SharePoint On-Premises to Online Migration-Planning, Checklists & Best Practices

Introduction:

Many organizations are looking to replace their legacy on-premises environments and platforms. But before we dive into how to create an overall SharePoint on-premises to SharePoint online migration plan, let us first explore three important topics to consider for your pre-migration strategy.  

The Content

Content size plays a crucial role in the construction of a successful Migration Strategy. What worked well for a 1 TB migration may not play well when the content size is huge like 20 TB! 

The content size can be SMALL (less than 1TB), MEDIUM (anything between 1-20TB), and LARGE (>20TB). Categorizing content size allows companies to better understand key strategic points about file sizes, item count, list records etc. thereby giving a clearer picture of what can be expected at the target. 

Gather Requirements 

Gathering inputs from stakeholders who will be impacted by this migration is crucial. 

  • Stakeholders should be aware that not all features of the legacy system can be ported over to the new system. Often, some architectural changes are needed to deal with deprecated and added features of SharePoint Online. Educate stakeholders on the disparities between the two platforms and when it makes sense to introduce customization to overcome some of the differences, with a full understanding that with customization comes increased cost/time to complete the project. 
  • Custom solutions can be extremely critical to business owners and may not be supported as-is on the target platform. Review all custom solutions on the source systems with the key stakeholders and suggest alternate out-of-box features before trying to replicate any custom solution in the target system. 
  • Assess business owners’ requirements and estimate how much time is needed to prepare for the migration and adapt to any changing business processes. 
  • Know the organization; know its culture. Conduct surveys and collect feedback from the organization’s business owners/domain champions/influencers/stakeholders.  

Make It Simple. Let the Data tell the Story 

Data insights can help drive your Migration Strategy. Collect data from the source system and use visualizations from a tool such as Power BI to tell the story and help the key stakeholders better understand how the current system is being used.

The Migration Strategy 

Once you understand the content, have reviewed the requirements and explored migration options, you can start to formulate a migration strategy. 

  1. What content are you migrating and how much? Have you defined the scope? 
  2. Are the impacted departments/stakeholders aware of the migration? Create a timeline and a communication plan. 
  3. Are users comfortable using the target platform? Create an adoption and change management (ACM) plan and involve subject matter experts from both the business and migration team using a train the trainer approach. 
  4. Perform a migration mapping with complete documentation that has been vetted by the business owners. 
  5. Create Proof of Concepts to demonstrate any new features 
  6. Estimate the project timeline, considering both out-of-box and custom solutions needed for the target platform.
  7. Ensure that content to be migrated adheres to SharePoint limitations, such as item counts in a library, file size, long URLs, special characters, etc. 
  8. Summarize and communicate all migration strategy decisions in a formal document and review it with the business owners. 
  9. Conduct a test migration and review the results with the business owners before performing the full migration.

Here are some final takeaways to consider when planning your migration:
  • Migrations are often phased and require flexibility. Technology should not be the key driver beyond your migration decisions.
  • Migrations are often iterative – requiring a need to iteratively plan, execute, and release. Your migration approach will determine how much iteration is required.
  • Be prepared for errors due to differences in the source and target platforms.
  • Inventory and define what will be removed, transformed, or modified.
  • Communicate changes early and often to key stakeholders and ensure that they are aware of what is coming next.
  • A cohesive adoption and change management strategy is important for a successful migration.
