This page discusses larger platform migration projects involving several thousand up to several millions of accounts. Platform migrations are usually driven by the service provider resp. platform operator.

This is to be distinguished from user-driven migrations, in which individual users resp. customers decide to switch from one platform/provider to another. User-driven migrations typically rather span from 1 to a few hundred accounts and are done using our self-service migration approach.


Reasons for platform migrations

The lifetime of a typical messaging or online storage platform ranges from 10 to 15 years. After or during that time, a service provider needs to either upgrade the platform to a new version (e.g., Exchange 2013 to Exchange 2019) or the replace the platform with another vendor's solution (e.g., Exchange to Zimbra). Besides that, service providers might choose to consolidate multiple platforms onto a new or existing one.

Particularly switching to another vendor's solution will usually require the service provider to migrate their user's data from the old platform to the new platform. Since users are mostly forced to move to the new platform, the service provider should ensure a seamless user switch.

Platform migration approaches

Three general strategies can be considered for carrying out a platform migration:

  • Due to the large volumes of data, platform migrations will often involve copying low-level database or file-system data.
  • If the source or destination system does not allow for low-level access (as in many cloud-based environments), a migration can be carried out using standard APIs
  • A platform migration might be pursued by customers users one-by-one over time using our self-service migration tooling - either by customers opting-in or by support agents acting on behalf of the customer
