This practical pre-migration checklist provides a step-by-step guide to help London SMBS prepare for a seamless Microsoft 365 migration.
Audit Your Existing IT Environment
Start by auditing your current IT infrastructure. This includes evaluating your email systems, file storage, applications, and user accounts. A clear understanding of your current setup is essential to planning your migration.
Checklist:
- Identify all email accounts, shared mailboxes, and distribution groups
- Review data volumes and formats to be migrated
- Map out integrations with existing third-party tools or internal systems
Define Clear Migration Objectives
Set specific goals for your Office 365 migration in London. Common objectives include:
- Improving communication and collaboration
- Enhancing data security and compliance
- Reducing operational costs
Knowing your objectives will help shape your migration strategy and measure success afterwards.
Choose the Right Microsoft 365 Subscription
Microsoft 365 subscription plans offer several businesses, each tailored to unique needs. London SMBS should assess what features they require, such as cloud storage, advanced security, or Microsoft Teams.
Popular choices include:
- Microsoft 365 Business Basic
- Microsoft 365 Business Standard
- Microsoft 365 Business Premium
Compare each plan based on your business priorities before proceeding.
Plan Internal Communication and User Training
Employees must be informed about the migration well in advance. Excellent communication will help reduce resistance to change and ensure a smoother transition.
Recommendations:
- Announce the migration timeline and what users should expect
- Organise Q&A sessions or briefings with teams
- Schedule training to support post-migration adoption
Clean Up and Organise Data
Data clean-up is a vital step. Unused or outdated files should be archived or deleted to ensure that only necessary data is migrated.
Tips:
- Delete duplicate or obsolete data
- Review folder structures for logical consistency
- Flag any sensitive files for special handling
A well-organised dataset results in a faster, more efficient migration.
Review Compliance and Security Requirements
Businesses must ensure they comply with UK regulations, including GDPR. Data should be protected with encryption and secure protocols during migration.
Key points:
- Review legal obligations around data storage and handling
- Consider additional security features like Multi-Factor Authentication (MFA)
- Identify any data residency or sovereignty concerns
Create a Detailed Migration Plan
Develop a step-by-step roadmap covering:
- Migration type (cutover, staged, or hybrid)
- Timelines and milestones
- Risk mitigation strategies
- Rollback plans in case of errors
This plan ensures everyone involved knows their responsibilities and the process runs smoothly.
Test the Migration with a Pilot Group
Before going live, test the process on a small group of users. This will help identify technical issues and gather feedback for improvement.
Pilot testing allows you to:
- Evaluate data integrity post-migration
- Monitor user access and system behaviour
- Resolve compatibility issues in advance
Backup All Critical Data
It is essential to back up existing data before starting the migration. This provides a safety net for technical failures or data loss.
Ensure the backup includes:
- Mailboxes and shared folders
- Calendars and contacts
- File server data or local document libraries
