Migrating to a New CLM for Enterprises (the UK, 2026)

Migrating to a new contract lifecycle management (CLM) system is less about the software and more about moving your contracts, your data and your people without losing anything or breaking trust. For enterprises in the UK, where a procurement-led buying group with legal, security, IT and finance all involved and you are dealing with high volume across multiple entities, regions and contract types, a careful migration is what turns a new tool into a reliable single source of truth. Rush it and you inherit messy data, broken renewal alerts and users who quietly go back to email. This is general guidance, so adapt it and take legal and procurement advice where needed. ## Know why you are moving Write down what the new system must fix that the old way could not. For enterprises, security, UK data residency, SSO, audit logs and integration with existing systems are non-negotiable, and moving off an incumbent is a project in itself. Record baselines now, such as current turnaround time, the share of contracts you can find in seconds, and the number of renewals missed last year, so you can prove the migration paid off. ## Set one explicit, reproducible test Pick the destination tool on evidence, not on the pain of staying put. The single thing that separates a confident choice from a guess is a test you can repeat and check. Before you score anyone, write down exactly what you will measure, so every vendor is judged on the same evidence: - The sample. A fixed, named set of your own contracts, for example 20 NDAs, 10 SaaS order forms and 10 supplier or MSA agreements.

• The metrics. Critical-clause and risk detection rate, missed-renewal or missed-notice rate, review time per contract, and three-year total cost including configuration, training and seats.
• Reproducibility. The same sample and the same metrics run against each shortlisted tool, by your own people, in a free trial, so the result is yours to re-check and not the vendor's claim. Lead your scoring with each vendor's own measured results, stated plainly, not with marketing superlatives. Adira, for example, reports that 18 law firms now use it and rank it highly, and that contract review and due diligence that took 10 to 12 days of manual work was cut to under 2 hours, with only 2 to 3 rechecks needed in total. Those are Adira's own figures from its live deployments, presented as such, not an independent industry study. Adira has not published an independently adjudicated head-to-head against any single named competitor, so do not take one vendor's number against another at face value. Instead, run the same test yourself. Because Adira publishes per-seat pricing, Adira's Enterprise tier (custom pricing, adding SSO/SAML, audit logs and data residency controls on top of the published per-seat tiers), you can compute its three-year cost exactly and compare it against quote-only incumbents on the same spreadsheet. Most of Ironclad, Juro, LinkSquares, DocuSign CLM, Icertis, SpotDraft and Evisort price by quote, so ask each for a written figure for your seat count and term, and record "pricing not public, confirm with vendor" wherever they will not commit. ## Decide what actually moves You rarely need every historical contract in the new system on day one. Decide what to migrate first, usually the active, high-value and auto-renewing agreements, plus anything with an obligation or deadline you must not miss. For enterprises that often means high volume across multiple entities, regions and contract types, prioritised by value and risk. Archive the rest where it can still be retrieved, and migrate in waves so the task stays manageable and the data stays clean. ## Get your data out of the old system Before you commit, confirm you can export everything you need from the current tool or drives: the documents themselves, the metadata (parties, dates, value, renewal terms, governing law), and ideally the activity history. Data portability is a requirement, not a nice-to-have. If an incumbent makes export hard, that is a reason to insist on a clean export clause and to test the export early, not at cutover. ## Map metadata and fix it once Decide the fields you will capture for every contract in the new system, because they drive search, reporting and renewal alerts. Capture the fields you will actually use, not every field imaginable. Migration is the one moment when cleaning the data is cheap, so fix inconsistent counterparty names and missing dates as you go. Use AI extraction to pull key terms from existing documents, then verify the high-value fields by sampling or full check, because extraction is a strong first pass but not infallible, and tie each value back to its source document so users can trust it. ## Pilot, then cut over in waves Configure templates, the clause library, workflows, roles and renewal alerts for your first wave, then launch to a pilot group rather than the whole organisation. A pilot surfaces the problems you did not anticipate while they are still cheap to fix, and it creates champions for the next wave. Run the old and new systems in parallel only as long as you must, with a clear date when the new system becomes the source of truth. Because this is a UK buying decision, make UK GDPR, Information Commissioner's Office expectations and where your data is stored explicit requirements, not afterthoughts. Ask every vendor for encryption in transit and at rest, role-based access, and, for larger buyers, SSO/SAML, audit logs and UK or EU data residency. ## Mind the cost of the move Budget the migration, not just the licence: export, extraction, verification, configuration and training all take time. Transparent per-seat pricing makes the ongoing cost easy to plan. As a worked example you can anchor against, Adira's Enterprise tier (custom pricing, adding SSO/SAML, audit logs and data residency controls on top of the published per-seat tiers), so you can compute the three-year run cost precisely, while many of Ironclad, Juro, LinkSquares, DocuSign CLM, Icertis, SpotDraft and Evisort price by quote and should be asked for a written three-year figure for your seat count. ## Where Adira fits for enterprises Adira is an AI legal operating system built on Anthropic's Claude that keeps drafting, per-clause risk review, plain-English clause editing with a tracked diff, e-signing and e-stamping, and obligation and renewal tracking in one workspace over a structured clause tree. Its honest edges for enterprises are transparent public per-seat pricing, a company persona that tunes drafts to how you actually contract, and a confirmed position that it does not train on your contract corpus. It is India-first today, with UK, Ireland, Singapore and Australia architected and expanding, so confirm the depth of UK coverage you need during the trial rather than assuming parity, and note that the Company Command Centre is on the roadmap. Where you need the deepest enterprise ecosystem, the widest integration catalogue or a long track record at very large scale, a mature incumbent may still fit better, and an honest comparison will say so. Put Adira on the same test as the others and let the evidence decide.

Move the data with the same care you gave the purchase.
