Migration

Moving in, without the cliff edge.

Most firms do not switch systems on a weekend. They move the live matters first, keep the old system readable, and let the archive follow at its own pace. This is how that works in practice, including the part everyone worries about: client money.

What moves, and what stays

Nothing is deleted, and nothing is held hostage

Moves into OpenLPM

  • Clients & contacts — with identifiers, billing details, referral sources and intermediaries.
  • Open matters — the priority. Each one mapped to the right practice area and blueprint.
  • Documents — folders and files attached to their matters, with the executed copies identifiable.
  • Client money balances — as dated opening balances, proved by a reconciliation (§ below).
  • Firm knowledge — templates, clauses, procedures, rate cards and fee schedules, rebuilt as the firm’s own blueprints.

Stays where it is

  • The old system, readable, for as long as you keep paying for it. Closed files can be looked up there until you decide otherwise.
  • The historical archive, by default. Ten years of closed matters move on request, in batches, or not at all.
  • Your existing accounts, if you prefer. OpenLPM can record the operational ledger without replacing your accountant’s system of record — decide that with them.

There is no exit fee for taking your data out, in either direction, at any time.

The phases

Four phases, typically four to six weeks

Deliberately unhurried. Firms that rush the mapping spend the saved week fixing duplicates afterwards.

PhaseWhat happensTypical durationWho leads
1 · Discovery & mappingExport from the current system; map fields to OpenLPM; agree what counts as a client, a matter and a duplicate; identify the trust cutover date3–5 daysOpenLPM + firm administrator
2 · Configure the firmPractice areas, matter numbering, procedure blueprints, templates and clauses, fee schedules, roles, time rules, notification settings1 week (parallel to phase 1)Firm, with us advising
3 · Move in batchesClients, then open matters, then documents, then balances — each batch reviewed and signed off by the firm before the next begins1–2 weeksOpenLPM, firm reviews
4 · Parallel run & cutoverBoth systems live for one month; staff work in OpenLPM, the old system stays readable; trust reconciled on the cutover date; old subscription ends when you say2–4 weeksFirm, with us on call
The part everyone worries about

Client money, moved on a stated date

Balances are not “synced”. They are opened on a dated cutover, then proved — which is precisely what a trust account should look like.

  • A stated cutover date. Every client balance is opened with the same effective date, so there is a single point at which one system stopped and the other started.
  • Opening entries, not balances keyed in. Each opening balance is an entry with a reference to the old system’s record, so it can be traced back.
  • A reconciliation that proves it. The bank statement on the cutover date is reconciled against the new ledger; the total must agree before the old system is retired.
  • One month of dual visibility. Inbound client money is recorded in both systems during the parallel run, so nothing lands in a gap.

Documents

What to move first, and what can wait

Move first — the working set

Documents attached to open matters, current precedents and templates, and anything a client might ask for this month. This is usually a small fraction of the total archive.

Move next — recent history

Closed matters from the last two to three years, in batches, as staff have time. Naming conventions are cleaned during the move, not afterwards.

Move on demand — the deep archive

Older material stays in the old system or an export until there is a reason to bring it across. Moving everything “just in case” is how migration projects fail.

Common issues

The five things that actually go wrong

None of these are surprising, and all of them are cheaper to plan for than to discover.

IssueWhy it happensWhat we do about it
Duplicate clientsYears of “Mr Patel”, “Patel, R.” and “Patel Holdings” entered by different peopleDuplicates reported during mapping and merged with your approval before matters are attached
Inconsistent matter numberingThe old system allowed manual references, or several formats over timeOld references retained as a searchable field, new references generated to your new convention
Missing documentsFiles referenced in the old system that were never uploaded, or live on someone’s desktopA missing-document report per matter, so the gap is visible and can be closed before go-live
Fee history that cannot be reconciledHistoric billing recorded inconsistently, or in a second systemHistoric invoices imported as records for reference; the new ledger starts clean at the cutover
Mid-matter trust balancesClients with funds held across several live mattersBalances opened per client, with the matter allocation agreed with the firm where the old system did not split them

What you get from us

A migration plan with your name on it

A written plan covering the four phases, the cutover date, the batch schedule and who signs off what. It becomes the document your partners read before agreeing to move.

  • Mapping workbook — every field from the old system, and where it lands.
  • Batch sign-off records — what was reviewed, by whom, on what date.
  • Cutover reconciliation — old total, new total, and the statement that proves both.
  • An exit route — you keep a complete export of everything at every stage, including if you change your mind.
