A Clio migration is not successful merely because a CSV uploads. A law firm has to preserve the relationships among clients, matters, related contacts, activities, dates, responsible attorneys, and financial starting balances while avoiding the duplicate contacts and orphaned records that make the new system harder to trust than the old one.
Clio's current migration guidance draws a useful boundary. A standard migration can include contacts, matters, related contacts, tasks, notes, calendar events, emails, phone logs, unbilled time entries, summary accounts-receivable balances, summary trust balances, and scoped documents. It does not bring over detailed accounting history, historical bills, billed time, billable rates, reports, user permissions, or settings. Those exclusions should shape the firm's archive, cutover, and validation plans from the start.
The checklist below treats migration as a controlled legal-operations project. It gives the firm named owners, data rules, dependency-aware imports, a freeze procedure, evidence-based acceptance tests, and a clear line between records that belong in Clio and records that must remain available elsewhere.
Key decisions at a glance
- Decide which records belong in Clio and which historical financial evidence should remain in a read-only archive before anyone edits an export.
- Normalize contacts, matter identities, statuses, owners, practice areas, and custom-field values before they are copied into Clio templates.
- Import dependency records in the right order, keep template headers intact, and resolve importer errors from the returned error file.
- After the final legacy export, prevent untracked changes and validate representative matters before staff modify imported records.
- Rebuild permissions, rates, settings, integrations, and operating documentation because those items are outside a standard Clio data migration.
Set the Migration Perimeter and Clean the Source Records
Begin with a record-type inventory rather than a raw export request. For each source system, identify contacts, matters, related parties, open tasks, calendar events, notes, communications, documents, unbilled time, receivables, and trust balances. Mark the authoritative source for each type and document what will be imported, what will be reconstructed, and what will remain in a searchable historical archive. This prevents the firm from assuming that detailed financial history or legacy permission settings will appear in Clio when the standard migration excludes them.
Clean identities before mapping fields. Establish one canonical contact for each person or organization, preserve the source identifier in a controlled crosswalk, and review near-duplicates manually instead of relying on name similarity alone. Clio Manage does not offer a general bulk-edit function for contacts, and deletion or duplicate cleanup can have consequences, so an error prevented in the source file is cheaper than hundreds of individual corrections after launch.
Define the target matter model with the practice-area leads. Confirm matter descriptions, statuses, client links, responsible attorneys, practice areas, numbering rules, and the custom fields that staff will actually use. Create a field dictionary that lists the source column, Clio destination, allowed values, date format, blank-value rule, and owner. If the account has preconfigured fields or matter templates, reconcile those definitions before importing data so the same concept does not arrive under two competing fields.
- Record a disposition for every source data type: migrate, rebuild, archive, or retire.
- Resolve contact and company duplicates with a documented survivor record and source-ID crosswalk.
- Normalize matter status, responsible attorney, practice area, date, and custom-field values.
- Export immutable historical financial reports for transactions and bills that will not migrate.
Build Dependency-Aware CSVs and Prove a Staged Import
Use Clio's migration templates as contracts, not as flexible spreadsheets. Keep the provided column headers unchanged, match the documented formats exactly, remove unused example rows, and save the final files as CSV. Import contacts before matters so matter rows can link to the intended client. Other imports should use the exact matter display numbers, contact names, or active users required by the relevant template instead of informal labels that only make sense in the legacy system.
Run a staged import with a deliberately varied sample before moving the full population. Include open, pending, and closed matters; an individual and a company client; a matter with several related contacts; custom fields; an upcoming deadline; a completed task; an unbilled time entry; and matters with receivable or trust balances. The sample should expose mapping and dependency errors that a row-count comparison would miss, such as a valid matter attached to the wrong contact.
Treat importer errors as a repair queue with ownership. Download the error file, preserve the original row identifier, correct the source or mapping rule, and re-upload only after the same correction is applied consistently to the remaining data set. Track each exception by record type, cause, decision, resolver, and retest result. A falling error count is useful, but acceptance depends on accurate relationships and values, not a clean upload status by itself.
- Keep Clio template headers and documented field formats exactly as supplied.
- Load contacts before matters and honor the exact keys required by downstream templates.
- Test a representative set of real practice scenarios, not only easy or recently opened matters.
- Retain original files, corrected files, importer errors, and the resolution log as migration evidence.
Control the Final Export, Cutover, and Acceptance Review
Publish a cutover clock that everyone can follow. Clio warns that data entered into the previous system after the migration export will not be captured, so the firm must either stop using the source immediately after that export or maintain an approved delta-capture process that is reconciled manually. Tell attorneys and staff where to record urgent activity during the transition, who can authorize an exception, and when the legacy platform becomes read-only.
When production data arrives, validate it before routine work begins. Compare totals by record type, then sample matters across practice areas and offices. Open the contact, matter, related contacts, tasks, notes, calendar, communications, documents, and time entries for each sample. Reconcile the migrated receivable and trust starting balances to the signed source reports, recognizing that Clio receives summary balance line items rather than the underlying financial history.
Do not let users repair imported records while the acceptance review is still open. Clio notes that modifying imported data can prevent an import from being reverted if corrections are required. Route variances to the migration lead, preserve screenshots or record identifiers, and obtain written approval from operations, finance, and a practicing attorney before releasing the environment for normal use. The sign-off should list accepted exceptions and the system where excluded history remains available.
- Announce the final-export time, legacy-system freeze, emergency-entry method, and launch window.
- Compare source and target counts, but also inspect linked records and practice-critical dates.
- Reconcile summary receivable and trust balances against retained source-system reports.
- Prevent edits until the migration lead confirms whether a correction or reversal is needed.
Turn the New Clio Environment Into an Operated System
Migration acceptance is the point at which configuration work becomes operational. Recreate user roles, matter permissions, user and matter rates, settings, integrations, templates, notifications, and saved operating procedures under separate change records because they are not part of the standard data payload. Assign a business owner and technical owner for each integration before enabling it, especially where the connector depends on one person's account.
ALLMSP can coordinate the data workbook, secure file handling, workstation and identity readiness, cutover communications, validation evidence, and post-launch support queue while the firm's legal and accounting leaders retain authority over record meaning. That division matters: IT can prove that rows moved and permissions work, but the responsible attorney must confirm that a matter is complete and finance must approve balance treatment.
Schedule a stabilization review after users have completed real work in Clio. Examine duplicate contacts, failed imports, missing matter links, calendar discrepancies, document locations, time-entry ownership, access exceptions, and support tickets. Update the runbook with the fixes and named owners so the migration produces an environment the firm can administer, not a one-time transfer that becomes mysterious a month later.
- Rebuild excluded configuration under controlled change records and verify each setting.
- Assign business and technical owners for identity, documents, billing, and email integrations.
- Give users a single launch support channel with triage rules for data, access, and training issues.
- Review stabilization findings and close only when every accepted exception has an owner.

Frequently Asked Questions
What data can a standard Clio Manage migration include?
Clio's current overview lists contacts, matters, related contacts, tasks, notes, calendar events, emails, phone logs, unbilled time entries, summary accounts-receivable balances, summary trust balances, and documents subject to scoping and possible additional fees. The exact scope can vary, so the firm should confirm its source system and data volume with Clio before setting expectations.
Which records normally do not move into Clio through a standard migration?
Detailed accounting and financial history, historical bills, billed time entries, billable rates, reports, user permissions, and settings are outside the standard migration described by Clio. Preserve authoritative exports and plan separate configuration work rather than assuming those items will appear in the new account.
Why should contacts be imported before matters?
Clio's templates use contact identities to link matters to clients. Loading contacts first gives matter rows an existing record to match, which reduces orphaned matters and incorrect client relationships. Exact naming and required fields still need validation.
Can we change the column headings in Clio's migration templates?
No. Clio instructs firms not to modify the supplied headers because the importer maps those headers to destination fields. Populate the documented columns, follow the required formats, remove unused example rows, and save the completed file as CSV.
How should a firm handle work created after the final legacy export?
The safest plan is to stop using the source system immediately after export, as Clio directs. If urgent work must continue elsewhere, use one approved capture method, assign an owner, and reconcile every delta into Clio before launch sign-off. Informal notes scattered among staff are not a reliable cutover process.
How many records should we inspect after a Clio import?
There is no universal percentage that fits every firm. Use risk-based sampling across practice areas, offices, matter statuses, client types, record types, and financial-balance scenarios, and expand the sample whenever a defect appears. Counts alone cannot prove that relationships or dates are correct.
Why should users avoid editing imported data before acceptance?
Clio warns that changes to imported records can prevent the import from being reverted if corrections are necessary. Keep the environment under migration control, log discrepancies with record identifiers, and let the migration lead determine whether correction or reversal is appropriate.
How do we validate accounts-receivable and trust information?
Reconcile Clio's imported starting balances to signed reports from the legacy system at the same cutoff time. A standard migration uses a summary receivable line per matter and a summary trust balance per matter or contact, not the underlying transaction history, so retain the detailed source reports separately.
Should integrations be enabled before the Clio migration is accepted?
Usually they should wait until the data and ownership model are stable. Enabling email, document, or accounting connectors too early can create new records while the migration is still being corrected. Sequence each connector after acceptance with a named owner, test case, and rollback decision.
How can ALLMSP support a Clio migration for a law firm?
ALLMSP can help inventory source systems, protect exports, build data and exception workbooks, prepare identities and devices, coordinate cutover, test permissions and integrations, document validation, and run launch support. Attorneys and accounting leaders still approve legal-record completeness and financial treatment.
