Migration is a program, not a switch
MT4 and MT5 environments differ, and a migration can affect trading configuration, integrations, operations and client experience. Build an inventory before changing production.
Inventory dependencies
Map accounts, groups, symbols, plugins, CRM links, reporting, liquidity connectivity, websites, client cabinet and operational procedures.
Target MT5 architecture
Design the destination environment around current requirements instead of copying legacy architecture without review.
Integration migration
Validate each integration against supported MT5 interfaces and vendor versions. Replace assumptions with test evidence.
Testing and coexistence
A staged rollout may use parallel environments while teams test accounts, pricing, execution, reporting and support procedures.
Client transition
Plan communications, credentials, terminal access and support so the technical migration does not create avoidable client friction.
Next step
Build a requirements matrix covering platform scope, integrations, connectivity, hosting, security, support and ownership. This makes vendor proposals comparable and exposes missing dependencies before deployment.
