Cerri vs Planview Enterprise One: Which Alternative is Best? (2026)

Cerri is offered as a modern SaaS platform and does not currently provide a self-hosted deployment option. All data and project management features are accessed through their cloud service, so teams requiring on-premises hosting would need to consider alternative solutions or contact Cerri for potential enterprise arrangements.

Migrating to Cerri from platforms like Smartsheet typically requires exporting project data from the legacy tool in supported formats (CSV, XLSX) and then importing it into Cerri. While Cerri offers import utilities to facilitate this process, some manual reconfiguration of workflows and permissions may be necessary due to differences in feature sets and data models.

The API supports most portfolio, resource, and financial data operations but some advanced Stage-Gate workflow features may not be fully exposed.

Planview recommends using their professional services team for complex migrations, especially for enterprises with legacy project management systems. Standard migration tools support CSV and Excel imports for project, resource, and financial data. Custom migration scripts can be developed using the API for more tailored data transformations.
