30.2 Configuring Migration of a Workload to Microsoft Azure

When you add or discover a workload, the workload is listed on the Workloads page and the status is set as Not Configured. Before you migrate the workload, you must configure the workload for migration:

  1. Launch the PlateSpin Migrate Web Interface.

  2. If you have not configured a Microsoft Azure Location as a migration target, click Targets > Add Target, and then configure the target Azure cloud platform.

     See Targets.

  3. On the Workloads page, select the workload you want to configure.

  4. Click Configure Migration.

  5. Specify the Initial Transfer Method for replication based on the scope of data you want to transfer from the source to the target:

    • Full Replication: Migrate replicates the full volume from the source to the target.

    • Incremental Replication: Migrate replicates only differences in data from the source to the target, provided the workloads have similar operating system and volume profiles.

      NOTE:PlateSpin Migrate does not support Incremental Replication for the initial replication of data to existing target workloads in Azure Cloud. However, you can schedule Incremental Replications for subsequent replication of data. See Incremental Recurrence in Step 8.

  6. Select an existing Microsoft Azure Location target to which you want to migrate the source workload. 

    To verify availability of Premium Storage for the target location, refer to the Microsoft Azure Products Available by Region.

  7. Click Configure Migration.

  8. Configure the following settings:

    Schedule Settings

    Incremental Recurrence

    Specify the time and pattern when you want to run incremental replications after the first full replication, or start each incremental replication manually.

    The default setting is None. The incremental replications are unscheduled.

    To set or modify the incremental recurrence time and pattern:

    1. Click Edit.

    2. For Begin the recurrence schedule, set the date and time when you want to begin the scheduled incremental replications. You can type the date (dd/mm/yyyy) or click the Calendar icon to select the date. By default, the run time is 12:00:00 a.m. (hh:mm:ss a.m. or p.m.).

    3. For Recurrence run setting, set the pattern to follow for scheduled incremental replications:

      • Daily: The replication takes place on the specified daily intervals or on weekdays every week for a period of 60 days from the time the replication starts.

      • Weekly: The replication takes place at specified intervals for a period of 8 weeks from the time the replication starts.

      • Monthly: The replication takes place at specified intervals for a period of 2 months from the time the replication starts.

    NOTE:

    • Scheduled incremental replications are skipped until the first full replication is complete.

    • Scheduled incremental replications take place for a maximum period of 60 days from the time that the scheduled incremental replication runs begin.

    Full Replication

    Specify when you want the first full replication to run, or start the first full replication manually. The first full replication is a one-time event, but the run is attempted daily as scheduled until the first replication begins and completes successfully.

    The default setting is None. The first full replication is unscheduled.

    NOTE:You must prepare the workload prior to the scheduled time or the manual start.The full replication cannot run unless the target VM exists and the workload preparation is complete. If they are not ready, Migrate skips the scheduled full replication and retries it at the scheduled time on the next day.

    To set or modify the schedule for the first full replication:

    1. Click Edit.

    2. Click Start, then set the date and time when you want to start the first full replication. You can type the date (dd/mm/yyyy) or click the Calendar icon to select the date. By default, the run time is 12:00:00 a.m. (hh:mm:ss a.m. or p.m.).

    Blackout Window

    Specify a replication blackout window that suspends scheduled replication activities for a specified period of time and pattern. For example, suspend replications during peak network utilization hours or to prevent conflicts between VSS-aware software and the PlateSpin VSS block-level data transfer component.

    The default setting is None. No blackout window is scheduled.

    To set or modify a blackout window:

    1. Click Edit.

    2. Specify the start and end time for the blackout period.

      The blackout start and end times are based on the system clock on the PlateSpin Server.

    3. Select Daily, Weekly, or Monthly to enable a blackout window, then set the recurrence pattern.

    Compression Level

    This setting controls whether data is compressed during transmission between the source and target workloads, and the level of data compression applied.See Data Compression.

    Select one of the following options:

    • None: No compression.

    • Fast: Consumes the least CPU resources on the source, but yields a lower compression ratio.

    • Optimal: (Default) Consumes optimal CPU resources on the source and yields an optimal compression ratio. This is the recommended option.

    • Maximum: Consumes the most CPU resources on the source, but yields a higher compression ratio.

    Bandwidth Throttling

    Bandwidth throttling enables you to control the amount of available bandwidth consumed by direct source-to-target communication over the course of a workload migration. Throttling helps to prevent migration traffic from congesting your production network and to reduce the overall load of your PlateSpin Server. You can specify a throughput rate for each migration job.

    Throttling is disabled by default with a Throttling Rate value of Off.

    To throttle replications to a specified rate:

    1. Specify a maximum throughput value in Mbps for data transfer for the workload.

    2. Specify the throttling pattern:

      • Always: Always throttle data transfer for the replications.

      • Custom: Specify the time and days to throttle data transfer for the replications running in that window.

        Throttling time is local to the source workload.

    Migration Settings

    Replication Networks for Source

    Specify one or more network interfaces (NIC or IP address) on the source workload to use for replication traffic that are valid for communications with the replication environment.

    If the network for the NIC you specify is not part of your Azure VPN, ensure that the NIC has a public IP address.

    Services to Stop Before Any Replication

    (For Windows Workloads) We recommend that all the non-VSS compliant services or antivirus are stopped temporarily on the source while the VSS snapshot is being captured on the source. Select the Windows services that you want to be temporarily stopped on the source workload while the VSS snapshot is being captured on the source. These services are restored as soon as the VSS snapshot creation completes.

    Services to Stop for Cutover with Replication

    (For Windows Workloads) Select the Windows services that should be permanently stopped on the source workload for cutover with any replication. The services stopped on the source workload during the replication process are not restored afterwards. This does not apply for Test Cutover.

    Daemons to Stop before Any Replication

    (For Linux Workloads) Select the Linux services that you want to be temporarily stopped on the source workload before replication. These services will be restored back after replication completes.

    Daemons to Stop for Cutover with Replication

    (For Linux Workloads) Select the Linux services that should be permanently stopped on the source workload for Cutover with any Replication. The services stopped on the source workload during the replication process are not restored after Cutover. The stopped services are restored after a Test Cutover.

    Target Workload Settings

    (These settings are applied during the Run Cutover)

    Cloud Instance Size

    Select the cloud instance size appropriate for your workload and the Storage account type for the target platform.

    IMPORTANT:The Cloud Instance Size must be of the same storage type as the target account: Standard Storage or Premium Storage. Otherwise, you receive a validation error. To verify the availability of Premium Storage for the target location, refer to the Microsoft Azure Products Available by Region.

    By default, Migrate selects a cloud instance size that supports the same Storage account type and that most closely matches your source workload for the following components:

    • Total number of cores

    • Amount of memory

    • Number of data disks

    • Number of NICs

    The default instance either meets or exceed the settings for each of these components on the source workload. However, you can choose a smaller instance size based on your requirements:

    • The target VM uses the allowed CPU and memory for the instance size. To reduce the number of CPUs or amount of memory on the target workload:

      1. Select a smaller cloud instance size with fewer CPUs or less memory that best fits your needs.

    • The target VM uses up to the maximum allowed number of data disks for the instance size. To migrate only some of the data disks:

      1. Select a smaller cloud instance size with fewer data disks that best fits your needs.

      2. Deselect the volumes that should not be migrated until the number of disks for migration fits the selected instance.

    • The target VM uses up to the maximum allowed number of NICs for the instance size. To migrate only some of the NICs:

      1. Select a cloud instance size with fewer NICs that best fits your needs. At least one NIC is required.

      2. Under Target Workload Settings, deselect the NICs that should not be migrated until the number of NICs for migration fits the selected instance.

        NOTE:The number of data disks consumed by volumes on the target VM cannot exceed the maximum number of data disks supported by the selected cloud instance.

    • In the Cloud Instance Size list, the Supports Premium Storage column indicates the storage account type of the instance: Standard Storage (No) or Premium Storage (Yes). Ensure that your new instance size supports the same storage account type as the target platform.
