Teach for America, a renowned American nonprofit organization focused on education, needed to consolidate in Microsoft 365. But their journey was riddled with several challenges, including communicating the transition to a large user base, migrating inner file permissions accurately, mitigating API throttling, and more.

2) Adenza’s acquisition-driven migration to Microsoft 365

Adenza, another prominent US-based company (in the financial technology industry), needed to migrate to Microsoft 365 for an acquisition that they were undergoing. They had a unique set of challenges, including single ownership of the entire data in Box cloud, limited number of Box API calls, and more.

Our migration team provided them with several strategies and solutions, including decentralizing data ownership in Box, purchasing the required number of Box API calls. As a result, Adenza was able to migrate the entire users and data they planned to. Accurate preservation of context was also one of the key migration outcomes.

From this case study, we can learn that:

• Decentralizing data ownership is a must before migrating.
• Checking Box licenses and ensuring availability of ample API calls is a must.
• Proper planning helps streamline M&A-driven migrations.

US-Aligned Migration Approaches

For more insights, we have shared some migration approaches that are specific to US-based private companies as well as government agencies. Check them out below:

1) Aligning the Migration with SOC 2 Type 2

Migrating from Box to Microsoft 365 (or across other cloud platforms) in the US requires stringent SOC 2 Type 2 compliance. SOC 2 Type 2 requires data encryption at rest and at transit, evidence of process monitoring and incident detection, etc. It is must for both the customer and migration vendor to adhere to these compliance requirements.

2) US-Specific Factors that Influence Migration Roadmap

There are several factors specific to the US that influence migration roadmap of many US-based companies, including:

• SOC 2 Audit Windows: The audit observation period required for SOC 2 Type 2 can have a duration of 6 to 12 months. As such, the pattern of starting migration ahead of business expansion is common among many US-based companies.
• Enterprise Procurement Cycles: Large enterprises in the US often have annual vendor security reviews. Factors such as vendor risk assessments and security questionnaires can influence migration timelines.
• US Government Fiscal Year: Many government agencies often align their migration roadmap and timeline with the federal fiscal year which typically runs from October 1 to September 30.

3) Strategies Specific to Migrating to Microsoft 365 GCC

US government agencies and contractors migrating to Microsoft 365 GCC (Government Community Cloud) must meet stricter compliance requirements. Implementing identity security, compliance policies, and data sovereignty measures are highly important.
