General Questions

What is included in a Microsoft 365 migration?

Our Microsoft 365 migration service includes complete planning and assessment, tenant setup and configuration, email migration (including all messages, contacts, and calendars), file migration to OneDrive and SharePoint, user account creation and licensing, security and compliance configuration, mobile device setup, end-user training, and post-migration support. We handle every aspect of the transition so you can focus on your business while we ensure a smooth migration with zero data loss.

How long does Microsoft 365 migration take?

Migration timelines depend on your organization's size and complexity. Small businesses (under 25 users) typically complete migration in 1-2 weeks. Medium organizations (25-100 users) usually take 2-4 weeks. Larger or more complex migrations may require 4-8 weeks or more. We can often run migrations in parallel with your existing systems, allowing testing and training before the final cutover. During your assessment, we'll provide a detailed timeline specific to your situation.

Will we lose any email or data during migration?

No. Our migration process is designed for zero data loss. We use proven migration tools and methodologies that copy all your data—including emails, contacts, calendars, and files—to Microsoft 365 before the cutover. We verify data integrity throughout the process and perform multiple validation checks. Your original data remains in place until migration is confirmed successful. In our experience, properly executed migrations result in complete data preservation.

Can you migrate from any email system?

Yes, we migrate from virtually any email platform to Microsoft 365. Common migration sources include Google Workspace (G Suite), on-premise Exchange servers, hosted Exchange, IMAP-based email systems (GoDaddy, Rackspace, etc.), POP email accounts, and other Office 365 tenants. Each platform has specific migration paths and considerations, and we have experience with all of them. We assess your current environment and recommend the optimal migration approach for your situation.


Cost & Training Questions

How much does Microsoft 365 migration cost?

Migration costs depend on the number of users, amount of data, source system complexity, and any special requirements. Small business migrations (under 25 users) typically range from $1,500-$5,000. Medium organizations can expect $5,000-$15,000. Enterprise migrations vary widely based on complexity. Microsoft 365 licensing is separate and ranges from $6-$57 per user per month depending on the plan. We provide detailed quotes after assessing your specific requirements.

Do you provide training for Microsoft 365?

Yes, end-user training is included in our migration services. We provide training on Outlook, Teams, OneDrive, SharePoint, and other Microsoft 365 applications your team will use. Training can be delivered live (on-site or virtual), through recorded videos, or via written guides—whatever works best for your organization. We also offer ongoing training for new employees and advanced training for power users. Proper training ensures your team gets full value from Microsoft 365 from day one.

What Microsoft 365 plan do we need?

Business Standard ($12.50/user) adds desktop Office applications. Business Premium ($22/user) includes advanced security features ideal for most businesses. Enterprise plans (E3/E5) provide additional compliance and analytics features for larger organizations. We help you select the right plan during assessment, ensuring you get the features you need without paying for unnecessary extras.
