The Hidden Risks In Wealth Platform Migrations

The best migration is the one your clients never notice. Clients should see the benefits, not the disruption. Wealth platform migrations rarely fail on conversion weekend. The cutover finishes, reports turn green and problems appear later once real activity begins. A tax lot shows the wrong cost basis. A sweep runs an hour late. An outside manager calls to ask why a trade file never arrived.

In my 22 years in wealth technology, I've found that the most serious migration risks are often the least visible. They're easy to miss during testing and only show up once the platform is live. Knowing where to look makes the difference.

Data Migration

Copying records from one database to another is the easy part. The real work is transforming them so they behave accurately under the new platform's business logic. That takes business transformation rules, and a business owner must sign off on each of these mapping/transformation rules.

Critical data includes client and account records, relationships, standing instructions, transactions, cash balances, positions and tax lots. Even a single tax lot migrated incorrectly can change a client's realized gain or loss—and with it, their tax obligation.

Complex instruments should be looked at more carefully. For mortgage- and asset-backed securities, check original face, current face and paydown factors. For Treasury Inflation-Protected Securities (TIPS), confirm the index ratio and inflation-adjusted principal. For pooled funds, verify units and unit values.

Configuration Migration

Every legacy platform holds years of settings: firm and region structures, users and entitlements, fee rules and schedules, ACH and wire cutoffs, sweep run times, corporate action recipients and approval thresholds. Most of it lives in the system, and very little of it is documented anywhere.

An inventory of such configurations should be prepared and compared line by line. Then decide what carries over, what changes and what goes away. Get entitlements wrong, and users can see client data they shouldn't, which is a regulatory problem. Miss one approval step, and a large transaction executes without sign-off.

Integration Risks

Integrations don't carry equal risk. I sort them into three groups. Core integrations, such as CRM, financial planning and trading systems, shape the advisor's working day. External manager integrations matter wherever a third-party manager holds investment authority. Models, trade files and position feeds must keep flowing, and many of these relationships are shared with the firm's clients, so a broken feed quickly becomes a client conversation.

Market data is the third group. Know which vendors will supply pricing, reference and corporate action data, and whether those feeds come ready-made or need new build and licensing work. For each integration, know the owner, the testing window and the client sensitivity. Engage third parties early; they have their own release schedules.

Success Factors

A migration isn't just a technology project. It changes how the firm operates. Firms that get it right give each area a clear owner and test through full processing cycles so that the platform is accurate and meets the firm's objectives before the go-live decision is made.
