Switching your broker CRM without downtime: the parallel-run playbook

Replacing a CRM feels risky because the CRM sits between your clients and their money. A parallel run removes most of that risk: both systems read the same trading server, and you switch only when they agree.

Phase 1: import

Bring over clients, trading accounts, approved KYC, documents and partner trees. Import trading accounts straight from the server too, so every account in the new system is linked to a real login. Keep each client's first-deposit date and partner attribution.

Phase 2: run in parallel

Point the new system at the same trading server, with a login limited to what it needs and demo groups first. Each day, compare:

• deposits and withdrawals booked,
• first-time depositors,
• partner commissions,
• open balances by brand.

Differences are useful: each one is either a bug to fix or a process to document before you switch. A daily reconciliation against the server does part of the work: a deposit booked through the old CRM shows up as a deal the new ledger doesn't know.

Phase 3: move the teams

Move one desk at a time. Finance first is often wise, because the approval rules are where systems differ most. Set up roles and brand access before people arrive, so day one is about work, not permissions.

Phase 4: switch the portal

Point your portal's domain at the new system. Send migrated clients a one-time link to set a new password, because passwords rarely leave the old system; nobody should have to register again.

When is it safe?

Switch when a full week of daily comparisons matches, the finance team has approved real requests in the new system, and you have a written rollback plan. Keep the old subscription until the first month end closes cleanly.
