NEW ENGEN’S GUIDE TO A SUCCESSFUL IMPACT MIGRATION
Migrating affiliate programs is becoming a live question for a lot of brands, not just a hypothetical one. With Rakuten and impact.com’s newly announced alliance pushing more advertisers toward impact.com’s infrastructure, the brands that get ahead of this transition (rather than scrambling at contract renewal), are the ones who’ll avoid performance gaps and leave with a cleaner, more efficient program than they started with.
Below is what a well-run migration actually looks like, based on patterns that hold true whether you’re moving 50 publishers or 5,000.
Migration Prep
Step one: timeline. When does your current contract end, and does that leave room for a 60–90 day project window? Here are two important things to keep in mind:
Migrations should avoid peak seasons and tent-pole sales events; build in buffer time and map out key milestones in advance.
Get all stakeholders aligned early, agree on success KPIs before day one, and confirm you have the internal dev resources to support tagging and implementation. Migrations stall most often when this step gets rushed.
Audit Your Existing Program
Before touching anything, document everything. Be thorough:
Download and archive historical performance reports by publisher (year-over-year, month-over-month, week-over-week).
Record every commission structure and custom agreement, and export all live offers and exclusive publisher promo codes.
Pull all creative assets (banners, text links, data feeds) and note which publishers use which, along with each one’s cookie window.
Capture current platform fees, upcoming billing dates, and any unpaid publisher commissions.
This is also the moment to flag dormant publishers and identify any partners that shouldn’t make the move at all, whether for quality or compliance reasons. A migration is the cleanest opportunity you’ll get to leave dead weight behind, so use it.
Setting Up the New Account
Work through a structured migration project plan: set up the new advertiser account, implement the universal tracking tag, and configure custom KPI tracking. This is the right time to build new publisher-level contracts and commission templates, either by modernizing outdated structures or mirroring your existing setup, depending on what’s working. If the platform offers an incrementality or optimization tool (impact.com’s Optimize, for example), set it up now rather than bolting it on later. Configure billing and payment settings carefully, and loop in finance early, since billing cycles often shift between platforms.
Migrating Publishers
As a rule of thumb, 80% of your program’s total revenue should be successfully migrated and joined to the new platform before go-live. The most effective way to hit that number is to group revenue-active publishers into priority tiers - VIP, mid-tier, and long-tail - and migrate in that order.
VIP publishers deserve a white-glove approach, like personalized outreach, advance notice of the upcoming migration, and a clear acceptance deadline once invitations go out. If needed, migration incentives can help close the gap with partners who are slower to move.
Go-Live
Keep your existing platform live for at least 30 days, running in parallel with the new one, to catch any issues before fully cutting over. Before flipping the switch, place multiple test orders, including one using a promo code, to confirm that tracking is firing correctly, conversions are recording accurately, and commissions are calculating as expected.
Once you’ve confirmed that everything is in place, be sure to:
Notify your full publisher list that the new program is officially live and that links need to be updated.
Monitor performance hourly for the first 48 hours to make sure click, order, and revenue volume are tracking to benchmark.
Schedule formal check-ins at the 24-hour, 48-hour, 72-hour, two-week, and one-month marks.
Winding Down the Old Platform
Once the new program is running cleanly, it’s time to retire the old one - but not before handling a few critical steps:
Send a formal closure notice to any remaining publishers still tracking revenue on the old platform, giving at least 30 days’ notice and one final invitation to join the new account.
Confirm the locking period has passed and all outstanding commissions have been paid out; never close an account with unpaid publisher balances.
Set a program end date and deactivate old links to stop future click-tracking.
As a last safeguard, download all order IDs from the period when both platforms were live simultaneously, and deduplicate across both systems to avoid paying the same commission twice.
Reverse any duplicates you find.
The Bottom Line
A migration done well shouldn’t cost you a single day of program performance, but it does require real rigor across audit, contracting, sequencing, and reconciliation. Brands that treat it as a strategic reset, rather than a lift-and-shift, tend to come out the other side with a leaner publisher base and a stronger program than before.
