Here is a more in-depth migration proposal, including specific tasks, detailed timelines, and additional considerations. --- **Migration Proposal: Migrating 200 Users from Third-Party Hosted Exchange to Azure** ### Executive Summary This proposal outlines the detailed plan to migrate 200 users from a third-party hosted Exchange to Azure, with a focus on ensuring minimal downtime, data integrity, and seamless integration with the ongoing local AD to Azure AD migration project. This document includes an in-depth migration plan, timeline, and budget estimate. ### Project Overview 1. **Project Scope**: - Migrate 200 users' mailboxes from third-party hosted Exchange to Exchange Online (Office 365). - Ensure compatibility and integration with the ongoing local AD to Azure AD migration project. - Minimize downtime and ensure data integrity during the migration process. - Provide comprehensive user training and post-migration support. 2. **Assumptions**: - The current environment includes a third-party hosted Exchange and a local Active Directory. - The local AD to Azure AD migration is a parallel project and will be completed in tandem with this migration. ### Detailed Migration Plan #### Preparation Phase 1. **Assessment**: - **Current Environment Review**: - Conduct a thorough review of the current Exchange and AD environments. - Identify all mailbox types (user mailboxes, shared mailboxes, resource mailboxes). - Inventory of distribution groups, contacts, and public folders. - Assess network bandwidth and connectivity to Azure. - **Data Collection**: - Collect user data including mailbox sizes, mailbox item counts, and shared mailbox details. - Identify dependencies and third-party integrations. - **Risk Assessment**: - Identify potential risks and develop mitigation strategies. - Plan for potential downtime and data loss scenarios. 2. **Planning**: - **Migration Strategy**: - Develop a detailed migration strategy, including cutover and staged migration options. - Define success criteria and key performance indicators (KPIs) for the migration. - **Communication Plan**: - Establish a communication plan to inform stakeholders and users about the migration schedule, potential impacts, and support resources. - Schedule regular updates and feedback sessions with key stakeholders. 3. **Infrastructure Setup**: - **Azure AD Connect Setup**: - Install and configure Azure AD Connect for synchronization between local AD and Azure AD. - Verify synchronization settings and ensure proper user attribute mapping. - **Exchange Online Configuration**: - Verify and configure the domain in Office 365. - Configure Exchange Online Protection (EOP) for email security and compliance. - Set up necessary mail flow connectors and policies. #### Pilot Migration Phase 1. **Selection of Pilot Users**: - Identify a representative group of users (e.g., 10 users) from different departments and roles. - Ensure pilot users cover various mailbox sizes and types (e.g., user mailboxes, shared mailboxes). 2. **Pilot Migration Execution**: - **Preparation**: - Communicate the pilot schedule and expectations to pilot users. - Ensure all pilot users have necessary permissions and access. - **Migration**: - Use Exchange Online migration tools (e.g., Exchange Admin Center, PowerShell scripts) to move pilot users’ mailboxes. - Monitor the migration process closely, focusing on performance, error rates, and user feedback. - Conduct post-migration verification to ensure data integrity and functionality. - **Feedback and Adjustment**: - Gather feedback from pilot users on the migration experience and post-migration environment. - Identify and address any issues or concerns. - Adjust migration plans and strategies based on pilot results. 3. **Training**: - Provide targeted training to pilot users on new features and functionalities in Exchange Online. - Develop training materials and resources (e.g., user guides, FAQs, video tutorials) for broader user training. #### Full Migration Phase 1. **Batch Migration**: - **Batch Planning**: - Divide remaining users into manageable batches (e.g., 50 users per batch) based on department, location, or other logical groupings. - Schedule batch migrations to minimize impact on business operations. - **Batch Migration Execution**: - Perform mailbox migrations for each batch using Exchange Online migration tools. - Monitor each batch for issues and resolve them promptly. - Conduct post-migration verification for each batch to ensure data integrity and functionality. - **Post-Migration Support**: - Provide dedicated support for users during and after each batch migration. - Address any post-migration issues promptly to ensure user satisfaction. 2. **Post-Migration Training**: - Conduct comprehensive training sessions for all users on Exchange Online features and functionalities. - Provide ongoing training resources and support. 3. **Decommissioning**: - Decommission the third-party hosted Exchange environment after successful migration. - Ensure all data is migrated and accessible in the new environment. - Clean up any residual data and configurations from the old environment. ### Timeline The migration is estimated to take 12 weeks from start to finish. Below is a detailed timeline: | Phase | Tasks | Duration | Start Date | End Date | |---------------------------|------------------------------------------------|-----------------|------------|------------| | Preparation Phase | Assessment, Planning, Infrastructure Setup | 3 weeks | Week 1 | Week 3 | | Pilot Migration Phase | Selection, Migration, Training, Feedback | 2 weeks | Week 4 | Week 5 | | Full Migration Phase | Batch Planning, Execution, Support, Training | 6 weeks | Week 6 | Week 11 | | Post-Migration Support | Support, Final Training, Decommissioning | 1 week | Week 12 | Week 12 | ### Budget Estimate The estimated budget for the migration is $40,000. This includes: 1. **Licensing Costs**: - **Exchange Online Plan 1**: $4 per user per month. - **Total for 200 users for 1 year**: $4 x 200 x 12 = $9,600. 2. **Migration Tools and Services**: - **Third-Party Migration Tool**: $5,000. - **Azure AD Connect Setup and Configuration**: $2,000. 3. **Professional Services**: - **Project Management**: $10,000. - **Technical Consultant**: $8,000. - **User Training and Support**: $5,000. 4. **Contingency**: - **Contingency (10%)**: $3,400. ### Risk Management 1. **Risk Identification**: - Potential downtime during migration. - Data integrity issues. - User resistance to change. - Network connectivity issues. 2. **Mitigation Strategies**: - Conduct thorough testing and pilot migration. - Ensure comprehensive data backups. - Provide extensive user training and support. - Monitor network performance and address issues promptly. ### Conclusion This proposal provides a comprehensive and detailed plan for migrating 200 users from a third-party hosted Exchange to Azure. The in-depth migration plan, timeline, and budget estimate ensure a smooth transition with minimal disruption to business operations. The project will be closely coordinated with the ongoing local AD to Azure AD migration to ensure compatibility and integration. --- Feel free to adjust any part of the proposal based on specific requirements or additional details. **Migration Proposal: Migrating 200 Users from Third-Party Hosted Exchange to Azure** ### Executive Summary This proposal outlines the detailed plan to migrate 200 users from a third-party hosted Exchange to Azure, with a focus on ensuring minimal downtime, data integrity, and seamless integration with the ongoing local AD to Azure AD migration project.
