Upgrading ServiceNow

ServiceNow has a quite unique upgrade capability due to its cloud-based, single-tenant architecture. Releases happen more frequently in ServiceNow than boxed software, with new functionality being released twice a year. However, unlike multi-tenancy architectures, the customer is more in control of when and how often each upgrade occurs.

The release roadmap and methodology that ServiceNow follows is constantly being refined, but as of 2016, the following strategy applies:
