Why migrate to SharePoint Online?

Streamlined collaboration and productivity:

Migrating to SharePoint facilitates unparalleled collaboration and productivity within your team. It offers a central hub for document management, team sites, and intranets, enabling easy access and sharing of information.

Enhanced security and compliance:

SharePoint provides robust security features that protect sensitive information while complying with industry standards and regulations. Migrating to SharePoint means your data is safeguarded with state-of-the-art security measures.

Scalability and flexibility:

As your business grows, so do your needs. SharePoint’s scalable architecture allows you to expand your digital environment seamlessly, accommodating more users and integrating new functionalities without compromising performance.

Integration with Microsoft 365:

For businesses already using Microsoft 365, migrating to SharePoint offers deep integration with the suite’s applications, enhancing efficiency and streamlining workflows across platforms.

Your seamless migration to SharePoint

At Compete366, we ensure a seamless and low-risk transition to SharePoint, designed to enhance your business operations without disrupting your day-to-day activities.

Our migration plan begins by establishing a new SharePoint environment alongside your current file share system. This approach involves copying—rather than moving—your data, ensuring the original system remains intact and unchanged. This dual-environment setup allows for thorough testing and user training while maintaining data integrity.

Migration tasks include:

● Evaluation of folder structure depth and identification of any invalid file types or issues related to file URL lengths, which may require renaming due to SharePoint’s 256-character limit for document URLs.

● Addressing challenges with special characters in file names, large file sizes, and other potential migration obstacles.

  • Configuration of the detailed site architecture, including site collections, subsites, document libraries, and site navigation, alongside the related security infrastructure. This step is crucial for optimising data distribution across SharePoint’s backend databases and services.
  • Implementation of SharePoint security, mirroring Active Directory security principles, to provide tailored access control. This involves creating Security Groups, assigning permission levels, adding users to these groups, and modifying default security settings on SharePoint entities.


While we can theoretically store an unlimited amount of data on SharePoint Online, it’s crucial to design your SharePoint site structure correctly so that we distribute the load across the backend databases and services. As part of the design phase, folders at source often need to be split into multiple document libraries at the destination.

SharePoint security works similarly to Azure Active Directory (now called Entra ID) security. It can be configured to provide fine-grained access control at various levels in the SharePoint hierarchy. At its simplest, it involves creation of Security Groups:

  • assigning permission levels like Full Control / Edit/ Contribute / Read-Only etc. to these Groups
  • adding users to these Security Groups
  • modifying default security on entities like Sites, Libraries, Folders and Files so that the Security Groups (and by extension the users who are part of these groups) have the desired amount of access on these entities.

While we can theoretically store an unlimited amount of data on SharePoint Online, it’s crucial to design your SharePoint site structure correctly so that we distribute the load across the backend databases and services. As part of the design phase, folders at source often need to be split into multiple document libraries at the destination.

We use a specialist SharePoint migration tool (typically AvePoint Fly or ShareGate) and this will be installed on the migration PC / Server. We are AvePoint and Sharegate partners, and the cost of the tool is included in the project, ensuring an efficient and effective data transfer.

After we’ve tested the security matrix and the initial copy of the data, we ask you to test these for yourself to make sure that everything is configured the way you want it. We can train administrators and your users on how to work with SharePoint.

A meticulous comparison of document counts between the source and SharePoint environments highlights any discrepancies or leftover files. We then collaborate with you to address these exceptions, ensuring a comprehensive migration.

Once everything is in place, we ask you for a preferred date for switchover, usually across a weekend. Since the initial data migration and verification stages detailed above could take a few weeks, the source data may have undergone some changes during this period. The objective of the final migration is to sync these changes across to SharePoint just prior to the switchover.


Our commitment to your success extends beyond the migration. Our SharePoint experts remain available for a specified period post-migration to provide support and ensure a smooth transition.

By entrusting your SharePoint migration to Compete366, you benefit from our expert planning, execution, and support, guaranteeing a transition that enhances your business’s productivity and collaboration capabilities without interruption.

What our customers say

“We had one of the Compete366 engineers work with us on the project. He was exceptional and even assisted on some issues caused by the migration which were outside of the 365 domain. Running Office 365 and Sharepoint via an Azure domain gives us a high level of control including user access and data sharing without needing an in-house server to maintain.”

Ed Birks, Managing Director, Langstaff Ellis

The migration project to SharePoint went really well. Once everything was set up, Compete366 simply switched everything over during a weekend and on the Monday morning, our users came in to access all the files they needed on SharePoint.
