Most TMS migrations look healthy at the end of week 1. Logins work, a handful of test loads moved through, dispatch is "trying it out." Then week 2 hits and momentum dies, drivers default back to the old system, accounting starts running both, and the project quietly slides into "we will revisit next quarter." This post lays out the five reasons a TMS migration stalls in week 2 and the fix for each, drawn from how carriers actually get fully live on an AI-native TMS.

The week 2 cliff is predictable, not random

Week 1 is novelty. The vendor's onboarding team is on calls, the leadership is engaged, and the team gives the new system the benefit of the doubt. Week 2 is when dispatchers, drivers, and accountants stop testing and start working, and any friction that has not been pre-solved becomes a reason to fall back.

Three signals tell you a TMS migration is about to stall:

• Dispatchers open the old system "just to check something" more than once a day

• Accounting is reconciling the same load in both platforms

• Drivers complain that the new app does not have a field the old one did

None of these are deal-breakers on their own. Stacked together inside the same week, they are how a $6K-a-month software contract turns into a $0 ROI six months later.

Fix 1: Load the historical data, not just the master records

Most migrations import drivers, trucks, customers, brokers, and a chart of accounts. They skip 24 months of historical loads, settlements, and invoices because "we have the old system if we need to look back." Two weeks in, accounting is back in the old system every day for receivables and dispatch is back for repeat-broker context.

Carriers who fully migrate import at least 12 months of loads with broker, lane, equipment, rate, and settlement attached. Datatruck's data migration workflow handles this with 99.9 percent accuracy and zero downtime, including the load history that prevents the fallback loop.

Fix 2: Pick the cutover date and kill access

The single biggest predictor of a stalled migration is leaving the old TMS turned on past the cutover date. The fix is unglamorous: pick a Friday, finish the parallel run, and remove dispatcher and accounting logins from the legacy system the following Monday.

Carriers worry this is risky. The opposite is true. Switching without losing a day of operations works because the cutover is decisive, not because both systems run forever.

Fix 3: Onboard dispatchers first, drivers second

Most TMS migrations train everyone at once. That is how dispatchers end up coaching drivers on a tool the dispatchers have used for four days. Train dispatch first, give them a week to get fluent, then onboard drivers with dispatch as the local expert.

The Datatruck dispatch board was refactored in 2025 and 2026 specifically because dispatchers are the power users. The enterprise dispatch board exists for a reason, and that reason is that fluent dispatchers carry the rest of the org.

Fix 4: Pick one workflow to nail before adding the next

The fleets that stall try to migrate every workflow on day one: dispatch, settlements, accounting, IFTA, factoring, driver pay, all at once. The fleets that succeed pick one workflow, prove it, then add the next.

1. Week 1: load creation through TruckGPT or AI Prompt

2. Week 2: dispatch board and driver assignment

3. Week 3: invoicing and factoring submission

4. Week 4: settlements and driver pay

5. Week 5: financial reporting and IFTA

Ray Cargo went from 50 to 350-plus trucks on Datatruck after a one-week onboarding because they sequenced workflows instead of flipping the entire fleet at once.

Fix 5: Make the AI lift the boring 60 percent first

The fastest way to make a TMS migration sticky is to remove the most-hated task in week 2. For most carriers that is manual rate-confirmation entry, manual broker email replies, or manual driver check-in calls.

Datatruck's AI stack is built for this exact moment. TruckGPT reads rate confirmations in seconds. AI Updater drafts the broker email and triggers driver check-ins. AI Dispatcher works the load boards. When week 2 hits, the dispatcher who just saved 4 minutes per load is not the dispatcher asking to go back.

What a stalled migration costs you

A stalled migration is not free. Most carriers pay both vendors for at least three months, watch operations spread across two systems, and lose the productivity gains they bought the new TMS for in the first place.

• Double software cost during the parallel-run extension

• Reconciliation hours across two ledgers

• Lost AI productivity gains until the new system is the only system

• Erosion of executive trust in the next migration decision

The fix is to commit to the cutover and lean on a partner that has run the playbook before. Datatruck's success stories show fleets running 100-plus trucks fully live in weeks, not quarters.

The week-2 health check

Run this check at the end of week 2. If three of the five answers are wrong, intervene immediately.

• Are dispatchers using the old TMS at all? Should be no

• Is accounting reconciling loads in both systems? Should be no

• Has the cutover date been set in writing? Should be yes

• Has the AI feature for the most-hated task been turned on? Should be yes

• Does the dispatcher team have one fluent power user? Should be yes

A clean week 2 is the difference between a TMS migration that pays off and one that quietly fails. If you want to see the Datatruck migration playbook on real fleet data, book a walkthrough.

FAQs

Why do most TMS migrations stall?

Most TMS migrations stall in week 2 because the old system stays on, history is not imported, and dispatchers fall back when friction hits. The fix is a decisive cutover, sequenced workflows, and AI features that remove the most-hated manual tasks early.

How long should a TMS migration take?

A mid-sized carrier with sequenced workflows can be fully live in 4 to 6 weeks. Carriers like Ray Cargo have onboarded in a single week, and PAVA Logistics ran a 200-truck rollout in two months. The variable is sequencing and cutover discipline, not platform speed.

Should we run two TMS systems in parallel?

Only for 3 to 5 days during the cutover. Leaving both systems live past that point is the single biggest reason migrations stall. Pick a Friday, finish parallel, and pull dispatcher and accounting logins from the old system on Monday.

What is the first workflow to migrate?

Load creation. If TruckGPT or the AI Prompt can turn rate confirmations into loads in week 1, dispatchers feel the productivity gain immediately and resist falling back. Settlements, accounting, and reporting follow once load flow is solid.
