Cloud Migration Assessment: Framework, Tools & Checklist
Cloud migration assessment is a structured review of a company’s IT environment. It helps decide which data should move to the cloud and how. The assessment reviews data volumes, users, permissions, folder structures, and file types.
The output is a migration plan firmly based on what your environment actually contains. It’s the same assessment process CloudFuze has used to move 100+ petabytes and more than 15 billion files to Microsoft 365 and Google Workspace.

How We Conduct a Cloud Migration Assessment: Step-by-Step Checklist
At CloudFuze, a cloud migration assessment begins with three things. The data, users, and the target cloud platform. Below is our checklist for a successful cloud migration assessment process.
1. Define Business Goals and Migration Needs
Before reviewing the data, we first set clear migration goals. For example, moving to Google Workspace or Microsoft 365 or consolidating cloud platforms. Next, we determine what will make the migration successful. For us, smooth migrations are characterized by:
- Data completeness
- Minimal workflow disruption
- Preserved permissions
- Meeting the migration timeframe.
2. Discover and Inventory the Source Data
Now, we find the places where your data resides. This can be Box, Dropbox, Microsoft 365, or another support platform. We check all content, such as folders, emails, chats, files, among others.
Finally, we record the amount of data and users. Huge migrations involve terabytes or petabytes of data. This impacts how we plan migration batches.
3. Review Data and User Relationships
Next, we review user permissions. It means who can access each type of content. We identify all aspects of user permissions, such as shared links, external shares and other access settings.
Then, we review the content structure. This involves looking at folder structures, timestamps file versions, and other metadata. This information allows us to establish what should be preserved on the target cloud platform.
This step ends with mapping users and content. We determine how source users and their content should be set up in Microsoft 365 or Google Workspace.
4. Choose the Migration Approach
Choosing a migration approach involves the following:
- Deciding whether the data will go to Microsoft 365, Google Workspace, or another supported destination.
- Determining what should be migrated and where it should go. We also decide how the migration should be divided into batches.
- Reviewing outdated or unnecessary content before migration. This reduces how much data needs to move.
- Deciding on the best way to handle shared links and other important context. CloudFuze Migrate works with CloudFuze Hyperlink Fixer to address broken hyperlinks during migration.
5. Review Security and Compliance
Cloud migration risk assessment is a core part of this review. We perform the following tasks during this assessment:
- Check permissions, external sharing, public links, and other ways sensitive data may be exposed. Then, we map what your regulators require. These include data residency, retention, and audit trails for HIPAA, FINRA, or GDPR rules.
- See to it that the migration process protects data while it is being moved. CloudFuze Migrate uses OAuth-based authentication and API-based migration to protect data during transfer. Our solutions follow security standards like GDPR, SOC 2 Type 2, and ISO 27001.
- Decide how data should be governed after the move. CloudFuze Manage can identify content sprawl, risky external sharing, and public links. It applies governance policies across the SaaS environment.
6. Plan Costs, Resources, and Timeline
Finally, we size the effort using data volume, user count, source and target platforms, and your migration needs. Timelines track data volume and permission complexity more than platform choice.
Thus, the pilot run establishes your actual per-batch rate before we commit to a full schedule. Large migrations are split into batches with a timeframe set per batch.
Then, we identify experts who will perform migration planning, testing, validation, and user communication. MSPs running this across multiple client tenants get per-tenant scoping and consolidated reporting.
When migration ends, we review SaaS usage, user access, and license needs. CloudFuze Manage provides visibility into each aspect of this ongoing management.
What Tools are Recommended for Performing a Cloud Migration Assessment?
Native utilities like the SharePoint Migration Tool or Google’s data migration service can inventory a single tenant. But they don’t report across platforms on permissions, versions, external shares, or link dependencies. This is exactly where we’ve seen large enterprise migrations actually fail. These three tools resolve such issues.
1.CloudFuze Migrate
CloudFuze Migrate helps enterprise IT teams move from assessment to execution within one migration workflow. Teams can scope users and data, plan migrations and test migration batches.
They can migrate files, emails, chats, and tenants, and validate results. All of this happens while preserving supported permissions, timestamps, versions, external shares, links, and comments.
2. CloudFuze Hyperlink Fixer
CloudFuze Hyperlink Fixer prevents broken links when moving content between cloud platforms. It helps keep critical links working during migrations to Microsoft 365 or Google Workspace.
3. CloudFuze Manage
CloudFuze Manage gives you clarity over your SaaS apps, users, licenses, and spend. It identifies governance risks such as content sprawl, public links, and external sharing. Thus, teams can address risks before and after migration.
Why Is Cloud Migration Assessment Critical for Businesses?
A cloud migration assessment delivers four things before migration actually begins:
Discover Migration Risks
An assessment spots complex permissions, incomplete data, and similar issues before migration. This prevents these issues from surfacing mid-move.
Plan Migration Costs
Migration costs are influenced by data volume and number of users. With an assessment, businesses get clarity into their migration requirements. They also get visibility into the resources needed.
Protect Data and Prove Compliance
A cloud migration risk assessment reviews permissions, sharing settings, and other things that can pose as data risks. It also documents the controls your auditors will ask about. For example, who had access to what, what was exposed publicly, and what was remediated before the move.
Prepare for the New Platform
An assessment gives clarity over how files, folders, and users, and permissions should be set up on the new cloud platform. Thus, the migration becomes more organized and easy to manage.
What Is a Typical Cloud Migration Assessment Framework and Its Key Components?
A cloud migration assessment framework has five components:
- Data Discovery and Inventory: Examines data on the source platform. This includes folders, files, permissions, versions, and other content. This step determines what needs to move.
- Data and Permission Mapping: Assesses how users, folders, files, and permissions are linked. It establishes how these relationships should work on the new cloud platform.
- Security and Compliance Assessment: Reviews permissions, external sharing, public links, and data residency or retention rules. It decides what must be remediated or locked down before content moves.
- Business Readiness: This part of the cloud migration readiness assessment framework decides if the organization is ready to move to Microsoft 365 or Google Workspace. It examines user needs, internal resources, and anything else that can pose an obstacle to the move.
- Migration Strategy: The insights from all the components above are used to create a well-rounded migration strategy. This includes setting priorities, choosing migration batches, defining the timeframe and the data which needs to move.
What Are the Common Pitfalls to Avoid During a Cloud Migration Assessment?
Cloud migration assessment services offered by leading providers like CloudFuze are built to prevent these six failures.
- Skipping Data Discovery: We do not start the migration without knowing what data exists. It’s critical to review files, folders, users, permissions, versions, and shared links first.
- Ignoring Permissions: We check how users access data on the source platform. Then, we plan how those permissions will work in Microsoft 365 or Google Workspace.
- Overlooking Data Quality: Old, duplicate, or unnecessary content can increase migration effort. We identify this content before deciding what to move.
- Ignoring Migration Requirements: Different data types need different migration plans. CloudFuze defines what needs to be preserved. This includes metadata, versions, comments, and links.
- Treating Migration as a One-Time Move: Our cloud migration analysis plan considers what happens after the move. CloudFuze Manage monitors SaaS usage and enforces data governance after migration.
- Skipping Migration Testing: Testing the migration before moving all users and data is critical for a smooth move. It identifies permission, data, and link issues early.
What Metrics Are Used to Evaluate the Effectiveness of a Cloud Migration Assessment?
We use the following metrics to measure migration readiness and planning accuracy:
| Metric | What It Measures |
|---|---|
| Data & Metadata Accuracy | 100% of in-scope files with versions, timestamps, and comments preserved |
| User Mapping Accuracy | 100% source-to-target match, zero orphaned accounts |
| Permission Accuracy | Permissions and external shares replicated exactly, no new public links |
| Migration Scope Accuracy | Final scope after assessing data volume and user count |
| Migration Errors | Zero unresolved errors at cutover, all pilot errors root-caused |
| Migration Speed | Every batch completes inside its planned window |
| Downtime and Data Completeness | Zero unplanned downtime, 100% of in-scope data transferred |
| Validation Results | Data, permissions, links, and mappings pass validation before cutover |
What Are the Next Steps After Completing a Cloud Migration Assessment?
After a cloud migration analysis, the plan executes in this order: executes in this order:
- Define the Migration Scope
Finalize the users, data, workloads, and metadata to migrate. - Map Users and Permissions
Map source users to their accounts in Microsoft 365 or Google Workspace. Confirm permissions and access. - Prepare the Target Platform
Set up user accounts, storage, sites, groups, and other required configurations. - Run a Pilot Migration
Test a small set of data first. Use the results to identify and fix issues early. - Migrate in Batches
Move data in planned batches. Use delta migration to capture changes made during the process. - Validate the Migration
Check data, metadata, permissions, links, and user access. Resolve issues before final cutover. - Complete Cutover and Post-Migration Checks
Move users to the new platform, provide support, and decommission the source when validation is complete.

Frequently Asked Questions
1. How Do I Prepare for a Cloud Assessment?
Start by defining your migration goals and scope. Review your source data, users, permissions, and collaboration structure. Identify what to migrate, archive, or delete. Check security and compliance needs. For Microsoft 365 or Google Workspace migrations, we use these findings to build a clear migration plan.
2. What Are the 7 Steps of a Cloud Migration Model?
The seven key steps are: pre-migration analysis, scope planning, user mapping, batch creation, pilot migration, one-time migration and validation, and delta migration and validation. The process then moves to cutover. Finally, post-migration integration is performed to complete the transition.
3. What Are the Key Steps to Include in a Cloud Migration Testing Checklist?
Test the migration with a small pilot batch first. Check data volume, file features, metadata, permissions, links, and user mapping. Test migration speed, errors, and security. Review the migration reports. Validate results before proceeding with the full migration to Microsoft 365 or Google Workspace.
4. What Are the Five Phases of Cloud Migration?
Assessment and discovery, migration planning, pilot testing, migration and validation, and cutover with post-migration integration. Steps 1 to 4 of the checklist above come inside phase one. Steps 5 to 6 produce phase two.
