​​Public Folder Migration Guide From On-Premises Exchange 2007+ to On-Premises Exchange 2007+ > 50GB

Important: When you sign in to MigrationWiz, you are redirected to the Getting Started page in MSPComplete. To get to a migration project created before April 4,​ 2017, click the Go to Projects button on the Getting Started Page. To create a new project for the migration scenario documented in this article, click the waffle icon (waffle.png) in the top navigation bar of MSPComplete, and select the appropriate migration product.

Introdu​ction

  • This is the complete Onboarding Task flow for migrating Public Folders from one On-Premises Exchange 2007+ Public Folder server in one organization to an On-Premises Exchange Public Folder server in another organization.
  • This guide should be followed if the total size of the Source Public Folders is more than 50GB. If less than 50GB, refer to KB005142.
  • Complete each step in order. If additional instructions are required, a link to a corresponding Knowledge Base article is provided.
  • Due to a code defect in Exchange 2010, timestamps will not be preserved for Public Folders at the Destination. KB005159

Prepare Source Environment

  • Set elevated 'Organization Management' admin role to migrating admin account (this grants permission to all necessary read-only fields). KB004788
  • Ensure migrating admin account has permission on all Public Folders (owner access rights need to be permitted to the account being used for migration). KB005103
  • Split up large Public Folders. If any Public Folders contain more than 20,000 items (if Source = Exchange 2007), or 100,000 items (if Source = Exchange 2010 or later), these should be split into multiple Public Folders. This will speed up your migration. KB005526

Prepare Destination Environment

  • Create a top-level Public Folder on the Destination.
  • Grant administrator account (account that is being used for migration) full owner permissions to the root Public Folder at the Destination. KB005103
  • Enable remote PowerShell on the Destination Exchange server (this is important, so that MigrationWiz can mail-enable the Public Folders during migration). KB005111

MSPComplete Steps

  • Create customer. KB005421
  • Create the Source and Destination endpoints (select Exchange Server Public Folder ​ as the endpoint type, for both the source and destination endpoints). KB005427
  • Launch public folder migration (select All Products > Public Folder Migration).

MigrationWiz Steps

  • Set up Project (create Public Folder project/Name project and select MSPComplete customer/Select Source endpoint/Select Destination endpoint).
  • Add Public Folders. To understand how pricing works, refer to KB004863.

    Options:
    • Choose to migrate all Source public folders.
      • Select Add/Quick Add and enter a forward slash ( / ) within the field labeled Root Folder Path. KB004914
    • Use BitTitan AutoDiscover to discover all Public Folders on the Source, and then import them into your MigrationWiz dashboard. This allows you to pick and choose which Public Folders to migrate. Each top-level folder will consume one Public Folder license. KB004915
      • Select Add/AutoDiscover items/Start Autodiscover/Import.
  • Run Verify Credentials. KB004511
  • If the Source Public Folders have more than 1000 folders below the top-level folder, work with BitTitan Support so that the migration can be split up, based on migration points after every 1000 folders. KB005239

    Note: Once the tool is complete, you must run the migration from the new project, and can then delete the original project.
  • Purchase Public Folder licenses. KB004647
    • To obtain an estimate of the number of Public Folder migration licenses required for your migration project, follow the directions in KB005791.
  • Set Project Advanced Options. KB004834
    • Set value for Licensing/Maximum licenses to consume per item per pass licensing count. Default = 1. This allows up to 10GB to be migrated. Example: If migrating all Public Folders, using the forward slash ( / ), and the total data size = 78GB, then increase this value to 8 (otherwise the migration will pause at 10GB). If using AutoDiscover, and the largest top-level folder = 37GB, increase this value to 4. Refer to KB004890 and KB004863.
    • Add RemoveFilterBasedOnFolderType=1 under Support/Support options. This flag is required if Public Folders contain items other than mail, such as calendar and contact items. KB005053
    • Set Preferred BitTitan Data Center. For fastest migration speeds, select the Data Center that is closest to your Office 365 Destination tenant. KB004268
  • First Pass MigrationWiz Steps:
    • Set first pass Project Advanced Options: KB005067
      • Remove: MaintainWatermarkCompletionState=1
      • Add: MaintainWatermarkCompletionState=1
      • Set date to migrate items older than six (6) months.
  • Perform Full Migration pass (put a checkmark in the box next to Root Path, select the Start button > select Full Migration from the drop-down list > click on the Start Migration button).
  • Perform a final Full Migration pass using the Advanced Option AllowAllMailboxTypesForPFPermissions=1 in order to migrate all Security Group Permissions. If you do not run the second pass, none of the Security Group Permissions will migrate.
  • Second/Final Pass MigrationWiz Steps:
    • Set second pass Project Advanced Options: KB005067
      • Remove: MaintainWatermarkCompletionState=1
      • Add: SkipImportFolderWhenPublicFolderExists=1
      • Set the date to migrate items newer than six (6) months.
  • Perform Full Migration pass (put a checkmark in the box next to Root Path, select the Start button > select Full Migration from the drop-down list > click on the Start Migration button).
  • Receive migration statistics (click on the pie chart on the MigrationWiz dashboard to receive an email containing all the project migration statistics). KB004626
