Document Migrations

This guide covers general information about how document migrations should be prepared for and performed. It is intended to be generalized information for those new to document migrations in MigrationWiz, rather than specific, and should be used in conjunction with your environment and migration guides. 

Document migrations function differently from Mailbox migrations as far as environment preparation and the advanced & support options utilized. 

Document Migrations

Performing a Document Migration

Document migrations follow a general basic flow:

  1. Prepare your source environment (as outlined in your scenario-specific migration guide).
  2. Prepare your destination environment (as outlined in your scenario-specific migration guide).
  3. Verify license quantity and apply (if using UMB licenses). [LINK]
  4. Create a Document migration project (these steps are outlined below).
  5. Create or apply endpoints [LINK].
  6. Add users (this, and all following steps, are laid out in the migration guide for your scenario).
  7. Apply Advanced & Support Options (as directed in your migration guide). 
  8. Verify credentials.
  9. Notify users.
  10. Run the migration.
  11. Retry errors.
  12. Post-migration steps. 

To set up a document migration project, perform the following steps in order:

  1. Click the Go to My Projects.
  2. Click the Create Project.
  3. Create a Document project.
  4. Click Next Step.
  5. Enter a Project name and select a Customer.
  6. Click Next Step.

Advanced & Support Options for Document Migrations

Importing data:
