How HashRoot Performs Office 365 Migration Process?

As your Office 365 cloud migration partner, we can effectively tackle all the complexities associated with migration by formulating a structured, risk-mitigated approach. Our migration framework encompasses the following stages

Pre-migration Considerations

Before plunging into the migration from Exchange 2007 to Office 365, our team of migration experts makes a precise plan considering the technical requirements and specific needs of the organization. Driving adoption is about comprehending the business challenges that address with solutions based out of Office 365.

Migration Plan

Before plunging into the migration process our experts will work with you to devise a proper migration plan. We formulate a streamlined discovery and assessment, migration planning phase that lays the foundation for your migration’s success. Our strategic planning encompasses the following

  • Building risk and issue tracking system
  • Developing notes to O365 migration strategy
  • Identifying the email coexistence strategy
  • Devising a plan for mail-enabled applications
  • Documenting all name-spaces and domain names moving forward - UPN, SIP domain. Identifying mailbox size and item counts
  • Identifying Active Directory preparation and remediation requirements
  • Identifying current network links, user concentration and utilization
  • Identifying the operating systems and client applications
  • Identifying the mobile platform used by the organization
  • Define user migrations in batches and document VIPs, managers, and associated admins

Migration Methodology

Existing Infrastructure Assessment

We also conduct a review of client systems to gather and capture information about the existing Exchange 2007 infrastructure. Existing infrastructure assessment helps in identifying gaps in the current ecosystem and delivers detailed recommendations to address the existing gaps. During this phase, we perform the following

  • Infrastructure Planning - (Mail Servers, File Share, Apps that use Exchange and Microsoft Office, Bandwidth, security)
  • Accessing the complexities and risks involved in this migration and pose solutions
  • SharePoint online - (users’ private space and team sites)
  • User experience - (Office 365 web apps, Apps that use Exchange and Microsoft Office)
  • Mobile users - (Office 365 setup & capabilities)
  • Networking and Naming Services Planning
  • Determining environment for migration tools
  • Determine migration plan and examine current DNS records
  • Formulating a plan for Active Directory Federation Services for use with single sign-on
  • Collecting current server information and eventually develop a migration strategy
  • Identifying mailbox size and item counts that will be migrated to Office 365
  • Determining mail-enabled applications and plan for configuration
  • Conducting bandwidth assessment to calculate migration velocity for mailbox data
  • Compiling current users’ information that will be migrated to O365 in the new global standard

Preparation for an Office 365 Deployment

Are you ready for the deployment of Office 365 and take advantage of cloud-based productivity. Our team of experts fine-tunes the workflow to get the deployment up and running. Take a look at our Office 365 deployment checklist

  • Preparing end-user documentation on Outlook and the new Office 365 environment
  • Assist with Domain Verification and Office 365 Registration
  • Adding and verifying domain name with Office 365
  • Creating DNS records to configure the domain name for use with Office 365 services
  • Deploying and configuring Active Directory Services to enable single sign-on
  • Configuring on-premises AD for directory synchronization
  • Exchanging Online Service Configuration
  • Configuring email co-existence with existing server and Exchange Online
  • Mailbox quotas and archival / retention policies
  • Anti-spam and Malware protection in the new environment
  • Configuring client computers and end-user experience


HashRoot utilizes cutting-edge strategies to ensure a smooth rollout to Office 365 with 100% success. We ensure to perform a seamless migration by rectifying the underlying issues. We formulate the following migration checklist that aligns with the organization’s specific requirements

  • Assigning licenses to users in O365
  • Migrating and synchronizing mailbox data to O365
  • Updating DNS to point to O365
  • Configuring Outlook Web Access and Exchange ActiveSync for mobile phones and devices where applicable for mailbox users
  • Migrating exchange mailboxes to Office 365 by batch/department
  • Monitoring and validating migration tool results
  • Validating exchange online functionality
  • Re-run migration for failed files and folders Archive non selected files
  • Perform Post-migration Service Testing of Office 365 functionality

Cutover Migration WorkFlow

Cutover migration method forms an important step for successful migration and it requires careful planning. Cutover migration enables to migrate all of the organization’s mailboxes all at once. Considering the substantial risk and complexity of cutover migration, HashRoot formulates a proven Cutover migration workflow and ensures the tasks to get executed in the right order by the right team, right tools and in the right workstream.


We carry out Quality Assurance and User Acceptance Testing to make sure that the new process meets the user requirements in the real-world scenarios. We ensure to perform complete testing on the following

  • Ensure end-user email is working properly and emails, calendars, and contacts have been migrated
  • Ensure end -users can access, edit and upload all kinds of files to the cloud-based on security access
  • Ensure that all documents with links are working properly
  • Ensure that all applications that use Exchange Online and Microsoft Office are working properly in all the devices with Microsoft supported compatibility


Before we sign off the project, we offer a training program so that the organization can effectively utilize the new technology we have applied. Our training program covers the following

  • Office 365 users training with the department
  • New file organization users training
  • Provide client computers support on configuration


We prepare a precise documentation report which acts as a reference guide to know everything about the migration project. This helps to take remedial actions in case of any issue that arises in the future.
