Your CRM sync could break because of AWS Partner Central migration

If your team runs co-sell through AWS Partner Central, you've probably heard that AWS is moving Partner Central out of its standalone portal and into the AWS Management Console. What gets less airtime is what this means for the CRM integration your sales team relies on every day. For many B2B SaaS partners, that's the part that actually stings.

AWS Partner Central migration: what's changing

AWS Partner Central is transitioning from its legacy, Salesforce-backed portal to a native AWS service inside the Console, a shift some partners refer to as the AWS Partner Central console migration since everything now lives inside the AWS Management Console. A few concrete changes worth understanding, not just being aware of:

• Authentication moves to IAM. Access is no longer governed by Partner Central's own login system. Instead, users and integrations authenticate through AWS Identity and Access Management, using IAM roles and managed policies like AWSPartnerCentralFullAccess and AWSPartnerCentralOpportunityManagement.
• Role mapping changes how permissions work. Legacy Partner Central roles (Alliance Lead, Cloud Admin, ACE Manager, ACE User) get mapped to IAM policies through PartnerCentralAccountManagementUserRoleAssociation, which governs how AWS associates a Partner Central user with an IAM role. That mapping is not automatic or one-to-one.
• API access requires its own trust relationship. Integrations that connect to ACE Pipeline Manager via the API authenticate through an IAM role with a trust policy that allows the partnercentral-account-management.amazonaws.com service principal to assume it. If your CRM connector currently authenticates a different way, that path needs to be rebuilt, not just re-pointed.
• ACE's permission model stays role-based, but the underlying identity changes. ACE User and ACE Manager permissions (the latter capped at 20 users per organization) still control who can see and manage which opportunities. What changes is the identity layer underneath those roles.

AWS has set September 30, 2026 as the deadline for completing this migration, though that date is subject to change at AWS's discretion.

There's a separate, earlier deadline worth knowing about too: Partner Revenue Measurement (PRM) tagging, due July 31, 2026. PRM is the mechanism AWS uses to attribute customer AWS consumption back to your collaboration, by reading a resource tag or user agent string tied to your Marketplace product code on the resources your solution touches. It runs on its own clock, independent of the PCM migration, and it's a separate compliance requirement your account can fail even if you're otherwise fully migrated.

PCM and PRM are two different requirements on two different deadlines, and missing either has its own cost: miss the PCM deadline and you lose ACE opportunity submission, co-sell engagements, reseller approvals, and Marketplace solution metadata; miss the PRM deadline and you lose access to new AWS Partner Funding Portal fund requests. Neither has a stated grace period.

Why this hits harder if you're running co-sell through a CRM

If your ACE Pipeline Manager is wired into Salesforce, HubSpot, Zoho, Freshsales, or another CRM, your integration depends on a specific combination of authentication method, IAM role, and API permission. The migration touches all three:

• New IAM-based authentication replaces whatever your integration currently authenticates against.
• The API's underlying trust policy changes, so a connector built against the old authentication path can silently lose its ability to call ACE endpoints.
• Role-to-policy remapping can change what your integration's service account is actually permitted to read or write, even if the connector's code doesn't change at all.

None of this is guaranteed to break your sync, but it's exactly the kind of change that breaks integrations quietly. Nobody notices until a deal registration doesn't show up in Salesforce, or an opportunity update sits unsynced for a week, and by then it's already cost your reps time and your pipeline visibility.

What "quietly broken" actually costs you

This is the part that doesn't show up in AWS's migration documentation, because it's downstream of AWS's changes rather than part of them:

• Missed opportunities. If sync lags or fails silently, deals sit unregistered or unapproved longer than they should.
• Manual re-entry. Your sales team ends up doing by hand what the integration was supposed to automate, which is the exact operational drag co-sell tooling exists to remove.
• Attribution gaps. Revenue attribution and private offer tracking depend on clean, continuous data flow between ACE and your CRM. A broken sync during migration creates a gap in that history.

Putting a number on the risk

For a lot of B2B SaaS teams, co-sell and Marketplace referrals aren't a side channel; they're a meaningful slice of ARR. If AWS-sourced pipeline makes up even 10 to 15 percent of a $10M ARR business, a week or two of silent CRM-ACE desync during migration isn't just an operational annoyance. Deals sit unregistered, referrals go unanswered, and reps lose visibility into where opportunities actually stand, at the exact moment your AWS field team is trying to hand you warm pipeline. The dollar figure varies by business, but the shape of the risk doesn't: the disruption is proportional to how much of your revenue motion actually runs through that sync.

AWS Partner Central migration guide: a pre-cutover checklist

Before your organization schedules its Partner Central cutover, it's worth confirming:

1. What your integration authenticates against. Is it using legacy Partner Central credentials, or an IAM role that already trusts partnercentral-account-management.amazonaws.com?
2. Which IAM managed policy your integration's role holds, and whether it includes AWSPartnerCentralOpportunityManagement or an equivalent custom policy scoped to opportunity management.
3. What ACE role your integration user or service account currently holds (ACE User vs. ACE Manager), and whether that maps cleanly to the new permission model.
4. Whether your CRM vendor or integration provider has already validated their connector against the new Partner Central experience. Not all have.
5. A rollback and monitoring plan for the first few sync cycles immediately after cutover, so a break gets caught in hours, not weeks.

Frequently asked questions

Will our CRM integration break during the AWS Partner Central migration?

Not necessarily, but it's exactly the kind of change that can break quietly. The migration alters authentication, trust policies, and role-to-permission mapping all at once, and any of the three can affect a connector without an obvious error message.

What's the difference between the PCM deadline and the PRM deadline?

PCM (Partner Central Migration) is the move of Partner Central itself into the AWS Console, due September 30, 2026. PRM (Partner Revenue Measurement) is a separate tagging requirement for attributing co-sell and Marketplace revenue, due July 31, 2026. They're tracked independently, and failing either one carries its own consequences.

Do we need to rebuild our ACE-to-CRM connector, or just reconnect it?

It depends on how your connector currently authenticates. If it relies on legacy Partner Central credentials rather than an IAM role with the right trust policy, reconnecting alone won't be enough; the underlying authentication path needs to be rebuilt.

How is Missioned's migration assistance different from doing it ourselves?

We already maintain the CRM-to-ACE connection for B2B SaaS companies across several CRMs, so validating and rebuilding that sync against the new Partner Central experience is work we've done before rather than a first attempt.

Where to go from here

Checking your account status against both the PCM and PRM deadlines is a five-minute exercise, and it's worth doing before you're troubleshooting a broken sync instead. If you want AWS Partner Central migration assistance rather than sorting through both deadlines solo, Missioned's PCM and PRM compliance accelerator reviews where your account stands against both, at no cost.

Either way, the sooner you confirm where your CRM connector actually stands, the more runway you'll have to fix it before the deadline does it for you.
