Great Plains Migration · Microsoft Business Central
GP Support Has Ended.
Your Migration
Doesn’t Have to Be Hard.
Microsoft ended mainstream support for Dynamics GP. The clock is running, and the longer you wait, the higher the risk. TechWise Group has a proven GP-to-Business Central migration path that preserves your full financial history, replaces every report, and goes live in 90–120 days without operational disruption.
GP Support Has Officially Ended
Full Historical Data Preserved
90–120 Day Go-Live Standard
Zero Operational Downtime at Cutover
The Cost of Waiting
Every Month on Unsupported GP
Is a Month of Compounding Risk.
This isn’t a hypothetical. These are the specific, documented risks that apply to every company still running Great Plains today.
Unpatched Security Vulnerabilities
Microsoft no longer releases security patches for GP. Known vulnerabilities accumulate with no fix coming. Your ERP, the system with your most sensitive financial data, is exposed.
Active risk, no patch cycle
Compliance Documentation Gaps
GP’s audit trails were not built for modern SOX, HIPAA, or FDA compliance standards. Without active Microsoft support, there is no path to close these gaps, only workarounds that grow more fragile over time.
SOX · HIPAA · FDA · CMMC exposure
Integration Breakage
Every Microsoft 365 update, Azure change, or third-party API update is a potential GP integration failure, with no Microsoft support to fix it. Your connections to the rest of your stack become increasingly brittle.
No Microsoft support for breakage
Escalating Maintenance Costs
As GP ages without official support, the cost of keeping it running rises, custom maintenance, third-party patches, consultant fees for issues that should be covered by a vendor. The economics worsen every quarter.
Cost compounds each quarter
Shrinking GP Expertise
The pool of qualified GP consultants is contracting as the platform ages out. The partner who maintains your system today may not be available in 18 months, and finding a replacement will be harder and more expensive.
Talent market narrowing
Audit and Transaction Risk
If your company is heading toward a sale, PE investment, or external audit, an unsupported ERP is a significant diligence flag. Buyers and auditors view GP’s end-of-life status as a liability, and they’re right.
M&A and audit diligence exposure
The question isn’t whether to migrate. Microsoft answered that. The question is whether you migrate on a planned 90-120 day timeline, or in an emergency when a security incident, a failed integration, or an audit forces your hand. The difference in cost, disruption, and risk is significant.
Tell Us If This Sounds Familiar
You Already Know GP’s Days
Are Numbered. Here’s What We Hear.
Every GP company we talk to is already living with the consequences of running on an unsupported platform. The pain is real, but so is the path out.
“We’ve been “planning to migrate” for two years. Every time we scope it, the project feels too big and we push it another quarter. I know we can’t keep doing that.“
CFO, $65M Manufacturer, Chicago
“Our GP consultant told us last month he’s winding down his GP practice. He’s the only person who knows our customizations. I felt the urgency for the first time.“
Controller, $42M Distributor, Philadelphia
“We’re in a PE-backed portfolio company. Our sponsor just flagged GP’s end-of-life in a board deck as a risk item. The pressure to move is real now.“
VP Finance, $110M Multi-Entity Company
“GP broke our Microsoft 365 integration last month after an Office update. We’re patching it manually. Our IT guy said it’ll happen again and he doesn’t know when.“
CFO, $55M Food & Beverage Company, Los Angeles
Your Data Is Safe
Your Full GP History Comes With You.
Nothing Gets Left Behind.
The fear of losing years of financial history is the most common reason GP companies delay. Here’s exactly what we migrate, and how every balance is validated before you retire GP.
Full Transaction History
Every posted GP transaction: invoices, payments, journal entries, payables, migrated and reconciled to your final GP trial balance. Your historical P&L is intact and auditable from Day 1.
Open AR & AP Balances
Open invoices and unpaid bills migrate with full aging intact. Your AR and AP aging in Business Central on Day 1 matches your final GP reports exactly, down to the penny.
Chart of Accounts, Rebuilt
We don’t copy your GP COA. We redesign it for the dimensional reporting, cost center visibility, and consolidation structure your business actually needs going forward.
Customers, Vendors & Master Data
Every customer and vendor record, payment terms, credit limit, and relationship history migrates and is deduplicated. Your team doesn’t start over on 10 years of master data.
SmartLists & Reports, Replaced
Every GP SmartList and Management Reporter report is inventoried in discovery. Each one is rebuilt in Power BI or Business Central’s native reporting engine, with significantly more capability.
Integrations & Third-Party Connections
Every GP integration is audited before the project starts. Most have Business Central equivalents, frequently better ones. Nothing is left as a gap at go-live. Your integration audit is an early deliverable.
Reporting Replacement
Management Reporter and FRx
Don’t Just Get Replaced. They Get Upgraded.
Reporting is the most common concern in a GP migration, and the area where Business Central creates the biggest uplift. Here’s exactly what replaces what.
What you have in GP today
Management Reporter / FRx
✕ Static row/column report definitions
✕ Manual export to Excel for board packs
✕ No real-time data, requires manual refresh
✕ No drill-down to transaction level
✕ FRx is fully unsupported and end-of-life
✕ Limited visualization, text tables only
✕ No mobile access or self-service capability
What you get in Business Central
Power BI + Native BC Reporting
→ Live dashboards connected directly to BC data
→ Board packs generated automatically, no exports
→ Real-time data, always current, always reconciled
→ Full drill-through from summary to transaction
→ Actively developed and Microsoft-supported
→ Charts, KPI tiles, trend lines, full visualization
→ Accessible on any device, desktop, tablet, mobile
Every Management Reporter and FRx report is inventoried in discovery. We document who uses each one, how, and what business decision it drives. Each report gets a Power BI equivalent built and validated before go-live, so your team lands on better reporting, not just different reporting.

Before you commit to anything, TechWise delivers a complete GP End-of-Life Readiness Assessment, risk flag analysis, data inventory, integration audit, report catalog, compliance gap review, and a fixed timeline and cost range.

Why TechWise for This Migration
We’ve Done This Migration.
Many Times. Here’s What Makes It Different.
GP migrations fail when partners underestimate the reporting complexity, mishandle the data transformation, or skip the parallel run to save time. We don’t do any of those things.
01
Former Controllers on Every Project
Our migrations are led by accountants who have closed the books on a GP company. They know which SmartLists your controller can’t live without, which Management Reporter trees matter, and what breaks in the first close on a new ERP.
02
The Reporting Gap Is Our Specialty
Management Reporter and FRx replacement is where most GP migrations fail or disappoint. We inventory every report, rebuild each one in Power BI, and validate them with your team before go-live. Nobody discovers missing reports after cutover.
03
Your Budget Model. Zero Surprises.
Fixed-Fee or Time & Materials, you choose. The two-week migration plan we produce before any commitment gives you a precise scope. No “unforeseen complexity” invoices. No scope creep surprises at go-live.
04
The Parallel Run Is Non-Negotiable
We run both GP and Business Central simultaneously until your finance team trusts every number. Most partners shorten or skip this step to hit their timeline. We don’t, it’s the only way to guarantee zero disruption at cutover.
05
Compliance Rebuilt from Day 1
SOX, HIPAA, FDA 21 CFR, CMMC, built into the Business Central architecture before go-live. The compliance gaps that GP’s end-of-life created get closed properly, with audit-ready documentation prepared before your auditors arrive.
06
We Stay After Go-Live
Quarterly Business Reviews with a live Power BI ROI dashboard. Your first close in Business Central will be shorter, cleaner, and more auditable than your last close in GP. We make sure of it.

“We’d been on GP for 11 years and had been ‘planning to migrate’ for three of them. TechWise delivered a readiness assessment in less than a week, and it was half the scope we’d been quoted before. We went live in 16 weeks. Our first close was 5 days. Our auditors didn’t flag a single issue. I wish we’d done it two years ago.”
