“Garbage in, garbage out.” – George Feuchsel
It’s one of the most well-worn phrases in technology – and for good reason.
Because when it comes to legal tech implementation, this one truth holds firm:
Your platform is only as good as the data that powers it.
In Chapter 11 of Beyond the Features, I focus on one of the most overlooked – and most critical – components of a successful legal tech rollout: data migration.
It’s not glamorous. It’s not exciting. But it’s foundational.
And too often, it’s rushed.
Shiny Tech Can’t Save Dirty Data
Firms will spend months selecting a new system – mapping features, sitting through demos, negotiating pricing. But when it comes to preparing the data that will actually feed that system, shortcuts appear.
Outdated records get lifted across.
Duplicate matters and contact profiles sneak in.
Inconsistent field formats are ignored.
Suddenly, that powerful new platform feels clunky, confusing, and underwhelming from day one.
The reason? Tech can’t fix bad data – it only makes it more visible.
The Cost of Skipping the Clean-Up
Poor data quality doesn’t just make your new system harder to use – it undermines trust.
Reports get questioned. Workflows break down. Teams resort to workarounds. Adoption drops. And the credibility of the entire transformation effort takes a hit.
On the flip side, firms that prioritise data cleansing before migration enjoy:
Smoother go-lives
Faster adoption
More meaningful dashboards and insights
Fewer user complaints
And better ROI – because the system can do what it’s designed to do
Clean data is not just about accuracy. It’s about performance, confidence, and the ability to use your technology strategically.
Set the Stage for Success
Data preparation isn’t simply a technical task – it’s a strategic investment. It requires:
Clear ownership and accountability
Time and budget allocated for review and correction
Alignment between practice teams and IT
A plan for what gets migrated, what gets archived, and what gets left behind
This is where many firms benefit from external support. Not just to manage the migration, but to provide the structure, perspective, and discipline to get the data right before the first line is imported.
Because once the system is live, cleaning up is harder – and messier.
