Start with the destination, not the old tool
Before comparing plans, define what the new CRM must do. List must-have fields, pipelines, reports, automations, integrations, user roles, and retention needs. Separate 'nice to have' from 'needed on day one.' For a small business, a useful test is whether a record can answer: who is the customer, what did they buy, what happens next, and who owns the follow-up? If the old system has years of notes, decide which notes are legal records, which are useful context, and which are clutter. This scoping step turns migration from a vendor promise into a measurable plan. It also helps homeowner-facing businesses that use a CRM for quotes, service history, and consent records. Check local privacy, tax, and record-keeping rules with qualified local advice where relevant.
Map data by decision value, not by habit
Not every field deserves to travel. Create a simple table: source field, destination field, data type, required?, owner, cleanup rule, and acceptance test. Mark fields as keep, transform, archive, or drop. Transform examples include splitting full names, normalizing phone formats, standardizing country/state values, and converting free-text statuses into picklists. Archive old attachments or emails if they are not needed daily. For consent and marketing preferences, preserve the exact basis and date if your process relies on them; otherwise seek local advice. The goal is a migration plan you can explain to a non-technical colleague in five minutes. If you cannot explain why a field is moving, it probably should not move on day one.
Compare migration plans on six practical criteria
Ask each vendor or consultant to show the same six things in writing. (1) Scope: which objects, fields, attachments, notes, and history are included. (2) Method: template import, API, staged migration, or manual re-entry, plus who does what. (3) Validation: record counts, field-level checks, sample reviews, and sign-off steps. (4) Downtime and cutover: when the old system becomes read-only and how rollback works. (5) Security and access: encryption, permissions, deletion, backups, and handling of personal data. (6) Cost structure in USD: fixed fees, hourly work, storage, add-ons, and internal staff time. Avoid comparing only headline fees. A cheap import that needs weeks of cleanup can be the more expensive plan. Ask for assumptions and exclusions in plain language.
A small hypothetical example with assumptions
Suppose a two-person home-services business has 4,000 contact records, 1,200 quotes, and 900 service notes. Assume 30% of contacts are duplicates, 15% have missing phone numbers, and the owner wants three years of history in the new CRM. Plan A is a basic CSV import quoted at a hypothetical $600 plus 20 internal hours. Plan B is a staged migration with cleanup and validation quoted at a hypothetical $1,800 plus 8 internal hours. If internal time is valued at a hypothetical $35/hour, Plan A is about $1,300 and Plan B about $2,080. The example is not a price prediction; it shows how to compare total effort. If Plan A creates duplicate follow-ups or loses consent notes, the lower quote may not be the lower-risk choice.
Common mistakes that inflate cost and risk
Frequent mistakes include migrating everything 'just in case,' skipping a test import, letting each team define fields differently, and treating attachments as an afterthought. Another is comparing proposals without a shared data map, so vendors price different scopes. Some businesses forget to freeze the old system during cutover, creating split records. Others fail to assign an owner for post-migration cleanup. Privacy mistakes matter too: moving personal data without a lawful basis, keeping it longer than needed, or granting broad access during the project. Before switching, document retention rules and ask qualified local advisers about privacy, tax, and record-keeping requirements that apply to you. Do not assume a vendor's default settings match your obligations.
Practical next steps before you switch
First, export a sample and a full backup from the current CRM, then confirm you can restore or open it. Second, build the field map and mark required fields. Third, run a test migration with a small but messy sample, including duplicates and missing values. Fourth, compare at least two written plans against the same criteria and ask for a cutover runbook. Fifth, schedule training and a short read-only period for the old tool. Sixth, set a 30-day post-launch review to check record counts, user adoption, and cleanup backlog. Keep a decision log with dates, assumptions, and owners. If you use contractors, agree in writing on data handling, deletion, and handover.

Final checklist and further reading
Use this checklist before signing: destination fields defined; keep/transform/archive/drop decisions made; duplicate and consent rules agreed; sample migration tested; record counts and field checks planned; cutover and rollback documented; access and deletion rules confirmed; USD costs and internal hours compared; training and support scheduled; post-launch review owner named. Add local review where relevant: privacy, tax, and record-keeping rules vary by country and industry, so check with qualified local advice.
