The following table describes the fields on this page:

Item Description
Policy Identification This section allows you to specify a name to identify the migration policy.
Name Name for the new data migration policy.
Migration Path This section allows you to specify the data migration path to be used by the migration (or reverse migration) policy.
Migrate Data When creating a migration policy, this section displays the data migration source and target information:
  • Primary EVS/File System: Displays the name of the EVS and file system for primary storage (the migration source).
  • Virtual Volume:Virtual volumes do not apply to the Data Migrator to Cloud.
  • Secondary Target Type: Displays Cloud to represent the migration type.
  • Secondary File System: Displays the name of the file system on secondary storage that will host the migrated data (the migration target).

(To create paths, see Data Migration Paths) Advances to the Data Migration Paths page, which allows you to create data migration paths.
Pre-Conditions

This section allows you to specify the rules (the criteria) that the files must match/meet in order to be migrated or reverse migrated (reverse migration is for Data Migrator only not Data Migrator to Cloud) by this policy.

Available Cloud Rules Rules with specific threshold limits are displayed here. This list of rules define the set of conditions which trigger the migration/reverse migration. You can:
  • Add a Pre-condition to the Selected Rules list by selecting it and clicking the right arrow (>).
  • Remove a rule from the Selected Rules list by selecting it and clicking the left arrow (<).

This policy will be run either according to a defined schedule, or when started manually. Once the policy is run, the threshold specifies when the selected rules are applied. You can specify that the selected rules will be applied when either of the following conditions are met:

  • When the primary file system's free space falls below X% (set the percentage level for this condition).
  • When other conditions are not met. These conditions are defined in the selected rule(s).

After selecting rules and the threshold, save the policy by clicking OK.

Selected Cloud Rules Displays the rules containing the criteria/conditions to be used to determine if a file should be migrated. The criteria in the rules are applied when the threshold (the when condition specified in the Available Rules section) is met.
(To create rules, see Data Migration Rules) Advances to the Data Migration Rules page, which allows you to create rules.
