## Summary

A fundraising software migration moves your donor records, gift history, pledges, recurring gifts and reporting from one system to another. Done well, it takes three to six months for most small and mid-size organizations and runs in six phases: decide, clean, map, test, cut over and stabilize. The two things that most often go wrong are recurring gifts that stop charging and reports that no longer match finance. Both are avoidable with planning.

## Key takeaways

- Scope data, payments and reporting before selecting a cut-over date.
- Clean and map records before test imports.
- Reconcile totals and train staff before going live.

A fundraising software migration moves your donor records, gift history, pledges, recurring gifts and reporting from one system to another. Done well, it takes three to six months for most small and mid-size organizations and runs in six phases: decide, clean, map, test, cut over and stabilize. The two things that most often go wrong are recurring gifts that stop charging and reports that no longer match finance. Both are avoidable with planning.

This guide covers each phase, what to migrate, what to leave behind, and how to protect donors during the switch.

## When should you switch fundraising software?

Most teams switch for one of five reasons:

- **Forced move.** Your vendor is sunsetting the product. Kindful customers, for example, are being moved to Bloomerang ([DonorDock](https://www.donordock.com/articles/kindful-alternatives)). Salesforce is focusing new nonprofit features on Nonprofit Cloud rather than NPSP.
- **Cost.** Renewal increases, per-record pricing that punishes list growth, or paid add-ons for basics.
- **Disconnected systems.** Donors in one tool, members in another, accounting in a third, with spreadsheets reconciling them.
- **Outgrown tool.** No households, soft credits, pledges or proper receipts.
- **AI gap.** The current system can't use your data to find prospects or draft outreach.

If two or more apply, start planning. Renewal dates usually set the timeline, so begin six months before yours.

## The six phases of a fundraising data migration

### Phase 1: Decide and scope (weeks 1–4)

- Inventory every system that holds donor data: CRM, online giving tool, event platform, email tool, spreadsheets, accounting.
- Decide how much history to bring. Most organizations bring all gift history, because lifetime giving and first-gift dates drive segmentation and major gift work.
- Name an internal owner with authority to make data decisions. Migrations stall on unanswered questions, not on technology.
- Check your contract for data export rights, notice periods and auto-renewal dates.

### Phase 2: Clean (weeks 3–8)

Never migrate dirty data. Merge duplicates, standardize addresses, fix households and resolve gifts with missing funds or campaigns. [Post 17: Donor Data Cleanup Before Migration: Duplicates, Households and Soft Credits](https://getevolvefundraising.com/blog/donor-data-cleanup) covers cleanup in detail.

### Phase 3: Map (weeks 5–10)

Mapping translates each field and code in the old system into the new one. Key decisions:

| Old system concept | Decide in the new system |
| --- | --- |
| Constituent codes, types | Contact types, tags or relationships |
| Households | Household records and head-of-household rules |
| Funds, campaigns, appeals, packages | Your new fund and campaign hierarchy |
| Soft credits and splits | How credit and recognition are recorded |
| Pledges and installments | Commitments and payment schedules |
| Recurring gifts | Recurring schedules plus payment tokens |
| Custom fields | Keep, consolidate or retire each one |

Use this moment to simplify. Most legacy databases carry dozens of codes nobody uses.

### Phase 4: Test (weeks 8–14)

Run at least two trial imports. After each, reconcile:

- Record counts by type.
- Total giving by year, fund and campaign, matched to finance.
- A sample of 25 donors checked field by field, including your top 10 donors.
- Households, soft credits and open pledge balances.

### Phase 5: Cut over (1–2 weeks)

- Freeze changes in the old system.
- Run the final import and reconcile again.
- Switch donation forms, payment processing and integrations.
- Migrate recurring gifts and confirm the first charges succeed. [Post 18: How to Migrate Recurring Donations Without Losing a Single Donor](https://getevolvefundraising.com/blog/migrate-recurring-donations) covers this.
- Keep read-only access to the old system for at least 90 days.

### Phase 6: Stabilize (30–90 days)

Train staff, rebuild key reports, monitor failed payments daily for the first month and hold a weekly issue review until the list is empty.

## What should you not migrate?

- Duplicate and test records.
- Codes and custom fields nobody has used in three years.
- Free-text notes that contain sensitive information you shouldn't keep.
- Raw card numbers. Card data moves between processors through secure, PCI-compliant transfers, never through spreadsheets.

## The five biggest migration risks and how to avoid them

1. **Recurring gifts stop.** Plan the payment token transfer early and confirm every schedule after cut-over.
2. **Totals don't match finance.** Reconcile gift totals by fund and year against the general ledger before go-live.
3. **Duplicates multiply.** Dedupe before import, not after.
4. **Integrations break silently.** List every integration and test each one after cut-over.
5. **Staff keep using the old system.** Set a hard cut-over date and make the old system read-only.

## How long does a fundraising software migration take?

| Organization | Typical timeline |
| --- | --- |
| Under 5,000 records, one source system | 6–10 weeks |
| 5,000–50,000 records, 2–3 source systems | 3–4 months |
| 50,000+ records, heavy customization (e.g., Raiser's Edge, NPSP) | 4–6 months |

## How Evolve Fundraising handles migration

Evolve Fundraising includes historical import across gifts, pledges, campaigns and contacts, with AI-assisted field mapping that suggests where each column belongs and AI-assisted duplicate review that recommends merges for a human to approve. Because it runs on the Evolved Systems platform, associations can bring members, events and donors into one record in a single project rather than three. Every imported gift posts to the general ledger by fund, which makes reconciliation part of the migration instead of an afterthought.

## Frequently asked questions

### How long does it take to migrate fundraising software?

Six weeks to six months, depending on record volume, number of source systems and customization.

### Should we migrate all of our gift history?

Usually yes. Lifetime giving, first-gift date and giving patterns drive segmentation, major gift prospecting and AI scoring.

### Will recurring donors have to re-enter their cards?

Not if you plan it. Most payment processors support secure transfers of saved payment data, so recurring gifts continue without donor action.

### What is the hardest part of a donor database migration?

Decisions, not technology: how to map codes, households and soft credits, and who has authority to decide.

### When should we start planning?

Six months before your current contract renews.
