Exchange mailboxes
Mail, folders, calendar, contacts, tasks and rules, with categories, retention tags, archive and folder permissions. Source from Microsoft 365 or on-prem Exchange 2016 and 2019.
Microsoft 365 & on-prem migration
Migrate Exchange, SharePoint, OneDrive and Teams with full fidelity.
AEUMIG moves your Microsoft 365 and on-prem Exchange and SharePoint workloads between tenants or in hybrid setups. Your content is used only to run your migration. It is not kept afterward, and it is never mined, reused, or sold.

What AEUMIG moves
Every core Microsoft 365 workload, moved with fidelity.
Source from Microsoft 365 or on-prem, target Microsoft 365 or hybrid. One tool for mail, files, sites and collaboration.
SharePoint sites and libraries
Site structure, subsites, lists, libraries, files, versions, metadata columns, content types, permissions and navigation, moved via the SharePoint Migration API for speed.
OneDrive for Business
Per-user drives migrated cross-tenant, with target drive provisioning, sharing links re-issued and version history preserved.
Teams
Teams and channels, standard, private and shared, plus channel messages, files, tabs, apps, members and roles, imported in Teams migration mode.
Cross-tenant and hybrid
Move Microsoft 365 tenant to tenant, or run hybrid with on-prem Exchange and SharePoint in the path.
Delta and incremental sync
A bulk pass followed by a delta pass keeps source and target in step, with a continuous delta mode and a short final-delta cutover window.
Throttling-safe
Respects Microsoft Retry-After and throttling headers with configurable per-mailbox and per-tenant concurrency caps, so large moves stay stable.
Reporting and audit
Job history, item-level drill-down and error analytics, with resumable items and PDF, CSV and JSON export.
Microsoft 365 Health & Security Assessment
Scan the tenant before you migrate.
AEUMIG audits the security posture of a Microsoft 365 tenant across identity, Exchange, SharePoint and OneDrive, Teams, Intune and Defender, plus a licensing and feature-utilization review. Every finding carries a severity, the evidence, a plain-language reason it matters, concrete remediation steps, and a portal deep-link alongside the Microsoft documentation.
Identity
MFA coverage on privileged accounts, conditional access and sign-in posture.
Exchange
Mail flow, mailbox size ceilings and transport rules that can block a move.
SharePoint & OneDrive
Tenant-wide external sharing, orphaned sites and content prerequisites.
Teams
External federation and guest access reviewed before Teams import.
Intune
Device compliance and management posture read across the tenant.
Defender
Threat protection policies checked so gaps do not reach the target tenant.
Microsoft Secure Score
Secure Score controls are pulled live from the tenant, so every rule reflects the current control state rather than a cached snapshot.
CIS Microsoft 365 Benchmark v3.0.0
About 40 rules across all workloads, each citing its exact CIS section, mapped to the tenant configuration.
Migration-readiness rules
AEUMIG-native checks for blockers such as orphaned sites, mailbox size ceilings, Teams external federation and mapping-coverage prerequisites.
Licensing hygiene
Unused SKUs, disabled service plans, duplicate assignments and underused E5 workloads surfaced for review.
Run it in migration-readiness mode to catch blockers before they reach the destination, or in audit-only mode with a read-only scope on a tenant that will never be migrated. Reports export as PDF, JSON or CSV; the PDF opens with a plain-English executive summary, then per-workload technical finding cards.
Why AEUMIG
Your data stays yours.
A migration tool touches everything in your tenant, so privacy comes first. AEUMIG uses your content only to run your migration. It is not kept afterward, and it is never mined, reused, or sold.
- Used only for your migration. Your mail, files and messages are moved to your target and are not retained by AEUMIG once the job is done. We do not mine them or share them with anyone.
- No passwords to hand over. AEUMIG connects through Microsoft's own secure app permissions, so nobody's password is ever collected or stored.
- Private end to end. Everything is encrypted in transit and at rest, and connection details are used only to run your migration, never kept a moment longer than needed.
Trust posture
Full visibility, always.
- A clear record of every action. You get a complete, tamper-evident history of what was moved and when, so there are no surprises and nothing to reconstruct after the fact.
- You decide who can do what. Simple roles for viewing, operating and auditing, with a second confirmation required before anything is deleted or overwritten.
- Nothing kept afterward. Once your migration is done, your content and your connection details are removed. We do not hold onto your data or reuse it.
How it works
Five steps from enrollment to cutover.
A clear path: connect the tenants, assess, map identities, migrate in passes, then cut over with a short final delta.
1
Enroll a tenant
Add a source or target tenant: name, cloud or on-prem, credentials, test the connection, then save it encrypted.
2
Assess
Run the Health and Security Assessment and a discovery scan to inventory items, sizes and blockers before anything moves.
3
Map
Match source identities to target by primary SMTP, plus URL, permission and content-type mappings, validated before a job can start.
4
Migrate
Provision the target, move items in a bulk pass, then a delta pass, with live progress, resumable items and per-item error tracking.
5
Cut over
Pause source writes, run a final delta, follow the MX and DNS guidance, then unlock the target, with a two-factor prompt on cutover start.
