What a Real Migration Looks Like

A few years ago I led the migration of a program from ShareASale (SAS) to Impact. On paper it was a platform switch. In practice it was a full program audit, a publisher triage exercise, a reengagement campaign, and a client communication project. all running in parallel, all with hard deadlines.

The program had over 400 active publishers. The first question was not how to move them. It was which ones were worth moving at all. Not every publisher in a program is contributing meaningfully, and a migration is one of the best opportunities you will have to be honest about that. We built a tiered structure, prioritized outreach based on value, and used the transition as a chance to reengage publishers who had gone dormant. Some came back stronger. Some confirmed they were no longer worth the effort.

The other thing that made it work was the roadmap. Every deadline, platform setup, publisher notifications, tracking cutover, commission reconciliation. was mapped out in advance and shared with both the client and the publisher base. Migrations fail when people are surprised. They succeed when everyone knows what is happening and when.

A migration is not just a technical switch. It is the highest-leverage moment you will have to audit your program and rebuild it on better foundations.

Why Brands Switch Platforms

Why Brands Decide to Migrate in the First Place

The most common reasons brands switch affiliate platforms are better tracking technology, stronger publisher discovery tools, improved reporting and attribution capabilities, or a desire to consolidate partnerships under one platform they are already using for other channels.

Sometimes the trigger is a merger or acquisition. Sometimes it is a new agency or consultant coming in and recommending a different platform. Whatever the reason, the decision to migrate is usually made quickly. And the execution is where things get complicated.

The platforms most commonly involved in migrations

ShareASale (SAS), Commission Junction (CJ), Rakuten, Impact, and Awin are the most common platforms in the US affiliate space. Each has a different publisher ecosystem, tracking architecture, and reporting structure. Moving between them is not plug-and-play.

The Publisher Tier Framework

Not All Publishers Are Worth Moving. Here Is How to Decide.

The most important decision in any migration is not which platform to move to. It is which publishers to prioritize in the move. And what to do with the rest. Treating all 400 publishers the same is how migrations become chaotic. A tiered approach brings order to the process.

Tier
Who They Are
Migration Action
Tier 1
Top revenue drivers. Active publishers who generate consistent, measurable sales and have a real relationship with your brand. These are the ones a program cannot afford to lose.
Personal outreach before migration. Dedicated onboarding support on the new platform. Priority communication on all deadlines and changes.
Tier 2
Moderate contributors or high-potential publishers who are underperforming. Decent volume but room to grow, or strong audience fit but not yet fully activated.
Use the migration as a reengagement trigger. A platform switch is a natural reason to reconnect and introduce a refreshed offer or commission structure.
Tier 3
Dormant, low-quality, or misaligned publishers. No meaningful activity in 6 to 12 months, poor content quality, or brand safety concerns.
Do not migrate automatically. Let these publishers lapse or review individually. The migration cleans the portfolio as much as it moves it.
What Goes Wrong

The Five Things That Go Wrong in Affiliate Migrations

Most migration problems are predictable. They happen for the same reasons, on the same timeline, across programs of every size.

1
Tracking goes dark during the cutover
If the old platform's tracking is shut down before the new platform is fully live and verified, there is a window where sales happen but no commission is recorded. Publishers lose trust immediately. Rebuilding it takes months.
2
Publishers are not notified with enough lead time
Publishers run their own businesses. A two-week notice to switch platforms, update tracking links, and reapply to a new program is not enough. The ones who do not make it in time go quiet — and some never come back.
3
Commission history and terms are not preserved
Long-term publishers often have negotiated rates or special arrangements that live only in email threads. If those are not documented and honoured on the new platform, you will hear about it. Loudly.
4
Creative assets and deep links are not updated
Every banner, text link, and product URL pointing to the old platform becomes a dead link after migration. Publishers who do not update them are sending traffic that earns no commission and converts nowhere. This silently destroys performance for weeks.
5
No one is monitoring performance during the transition window
The period immediately after a migration is the most important one to watch. Revenue dips are normal. A sharp or prolonged drop is a signal something went wrong technically or with publisher activation. Catching it early is the difference between a one-week fix and a three-month recovery.
Why Experience Matters

What an Expert Brings to a Migration

The technical steps of a migration can be learned. What cannot be learned quickly is the judgment that comes from having done it before. knowing which publishers will need a phone call rather than an email, knowing how much lead time is actually required, knowing when a tracking discrepancy is a rounding difference and when it signals a real problem.

An experienced migration lead also brings a clear separation between what the client needs to see and what needs to happen operationally. Clients need confidence. A roadmap, clear milestones, and honest reporting on what is on track and what is not. Publishers need practicality. direct communication, simple instructions, and someone to call when things are unclear.

Managing both simultaneously, without letting either side create chaos in the other, is the core skill of a well-run migration.

A Migration Done Right
  • Publisher audit and tier classification completed before migration begins
  • New platform fully set up and tested before old platform tracking is closed
  • Tier 1 publishers notified at least 30 days in advance with personal outreach
  • Full migration roadmap shared with client and publisher base, with clear deadlines
  • Commission history and custom terms documented and honoured on new platform
  • All creative assets and tracking links updated before cutover date
  • Performance monitored daily for the first 30 days post-migration
  • Reengagement campaign run for Tier 2 publishers as part of the transition
The Bottom Line

A Migration Is a Risk. It Is Also an Opportunity.

Every migration I have led has surfaced something the brand did not know about its own program. Publishers who looked active but were contributing nothing. Commission rates that had never been reviewed. Creative assets that had not been updated in two years.

Done well, a migration is not just a platform switch. It is a reset. A chance to build a cleaner, better-structured program on a foundation that actually reflects where the brand is today.

The brands that treat it as a technical task rather than a strategic moment are the ones who finish the migration with the same problems they started with. just on a different platform.
