Migration guide
Accounting practice management software migration
A practical guide for UK accounting firms moving from spreadsheets, inboxes, shared drives, or legacy tools into one trusted operating system.
Published 12 June 2026. Written for UK accounting and advisory firms planning a practice management software migration.
Five migration phases
Phase 1
Decide what becomes the source of truth
Agree which client details, contacts, entities, services, owners, documents, messages, deadlines, notes, and workflow history should live in the new system.
Phase 2
Clean active data before migrating everything
Start with active clients, open work, current owners, live deadlines, and useful documents. Archived history can be handled separately if it slows the first rollout.
Phase 3
Map old processes to new workflows
Convert inbox chasing, spreadsheets, task lists, and shared-drive folders into repeatable workflows for onboarding, document requests, reviews, approvals, and recurring jobs.
Phase 4
Pilot with messy real work
Test late client replies, missing documents, handovers, review comments, deadline pressure, and manager reporting before moving the whole firm.
Phase 5
Retire duplicate trackers
A migration fails quietly when the old spreadsheet stays alive. Retire duplicate trackers once the team trusts the new workflow and reporting layer.
What to migrate, archive, or rebuild
| Decision | Typical items |
|---|---|
| Migrate first | Active clients, contacts, entities, services, owners, open tasks, live deadlines, current document requests, and active workflows. |
| Review carefully | Historical notes, archived documents, old status labels, duplicate contacts, dormant clients, and inconsistent service names. |
| Keep archived | Records needed for reference but not daily work, especially if importing them would slow launch or create low-quality data. |
| Rebuild as templates | Recurring jobs, onboarding stages, review steps, approval flows, document request packs, and manager reports. |
Migration risks to control
Migrating too much bad data
Prioritise active clients and current work. Clean duplicates, owner fields, services, and deadlines before importing them into the new source of truth.
Recreating old spreadsheet logic
Use the migration to simplify workflows. Do not rebuild every old column, status, and workaround unless it still serves a clear operational purpose.
Managers do not trust reports
Make reporting part of the migration plan. Managers should test blocked work, deadline risk, client requests, and handovers before full rollout.
Clients get confused during changeover
Pilot client-facing requests with a small group first. Keep messages short, explain the new process, and avoid asking clients to use several systems at once.
Old tools stay in parallel
Set clear retirement dates for duplicate spreadsheets, inbox trackers, shared folders, and separate task boards once the new workflow is trusted.
Readiness questions before migration
- Who owns migration decisions inside the firm?
- Which client data is required for day-one operations?
- Which old fields, statuses, and documents are no longer useful?
- Which workflows should launch first?
- How will managers check work status after migration?
- What will clients experience during the changeover?
- Which old trackers will be retired and when?
- How will the firm measure adoption after 30, 60, and 90 days?

Frequently asked questions
How should an accounting firm migrate to practice management software?
Start by defining the new source of truth, cleaning active client data, mapping old processes to new workflows, piloting with real work, training managers, and retiring duplicate trackers after the team trusts the new system.
Should firms migrate all historical data?
Not always. Active clients, current work, deadlines, owners, and live documents usually matter first. Older records can stay archived or migrate later if importing everything would delay rollout or create messy data.
What is the biggest migration risk?
The biggest risk is importing old data and old habits without improving the workflow. A migration should make client status, document requests, deadlines, ownership, and reporting clearer than before.
How long does migration take?
Timing depends on firm size, data quality, workflows, and support. Many firms should plan migration as part of a staged rollout, starting with priority workflows before moving every service line and historical record.
