Cloud Migration Services in Brookhaven, GA: Microsoft 365 and Azure Migrations for DeKalb County Businesses

COMNEXIA has delivered managed IT and security services to metro Atlanta businesses since 1991, operating out of our Roswell, GA headquarters. Brookhaven businesses in DeKalb County, whether professional services firms off Dresden Drive or auto dealerships near I-285, face the same migration risk: moving email, file shares, and line-of-business applications to the cloud without losing data, breaking compliance controls, or leaving credentials exposed during the transition. We run cloud migrations as a structured, security-first project, not a weekend cutover that leaves your team troubleshooting on Monday morning.

What a COMNEXIA Cloud Migration Actually Covers

Our migrations center on Microsoft 365 and Microsoft Azure. For most Brookhaven businesses, that means moving from on-premises Exchange to Exchange Online, replacing shared drives with SharePoint document libraries and OneDrive for Business, and onboarding staff to Microsoft Teams for internal communication. Larger infrastructure workloads, including physical servers and virtual machines, move to Azure IaaS or Azure Virtual Desktop depending on your application requirements.

Every migration begins with an environment discovery: we inventory your current Active Directory structure, DNS records, MX routing, and existing mailbox sizes before a single account moves. That inventory determines whether we stage the migration in batches (typical for organizations with 50-plus mailboxes) or run a single-pass cutover (appropriate for smaller Brookhaven offices under 25 seats). We document each phase in a written migration runbook your team can review before go-live.

Identity Security Is Set Up Before the First Mailbox Moves

Rushing identity configuration is the most common cloud migration mistake. COMNEXIA configures Microsoft Entra ID (formerly Azure Active Directory) conditional access policies before migration begins. That means requiring multi-factor authentication for all users, blocking legacy authentication protocols such as IMAP and POP3 that bypass MFA, and scoping location-based access policies so that logins from outside Georgia flag for review. We also enroll endpoints in Microsoft Intune so that only compliant, managed devices can access Exchange Online and SharePoint after cutover. Configuring Intune compliance policies and deploying them through Entra ID conditional access takes place during staging, not after users are already live in the new tenant.

Dealership-Specific Considerations: FTC Safeguards and DMS Integrations

Brookhaven-area auto dealerships operating under the FTC Safeguards Rule (16 CFR Part 314, revised June 2023) must maintain documented access controls, encrypt customer financial data in transit and at rest, and produce audit-ready records of who accessed that data. A Microsoft 365 tenant migration directly affects all three requirements. COMNEXIA maps your dealer management system, whether CDK Global, Reynolds and Reynolds, or Dealertrack, against the new cloud environment before cutover to confirm that data flows remain encrypted and that service accounts holding DMS credentials are migrated into Entra ID with least-privilege role assignments rather than shared admin accounts. We also configure Microsoft Purview data loss prevention policies in your new tenant to flag or block outbound transmission of non-public customer information, which is an FTC Safeguards requirement your dealership cannot satisfy with inbox rules alone.

What Happens After the Migration Is Complete

Migration is not a hand-off. Once your Brookhaven team is live in Microsoft 365 or Azure, COMNEXIA folds your environment into our ongoing managed services stack. That includes:

• Patch management through NinjaOne, covering Windows endpoints, Microsoft 365 apps, and third-party software on a documented monthly cycle
• Endpoint monitoring and response using SentinelOne EDR, deployed to every managed device before migration cutover so protection is continuous through the transition
• Help-desk ticketing with a documented onboarding checklist specific to your new Microsoft 365 configuration, so your staff can reach support the first day they are live
• Monthly reporting that includes Entra ID sign-in anomaly summaries, Intune device compliance status, and patch completion rates your management team can read without an IT background
• Ongoing Entra ID access reviews to remove stale accounts and ensure former employees cannot authenticate against your tenant

Why Brookhaven Businesses Work with a Local Atlanta-Area MSP for Cloud Projects

Cloud migrations involve decisions that a remote vendor cannot make responsibly from a ticket queue. When your Brookhaven office's DNS cutover window opens at 11 p.m. on a Tuesday, you need an engineer who knows your environment and is reachable. COMNEXIA has supported metro Atlanta businesses for 35 years. Our team knows the Georgia business environment, has worked directly with DeKalb County area organizations, and will be here after the migration is complete because we manage your environment on an ongoing basis. We do not close a project and disappear.
