Microsoft 365 E5 to E7 Upgrade Migration Checklist: 5 Easy Steps

Microsoft 365 E5 to E7 Tenant consolidation checklist consists of five straightforward steps. Implement them in the same order to ensure a smooth, flawless Microsoft 365 E7 migration.

Step #1: Pre-Migration Assessment (Calculate License Usage, Enterprise Agreement, and AI Budget)

• Start by assessing your current M365 E5 license usage. Review all active users, shared mailboxes, and distribution groups throughout all the source tenants.
• Check the current Enterprise Agreement (EA) terms. This includes understanding mid-term upgrade policies. It will promise a smooth transition to the E7 license.
• Next, identify the exact number of users required for Copilot and Agent 365. Including users who just need a basic E5 license (no AI assistance required). Also, calculate storage requirements for the new tenant. Simply, use data footprint in SharePoint, OneDrive, and Teams.
• Use Copilot Studio to calculate expected AI agent consumption. It will be separate from the standard $99 E7 licensing fee.

Pro-Tip: Upgrade to M365 E7 license or renew E5 before July 1, 2026. Because the new Microsoft 365 price hike will take effect after that. Plan according to your Enterprise Agreement.

Step #2: Prepare for Tenant Consolidation (Merge Workloads)

• Finalize the “target” tenant for E7 ( the new Agent365-powered tenant).
• Wiping out the active directory (duplicate identities, orphaned accounts, and legacy B2B guest accounts) is a must. Because Microsoft’s Entra Suite’s advanced identity controls require a fresh, unaltered Active Directory.
• DNS records (MX, SPF, DKIM, and DMARC). It will prevent message delivery-related disruptions during the maintenance window.
• Finally, consolidate workloads (mailbox items, SharePoint Items, Teams channels) into the new E7 tenant. It is a non-negotiable step that makes sure your data is combined before activating Agent 365. Otherwise, if you upgrade from E5 to E7 license with messy data and poor permissions across multiple tenants due to any of the following reasons:

• Merger
• Acquisition
• Or Shadow IT

The new AI agent will not only hallucinate but also pull incorrect data and violate compliance rules. And end up surfacing sensitive company information to the low-level employees and guest users.

So, to consolidate the workloads of multiple tenants, use native Microsoft Tools. Or super-helpful, third-party migration tools like SysTools Office 365 to Office 365 Migration Tool.

It will automate the complete tenant migration for you. And guarantee a smooth & secure bulk tenant migration, including complete mailbox items, SharePoint Items, Teams channels, more.

Here’s how you can automate centralizing workloads. And ensure a secure and accurate E7 AI rollout

Step #3: Data-Security Protocols (Applying M365 Purview Labels, DLP Policies, and More)

Data-security protocols ensure Copilot cannot access and surface sensitive organizational information. Prompting it to deliver the updated, accurate responses. Even accredited studies highlight that, on average, 802,000 files are compromised due to oversharing, broken permissions, or incorrect classification.

Hence, it becomes an unskippable step to be executed before implementing Microsoft 365 E7 for Enterprise.

So, if you have decentralised data and permission sprawl, check out the. It avoids “AI Grounding Failure”. And protect confidential data from Copilot.

• Use SharePoint Admin Center to generate a permission state report. The report will highlight all the sites with guest access and open sharing links. And set a compulsory expiration rule for all “Anyone with the Link”. Including turning off anonymous sharing for highly-privileged sites.
• Assess document libraries and remove “Everyone Except External Users” (EEEU) groups. Make sure it gets removed from HR, Finance, and Executive Libraries. And, interchanged with monitored M365 Groups.
• Locate, archive and remove “Dark Data” to fix “Copilot is generating inaccurate responses”. It can be stale Teams channels or outdated SharePoint sites. In a nutshell, delete every redundant, obsolete, or trivial data.
• To do so, utilize SharePoint Advanced Management (SAM) or the native built-in native storage metric. It will assist you in filtering out the Teams and SharePoint sites with no activity.
• Use Microsoft Purview Sensitivity Labels to protect your organization’s privileged data. It dictates what and how Copilot uses a file or document. Even though it is in the public folder. You’re required to submit your data taxonomy.
• Update Data Loss Prevention (DLP) rules. It blocks Copilot from accessing delicate information by covering AI prompts and outputs.

Step #4: Activate Entra Suite (Setting Up Zero-Trust Boundaries)

Microsoft 365 E7 uses AI agents that act on behalf of human users. Conventional network security is not adequate. Because if a user’s identity is exposed or compromised, the attackers will gain access to the files and the AI agents. Hence, deploying Entra Suite is non-negotiable.

• First, set up automated rules for users. It will instantly revoke or update access to specific SharePoint sites and connect AI agents when a user shifts to a different department.
• Ensure only authorized or top-level users can set specific automated workflows. To do so, automate quarterly access reviews for highly privileged AI agents.
• Configure Entra Private Access to create per-app, per-session verification. It will assess the context of the query made by an AI agent on the on-premise database through a connector in real-time. And if the endpoint is not secure, it will prevent lateral movement (suspicious activity).
• Make sure you route the web traffic via Entra internet access. It is a secure web gateway that prevents malicious sites. Including restricting AI agents from hijacking and downloading malware or removing data to unauthorized domains.
• Lastly, review & upgrade the Conditional Access Policies. Set them up to require phishing-resistant MFA every time a user accesses the Agent 365 control plane. Or create advanced AI agents in Copilot Studio. You can UseFIDO2 security keys or Windows Hello for Business. Also, schedule strict session timeouts. Especially for administrative roles. It will ensure continuous verification.

Step #5: Configuring Agent 365 and AI Adoption

• Set up a unified registry for every agent across the organization. Simply go to Microsoft 365 Admin Center and use the Agents hub >> sync all the active agents in the environment. Counting in agents built in Copilot Studio, Microsoft Foundry. Including the third-party platforms via the SDK.
• Configuring Microsoft Purview and Data Loss Prevention rules is the most critical security step. It restricts an AI agent from reading and surfacing files. Including stealing sensitive data from the network via an agent-drafted email. So, add “Highly Confidential” sensitivity labels to privileged files. And establish strict DLP rules.
• Also, enable Defender for AI agents. Exercising this will make sure that agents are not being manipulated by prompt injection attacks (harmful prompts).
• Next, assign the E7 license to your new user base >> Activate Microsoft’s purpose-built agents (Researcher, Analyst, or Project Manager Agents) within the Copilot Chat and Teams. It will allow users to use the advanced capabilities of AI.
• Educate employees to delegate multi-step, complex tasks to AI agents. Also, apply formatting rules and analyse the agent’s output for better accuracy. You have to shift from basic “prompt engineering” to “Copilot Cowork”.
• Set up the system to send automated alerts for the security operations team. It will notify them when an agent starts downloading or querying sensitive data. Especially in unusual volume.
• In the end, continuously monitor AI agents to review how they are being used. And what data they’re surfacing. It will help in determining the ROI and maintaining compliance. For this, use Pureview’s Activity Explorer. Also, routinely track Viva Insights and the Power Platform admin center reports. Using this, you can track agent ROI and usage frequency. Even the particular business processes are being successfully automated.
