Workaround: Make sure VM has data disk smaller than 4TB.
#131532690: Run-in-cloud and migration operations may fail for Windows Server 2016 workload when Symantec Endpoint Protection (SEP) is installed. This may also happen when SEP appears to be disabled.
Workaround: Modify workload Network interface bindings to remove the SEP option.
- Download Microsoft Network VSP Bind (nvspbind)
- Install Microsoft_Nvspbind_package.EXE into c:\temp.
- Open a command prompt as an Administrator and run the following:
nvspbind.exe /d * symc_teefer2
#131614405: When the Velostrata Prep RPM is installed on SUSE Linux Enterprise Server 11, the VM obtains a DHCP IP address in addition to an existing static IP configuration. This issue occurs when the VM is started on-premises in a subnet that is enabled with DHCP services.
Note: The issue does not occur when the subnet has no DHCP services. There is no connectivity impact for communications with the original static IP address.
#131637800: After registering the Velostrata plug-in, running the Cloud Extension wizard might generate an error "XXXXXXXXXX" upon "Finish".
Workaround: Un-register the Velostrata plug-in and restart the vSphere Web client service, then re-register the plug-in. Contact support if the issue persists.
#131548730: In some cases, when a VM is moved to Run-in-Cloud while a 3rd party VM-level backup solution holds a temporary snapshot, the Migrate for Compute Engine periodic write-back operations will not complete even after the backup solution deletes the temporary snapshot. The uncommitted writes counter on the VM will show an increasing size and no consistency checkpoint will be created on-premises.
Workaround: Select the Run On-Premises action for the VM and wait for the task to complete, which will commit all pending writes. Then select the Run-in-Cloud action again. Note that committing many pending writes may take a while. Do not use the Force option as this will result in the loss of the uncommitted writes.
#131605387: vCenter reboot causes Velostrata tasks in vCenter to disappear from UI. This is a vCenter limitation.
Workaround: Use the Velostrata PowerShell module to monitor Velostrata managed VMs or Cloud Extensions tasks that are currently running.
#131638716: With an ESXi host in maintenance mode, if a VM is moved to cloud, the operation will fail and get stuck in the rollback phase.
Workaround: Manually cancel the Run-in-Cloud task, migrate the VM to another ESXi host in the cluster and retry the Run-in-Cloud operation.
#131638455: A Run-in-Cloud operation fails with the error - "Failed to create virtual machine snapshot. The attempted operation cannot be performed in the current state (Powered off)".
Workaround: The VMware VM snapshot file may be pointing to a non-existent snapshot. Contact support for assistance in correcting the issue.
#131534862: In rare cases, after running a Workload back on-premises - Workload VMDK's are locked. In certain cases, this is due to network disruptions between the Velostrata management appliance and the ESXi host on which the workload is running.
Note: The issue will resolve itself after 1-2 hours.
#131550214: During Detach, the operation might fail with the following error message: "Operation was canceled".
Workaround: Retry the Detach operation.
#131650367: When performing a detach after a cancel detach operation, the action may fail.
Workaround: Retry the operation.
#131649978: In the event of certain system failures, Velostrata components disconnect from vCenter. In this case, an event may not be sent, resulting in the alarm either not being set properly or not being cleared properly.
Workaround: Clear the alarm manually in vCenter.
#131532549: For workloads with a Windows machine using a retail license, when returning from the cloud, the license is not present.
Workaround: Reinstall the license.
#131555885: vCenter "Export OVA" operation is available when the VM in cloud is running in cache mode, however, this operation results in a corrupted OVA.
Workaround: Only create OVA after the detach.
#131647857: In rare cases, when a cloud component instance is created and system fails before it is tagged, the instance will remain untagged. This will not allow full clean-up or repair of the CE.
Workaround: Manually tag the instance, and then run "Repair".
#131537125: Cloud Extension high availability does not work for workloads running Ubuntu OS with LVM configuration.
Workaround: Update the kernel to 3.13.0-161 or higher.
#131560126: Suse12: Due to a bug in SUSE kernel older than 4.2, configurations that include BTRFS mounts with subvolumes are not supported.
Workaround: Upgrade to SUSE version with Kernel >=4.2 (SP2).
#131533480: When using the Create Cloud Extension wizard, using an illegal HTTP proxy address will not generate a warning message.
Workaround: Delete the CE and then create the CE with a valid HTTP proxy address.
#131647654: Run on-premises operation succeeded but the status is marked as failed with error "Failed to consolidate snapshots"
Workaround: Consolidate snapshots via vCenter, and clear the error manually.
#131558198: PowerShell client for cloud to cloud Runbook reports errors when running on PowerShell 3.0
Workaround: Upgrade to PowerShell 4.0
#131533056: When migrating RHEL 7.4 from AWS to Google Cloud, Google Cloud agent will not be installed automatically.
Workaround: Manually remove the AWS agent and install Google Cloud agent
#131532713: After Offline Migration of Windows 2003R2, if a NIC is manually deleted, it may be impossible to auto-detect and automatically reinstall it.
Workaround: The VM storage can be attached to a different VM, and the NIC Registry entry could be imported manually using a similar VM as a reference. Contact support for assistance.
#131532666: Linux versions running with kernel version 2.6.32 may experience a kernel panic on ephemeral storage access failures; these are more likely while streaming over iSCSI.
Workaround: Upgrade your kernel. The issue will also reduce in likelihood after Detach.
#131532846: Certain firewalls and anti-viruses may cause Windows VMs to fail when moved to cloud by blocking iSCSI traffic.
Workaround: Disable the affecting service while migrating and reinstall after Detach.
#131532882: In certain cases, initiating Run in Cloud during a Windows update may cause the update to terminate abruptly and cause a failure to boot in the cloud.
Workaround: Allow the system to finish Windows update and/or suspend Windows updates before migrating.
#135664281: When completing or canceling Azure to Google Cloud migration, if Velostrata Management failed to start the importer, Velostrata-created resources may be left in the original instance's resource group.
#133137658: Scenario: No network connection between Migration Manager and VSphere
Customer Impact: RunInCloud task will stay stuck due to failure in call to getReadSessions on VSphere.
Workaround: Fix the network connection. If not, cancel the task and try again.
#135573857 Scenario: When moving a VM back on-prem with "force" flag, failure to consolidate snapshot will cause the VM to remain as managed by Velostrata. RunInCloud on the same VM may fail since it is not allowed on managed VMs.
Workaround: Wait a couple of minutes and try again.
#137082702: In rare cases, the Cancel detach operation succeeds but the VM instance will fail to start.
Workaround: Move the instance back and move it again to the cloud.
