Table: Create Migration Plan wizard options

Field	Description
Components Selection
Name	Enter a name for the migration plan. The maximum length of the name should be 128 characters. The following characters are allowed: A to Z a to z 0 to 9 _
Description	Enter a description or any additional information for the migration plan.
Select data migration type	Select one of the following: VxVM Mirroring VVR Replication
Select a service group to migrate using this plan	Click Browse and select the service group that you plan to migrate using this plan. Veritas recommends that the service group you select for migration must be online in the source cluster
Select a target cluster to migrate to using this plan	Click Browse and select the target cluster to which you plan to migrate to using this plan.
Cluster Information & Dependency
Cluster Information	Displays the source and target cluster details. The following details are displayed: OS version VCS version VxVM version Note: VCS and VxVM versions in the target cluster must not be lower than the version in the source cluster.
Use existing service group(s) in the target cluster	Option is enabled and selected if the target cluster has service groups of the same name that are part of the entire dependency tree for migration from source.
Create new service group(s) in the target cluster	Option is enabled and selected if there are no service groups or resource names in the target cluster that matches the name of the service group or the resources present in the entire service group dependency tree selected for migration. In this scenario, the application migration plan creates all the service groups selected as a part of the migration. For Cluster Volume Manager (CVM) migrations, this option is enabled even if the CVM group is present in the target cluster as well as in the service group dependency tree which is to be migrated. Veritas recommends that you must not deselect the CVM service group during migration. If you opt to deselect the CVM service group, dependency with CVM service group is not created in the target cluster and may affect while bringing the service group online with correct dependency.
Dependent Service Groups for Migration	You can deselect any dependent service group(s) that need not be migrated. However, Veritas does not recommend deselecting any service group that is in the dependency tree. This may affect the application when it is brought online in the target cluster.
Target Disk Information - Panel appears if you select VxVM Mirroring
Service Group to be Migrated	Displays the name of the service group which has a CVMVolDg or DiskGroup type resource configured in it.
Disk Group	Displays the name of the disk group. Only disk groups configured with CVMVolDg or DiskGroup resources are displayed. If a disk group is not configured under any resource, that disk group is not displayed.
Action	Use Existing - Option is enabled only if there are existing linked break-off snapshots for any source disk groups part of the migration. If snapshot is found for any disk group, the corresponding disk group is shown as Mirrored. Select this option if you want to use the mirror disk group pre-configured for migration. Create New - Option allows you to create a new mirror disk group for a disk group. Option is enabled by default if there are no pre-configured mirror disk groups for a disk group. In this scenario, the corresponding disk group is marked as Not Mirrored. Ignore - You can ignore a particular disk group resource from being migrated. Veritas does not recommend to ignore any disk group as the data present in these disk groups will not be migrated.
Sub-Action	Select Disks - If you opt to create a new disk group, click Select Disks to select the set of disks for creating the mirror disk group. The Select Disk(s) window displays only the set of disks in the source cluster that are shared between all the target cluster managed hosts. You can select multiple disks so that the combined space of the selected disks is greater than the source disk group space; this is validated when you click Next.
RVG Information - Panel appears if you select VVR Replication
Service Group to be migrated	Displays the name of the service group which has a CVMVolDg or DiskGroup type resource configured in it.
Disk Group	Displays the name of the disk group. Only disk groups configured with CVMVolDg or DiskGroup resources are displayed. If a disk group is not configured under any resource, that disk group is not displayed.
Action	Use Existing - Option is auto-selected if the disk group has existing RVGs and for all RVGs secondary sites are added. The secondary site for all RVGs should be one of the nodes of the selected target cluster. If a disk group is marked as Use Existing, the workflow does not take any action on these disk groups and you must establish replication for these disk groups to ensure data sync. This is validated during Rehearse and Migrate operations. Create New - If a disk group is marked as Create New, the workflow creates the necessary entities on the source and target cluster nodes for replication to be established for that disk group. Option is auto-selected for the disk group when one of the conditions is met: Has no RVG created. Has RVGs created but no secondary added. Has RVGs created and few or all RVGs has secondary sites added. None of the secondary site of any RVG should be a node which is part of the target cluster. Ignore - If a disk group is marked as Ignore, the disk group is not included for migration as part of the workflow. Option is auto-selected for the disk group when one of the conditions is met: If RVG does not exist in the disk group and the disk group does not have sufficient space to create SRL volume. Has RVGs created and few or all RVGs have a secondary site added, out of which few RVGs have secondary site as one of the nodes of the selected target cluster and few RVGs have secondary site as a node which is not part of the selected target cluster. Configuration issues mentioned above which caused the disk group to be marked as Ignore can be resolved as follows: For the first scenario, either increase the size of the source disk group or define the required SRL volume size in the environment file according to the free space available in the disk group. For the second scenario, maintain consistent configuration across all RVGs in a disk group. After resolving the configuration issues, click Previous to go back to the previous page and then click Next to revalidate. Note: You can also ignore a disk group as part of the migration process, but Veritas does not recommend this.
Sub-Action	Select Disks - If a disk group is marked as Create New, disk information must be provided. Click Select Disks for each disk group to provide the target disks on which the disk group for replication needs to be created. Note: Combined space of disks selected should be greater than the sum of space used in the source disk group, calculated SRL volume size, and cache volume size. You must not select the same disk as part of two disk groups.
RLink Details	RLink Details - If a disk group is marked as Create New, RLink details must be provided. Click RLink Details to provide RLink information for each disk group: NIC for each node of source and target cluster where the IP for RLink needs to be plumbed. IP which is to be used for the disk group on source cluster and target cluster for setting up RLinks for replication. Note: The NIC selected for a disk group for all nodes of source and target cluster should have same version of pre-existing IP plumbed on it (either IPv4 or IPv6). IP which is provided for a source cluster and target cluster should be unique for disk groups across service groups. Same IP can be given for disk groups which are part of the same service group.
Network Configuration
Service Group Name	Displays the name of the service group under which network resources are configured.
Resource Name	Displays the name of IP-related resources.
Network Parameters	The following are the network parameters: Device IP Netmask
Source Details	Displays the network details of the source.
Target Details	Displays the network details of the target. You can edit the target network details. The target details must be in the same format as the source. As an example, for IPMultiNIC resource, if NIC field displays `net1,1,net2,2` in source, the target information that you provide must be in the format eth0,1,eth1,2.
Task Customization
Tasks	Displays the list of all tasks that will be executed as a part of the following application migration operations: Setup Storage Rehearse Migrate
Add Pause	Allows you to add a pause after any predefined task.
Add Script	Allows you to add a task for custom script execution on a specific cluster node.
Delete	Allows you to delete a pause task or custom script execution task that you added. You cannot delete a predefined task.
Summary	Displays a summary of the application migration plan.

While creating the application migration plan, a query is executed on the source and target cluster nodes and this could cause a delay when moving from the Cluster Information & Dependency panel to the Target Disk Information panel. The query fetches the following details:

VxVM Mirroring - Existing mirroring configuration
VVR Replication:
- Existing RVG configuration
- Space validation on source disk group
- Space required for target disk group
- Network details like NIC, IP, and netmask of all the source and target cluster nodes

To create an application migration plan

In the Management Server console, go to the Availability perspective, expand Solutions in the left pane and click Application Migration Plan.
In the Migration Plan pane, right-click and click Create.
The Create Migration Plan wizard opens.
In the Components Selection panel, specify a name and description, select the data migration type, and select a service group and target cluster.
Click Next.
In the Cluster Information & Dependency panel, you can view the cluster details and modify the dependent service groups, if required.
Use existing service group(s) in the target cluster and Create new service group(s) in the target cluster options are disabled and you will not be able to proceed if there are few service groups or resources in the target cluster which are present in the service group dependency tree that is being migrated. In this scenario, you have to cancel the operation, do one of the following, and then create the plan again:
- Delete the conflicting service groups/resources on the target - This enables the Create new service group(s) in the target cluster option.
Or
- Create the cluster configuration in the target cluster manually - This enables the Use existing service group(s) in the target cluster option.
Click Next.
If you selected VxVM Mirroring as the Data Migration Type, go to 5.
If you selected VVR Replication as the Data Migration Type, go to 6.
In the Target Disk Information panel, you can view the disk groups and select disks for creating mirror disk groups, if required.
If any disk group which is mirrored with the source disk group is configured under DiskGroup or CVMVolDg resource, this disk group is also displayed and is marked Not Mirrored. However, the source disk group is marked as Mirrored. In this scenario, you can ignore the mirror disk group and choose Use Existing or Create New for the source disk group.
If the disk group is mirrored and the disks used to create the mirror disk group are not present in all nodes of the target cluster, the disk group is marked as Mirrored. However, the Use Existing option will not be enabled.
If the disk group resources are not online in the source cluster or the XPRTLD daemon is not running in the source cluster nodes, the wizard will not be able to detect the state of the disk groups. In this scenario, the disk groups will not be marked as Mirrored or Not Mirrored.
If there are no disk groups for migration or if you select Ignore for all the disk groups listed, an error is displayed and you will not be able to proceed.
Click Next. Go to 7.
In the RVG Information Panel, you can view the disk groups, select disks, and enter RLINK details for creating replication configuration.
Disk groups are marked as Replicated if RVGs are configured in it; it does not depend on whether a secondary site is added or not to these RVGs. Disk groups are marked as Not Replicated if the disk groups does not have any RVGs configured.
If there are no disk groups for migration or if you select Ignore for all the disk groups listed, an error is displayed and you will not be able to proceed.
Click Next.
The Network Configuration panel displays details of network resources configured in any service groups being migrated. You can edit the target network details of these resources.
Note:
In the Rehearse operation, IP-related resources are converted to FileOnOff type resources as part of cluster configuration in the target so that resource dependencies are maintained and to ensure that there will be no network connectivity to the applications which are brought online in the target, but NIC related resources are configured.
In Migrate operation, both IP and NIC related resources are configured in the target cluster.
For VVR Replication, IP resources configured to monitor IPs used for any existing replication configuration are not displayed.
Click Next.
In the Task Customization panel, you can view the list of all tasks that will be executed as a part of each operation. You cannot modify or delete a predefined task. After any predefined task in an operation, you can add a pause task or custom script execution task. These tasks are executed in the order specified during the course of the operation. You can also see whether a task is marked as critical or not. If any critical task fails, the entire operation fails.
See Understanding user-defined tasks.
