AcrossFlow
Customer continuity across systems

Change platforms.
Keep customer value.

When an overseas-entity mini program changes provider, or moves to a new mini program under a different entity, WeChat offers no account migration and member phone numbers are often unavailable. AcrossFlow helps design the re-linking and asset migration path.

The problem

A platform change shouldn't automatically mean starting from zero.

When a business changes its mini-program, SaaS provider, or operating entity, customer records and membership benefits may be difficult to connect safely to the new environment.

01 / IDENTITY

No phone number, no transferable account

Most overseas-entity mini programs cannot obtain phone numbers. Different entities have no account migration, the old mini program cannot redirect users, and OpenIDs do not carry over.

02 / MEMBERSHIP

Benefits need reconciliation

Points, membership tiers, and stored-value balances need clear mapping and validation rules.

03 / OPERATIONS

Migration needs a plan

Permissions, customer consent, rollback, audit trails, and exception handling matter as much as data transfer.

How AcrossFlow may help

Start with feasibility. Then design the safest path.

We are validating the workflow with businesses facing a real platform transition. The first step is to understand your systems, available data, and constraints.

  • Migration-readiness assessment
  • Old-to-new identity mapping plan
  • Membership asset reconciliation plan
  • Platform permission and API dependency review
  • Implementation scope and cost estimate
Designed for early conversations

Not every migration is technically or legally possible.

We first assess whether source data can be accessed lawfully, whether platforms permit the proposed flow, and how users can be matched with appropriate consent. We do not promise every balance or identifier can be transferred.

Do not submit customer lists, OpenIDs, tokens, passwords, or other sensitive production data through this form.

Articles

Start with the identity question.

An exported OpenID looks like a customer key. It only unlocks one app. A short read on what that means before a migration.

An OpenID is not a customer ID

The member export looks complete: every row has an ID, a points balance, and a join date. Then the new platform tries to use it. Why the identifier in column A is not the customer, and how to test the gap before you commit.

Privacy

What happens to what you send.

This notice covers the inquiry form on this page. We do not use advertising cookies.

What we collect

The fields you fill in: name, work email, company or product name, current platform, approximate member count, assets to preserve, expected timing, indicative budget, and any notes. The form also records the submission time, page language, the page you submitted from, your browser user-agent, and the campaign parameters in the link that brought you here (UTM source, medium, campaign, term, and content). We do not accept customer identifiers, member exports, credentials, or payment data — please do not send them.

Why we collect it

To understand demand for AcrossFlow, see which channels bring inquiries, and reply to your inquiry. We do not sell this information and we do not use it for advertising.

Where it is stored and for how long

Submissions are stored in a private, access-controlled database hosted by our cloud provider and are accessible only to the AcrossFlow team. Records are deleted once they are no longer needed for this purpose, or sooner if you ask.

FAQ

Questions worth asking early.

Our overseas mini program cannot get member phone numbers. Can members still be migrated?

It can still be feasible, but not by matching on phone numbers. The starting point is the identifiers you do have: a UnionID under the same WeChat Open Platform account, a member card or order number the customer can prove, a verified email, or a re-linking step in the old system. If none of those exist, some members will not be matchable — that is a finding to report, not a problem to hide.

Can an overseas mini program use account migration?

No. WeChat's account migration eligibility rules exclude overseas-entity accounts, and different entities have no platform-level migration. The new entity registers a new mini program, and members re-link to it; the old app is not redirected automatically.

Can you guarantee every member and balance can be migrated?

No. Feasibility depends on source-data access, platform APIs and permissions, identity matching, applicable law, and platform terms.

Do you need our production member data to assess the project?

Not for the initial inquiry. Please share only high-level details. Never submit credentials, tokens, customer identifiers, or member exports through this form.

Is AcrossFlow available now?

AcrossFlow is validating customer needs and technical feasibility. This page is an early concept, not a claim that a production migration service is currently available.

How much does a migration cost?

Pricing is not finalized. Cost depends on member volume, asset types, source and target systems, data quality, and implementation work.
