During an accounting platform migration from a legacy system like QuickBooks to a cloud-based ERP like Sage Intacct, the standard approach to data migration is to make sure it’s completed before your Go-Live date in the new system.  

Because of the severe financial, legal, and reputational consequences that can result from a delayed Go-Live, implementation teams often encourage companies to only migrate limited trial balance data along with their Open Accounts Payable (AP) and Open Accounts Receivable (AR) transactions from the legacy system.  

Some companies accept this compromise because of their fear of delaying their Go-Live, but it doesn’t have to be this way.   

At Platform Transition, we’ve developed a proven method for migrating historical accounting data before, during, and after your Go-Live (cutover) without creating duplicate transactions. This allows us to completely separate the activity surrounding the historical data migration from your cutover event and ensure that an incomplete data migration won’t be a roadblock to an on-time implementation. 

Let’s dive into how it works.  

A Two-Phase Data Migration That Supports Your Reporting Commitments on Day One 

At Platform Transition, we understand the importance of not missing your Go-Live cutover event, because we lived through our own version of that nightmare four times when we first transitioned from QuickBooks to Sage Intacct. In fact, that experience is what inspired us to pivot our entire business to focus on historical data migration to Sage Intacct.  

While our processes enable us to complete migrations much faster than in-house finance teams, we also know the risks that come with rushing to complete a historical data migration by an arbitrary deadline. It can lead to careless or strategic errors that end up either delaying the Go-Live or causing months of headaches from identifying and correcting erroneous data after the Go-Live.  

That’s why we developed a process that allows us to divide accounting data migrations into two phases. One phase moves all the data you need to continue operating your business in the new system as well as fulfill your reporting commitments by an agreed upon date on or around your Go-Live deadline. For many companies, this includes all of your Open AP and Open AR (and if you’re a construction company, it also includes things like Open Contracts, Open Commitments, Open AP and AR retainage), a cutover opening Trial Balance (if desired), and all the Master Data that supports your initial business operational and immediate reporting functions.  

The second phase moves the rest of your historical transactions into your target system, and it’s designed mathematically to be able to happen at any time, because our process carves up your data in a way that it prevents the introduction of duplicates, regardless of when or in what order we load each swathe of data.  

Go-Live Options in a GL Detail Migration 

When you partner with Platform Transition for The Multi-Dimensional Data Conversion Solution^™ (our take on a GL Detail Migration), you have a few options when it comes to migrating your Open AP/AR. Most VARs include some version of Open AP/AR migration in their implementation scope. If that’s the case for you, we can focus on your historical data only. Our proprietary processes allow us to migrate your historical GL transactions at any date without introducing duplicate transactions.  

However, we’ve also had many clients ask us to take on the migration of their Open AP/AR transactions, which lets them repurpose their VAR’s support hours to more training after Go-Live. 

Go-Live Preparation for a Subledger Migration 

We offer less flexibility for projects with The Simplified Subledger Conversion Process^™ scope (our Subledger Rebuild solution) because they are more complex, and the potential for error compounds when multiple vendors are involved in moving your data. We generally only take on a subledger migration if we’re responsible for migrating both the historical transactions and the Open AP/AR transactions.  

By the agreed-upon date on or around your Go-Live, we will:  

• Migrate all of your Open AP/AR transactions (and more for construction scopes)  
• Migrate all the Master Data tied to those open transactions 
• Create workarounds for any other critical reports tied to your funding or commitments 

We’re committed to making sure you can satisfy your reporting requirements at the earliest possible time in your implementation process. After your Go-Live, we’ll continue working to complete your historical subledger migration. 

If you’re not sure which migration scope is right for you, we’ve written a guide that outlines the differences between our GL Detail Migration and our Subledger Conversion.  

Our Process is Backed by Proven Migration Methods 

Platform Transition approaches data migration with a precise, transaction-level understanding of how accounting data behaves over time. We separate data based on whether that data is already existing or will be created in the future, and whether it’s paid or unpaid, and we control exactly when and how each category enters the system. We’ve developed proprietary data validation processes based on how the open and closed transactions create stability on the subledger. Those processes allow us to load data in stages without creating duplicates or distorting balances.  

The result is a Modular Go-Live supported by rigorously tested migration and QA processes, so each piece of your data lands safely, predictably, and exactly where it belongs. 

Eliminate the Risk of a Delayed Go-Live With Platform Transition 

A successful Go-Live depends on having the right data available at the right time. Platform Transition’s Modular Go-Live approach makes that possible by ensuring you have the data required to support critical reporting, audits, and day-one workflows by your Go-Live deadline, with the remaining historical data migrating later, if necessary. That approach removes unnecessary pressure from your implementation timeline and allows your VAR to focus on configuration, training, and adoption — without waiting on every last data set to be finalized. 

Our proven validation processes enable us to support aggressive timelines without sacrificing accuracy or completeness. The result is a predictable, on-time Go-Live backed by data you can trust. If you’re planning a Sage Intacct implementation and want a migration partner who designs for both speed and confidence, we’d love to help.
