Hi there,

Incremental migration is one of the most valuabe features of Migration Suite for SharePoint, especially for larger migrations that take days to complete while business users keep working with their data in SharePoint. You can easily initiate migration of new and updated site content in the Project Mode by selecting the migration job and clicking Run Incremental on the ribbon. The application will pick up every item and document that changed since the previous run and copy them over to target:

   

What if you want the tool to perform recurring synchronizations automatically? In this post, I'm going to walk you through the steps to configure automatic scheduled incremental migrations. It's not as easy as clicking a single button in the UI, but not much harder either.

Notes:

  • If you need to perform incremental synchronization for an entire site, you will need to create the target site (Blank Site) prior to following the steps below

  1. Switch to Project Mode tab in the application
  2. Start the job wizard
  • For site copy
  1. Right-click on the source site, select Copy.
  2. Right-click on the blank target site and select Paste
  • For list/library copy
  1. Right-click on the source list/library and select Copy
  • You can select multiple lists using CTRL or SHIFT
  • Right-click on the target site and select Paste
  • Specify a name for the migration job
  • Specify a recurring schedule for the job using the built-in Scheduling Wizard (e.g. every night)
  • Click Next
  • For site copy, on the second step select to Copy Site to Existing Site
  • Specify copy settings
  • For site copy
  • Expand Advanced Options and check off Incremental Copy
  • For list/library copy
  • Expand List Copy Options and check off Incremental Copy

  • Expand Advanced Options and check Apply Filter
  • Press the Filter button
  • In the Filter Window, select Greater Than for Modified, check the checkbox next to <Empty Date> and set it to a date way back in the past (e.g. Jan 1, 1970).
  • Also check the Use Last Execution Date option
  • Click Filter
  • Click Finish to create the job

After completing these steps you can either start the initial migration manually using the Run command or leave it to the scheduler to start the job automatically. The first run of the task will copy all content from source, while consequent runs will only copy deltas (new and modified items and documents).
