Office 365 Migration and Upgrade Services in Ann Arbor, MI

Modernize Your Ann Arbor Business Desktops Without Losing Data or Breaking Essential Applications

Office 2016 and 2019 Are No Longer Safe to Run

Microsoft ended support for Office 2016 and Office 2019 on October 14, 2025. Word, Excel and Outlook still open, but they no longer receive security fixes, which leaves every unpatched computer an easier target for malicious attachments and phishing. Many offices also run a mix of Office versions, so files break, macros fail and staff can’t collaborate smoothly. Viperspace Inc. provides Office 365 migration services in Ann Arbor, MI, moving businesses onto supported Microsoft 365 apps without disrupting daily work.

Since 2000, we’ve helped businesses across Washtenaw County keep their software current and secure. We review your licenses, test the add-ins and business applications that depend on Office, and roll out Microsoft 365 apps on a schedule that respects your deadlines.

This page covers upgrading Office desktop apps and licenses. Moving email, files or a whole organization into Microsoft 365? See our Microsoft 365 migration services.

Why Ann Arbour Businesses Make the Move to Managed IT

What Unsupported Office Software Is Really Costing You

Old Office versions rarely fail all at once. Instead, a client sends a file that won’t open correctly, a shared spreadsheet breaks because two people use different versions, or a new tax or legal application refuses to install on an old build of Office. For businesses in Ann Arbor, unsupported software can also raise red flags on cyber insurance questionnaires and client security reviews.

It’s time to plan your Office 365 migration when:

  • Office 2016 or 2019 Is Still Installed: These versions no longer receive security updates from Microsoft.

  • Your Office Uses Mixed Versions: Different computers run different releases, causing formatting and compatibility problems.

  • Licenses Are Hard to Track: Nobody is sure which product keys belong to which computers or former employees.

  • Business Software Requires a Newer Version: Vendors for accounting, tax or practice management software no longer support older Office releases.

  • Windows 10 Machines Are Still in Use: Windows 10 also reached end of support on October 14, 2025, so many offices need to plan both upgrades together.

Subscription Office Changes How Your Business Stays Secure

Moving to Microsoft 365 apps changes how Office is licensed, updated and secured. Instead of buying software once and running it until it breaks, each user receives continuous security patches and new features through a subscription tied to their account.

That shift is an opportunity. We use the upgrade to clean up old licenses, standardize settings across every computer, and turn on protections such as multifactor authentication for every account.

The result is an office where everyone runs the same secure, supported version, and nobody has to wonder which computer still has the old software.

Office Upgrade Priorities for Firms in Ann Arbor

  • Tax and Accounting Firms: Upgrades must avoid tax season and keep Excel add-ins and client portals working.

  • Law Practices: Document management systems, templates and Word add-ins need testing before any change.

  • Older Computers: Machines that can’t run Windows 11 may need replacement alongside the Office upgrade.

  • Budget Planning: Subscription licensing shifts Office from a one-time purchase to a predictable monthly cost.

Office 365 Upgrade Questions From Local Businesses

Can we keep using Office 2016 or Office 2019?

The programs will still open, but Microsoft stopped releasing security updates for them on October 14, 2025. Continuing to use them increases security risk and may cause problems with insurers, clients and newer business software.

Will our templates, macros and add-ins still work after the upgrade?

In most cases, yes, but they should be tested first. We check custom templates, macros and third-party add-ins with a small group before upgrading the whole office.

What is the difference between Office 365 and Microsoft 365?

Microsoft renamed most Office 365 business plans to Microsoft 365 in 2020. Today, Microsoft 365 plans include the desktop Office apps plus cloud services such as Teams, OneDrive and Exchange Online, depending on the plan.

Do we have to move our email at the same time?

No. You can upgrade Office desktop apps first and move email later, or do both together. If you also need email or files migrated, our Microsoft 365 migration team can plan both projects together.

Do Microsoft 365 apps still work on Windows 10?

Microsoft has said it will continue providing security updates for Microsoft 365 apps on Windows 10 until October 2028, but Windows 10 itself is no longer supported. We recommend planning a Windows 11 upgrade alongside your Office migration.
