The first phase focuses on understanding the current dependency landscape and identifying the workload that offers the clearest path to validated sovereignty.

Identify regulated and high-sensitivity workloads: Begin by mapping datasets associated with the strongest regulatory requirements, such as GDPR, HIPAA, or DORA. These systems are the most exposed to jurisdictional and operational gaps in proprietary DBaaS platforms and present the strongest justification for modernization.

Analyze proprietary dependencies: Evaluate each workload for reliance on vendor-specific features, proprietary APIs, or storage formats that would prevent migration. This assessment clarifies both exit difficulty and the degree of concentration risk present in the environment.

Select the pilot workload: A successful pilot workload is significant enough to demonstrate real value, but not so mission-critical that migration risk becomes a barrier. Forrester advises a 'sovereignty-first' criterion to avoid 'uncontrolled autonomy,' prioritizing workloads with explicitly mapped residency pathways. This ensures the pilot validates jurisdictional control and avoids 'digital imperialism' (lock-in). Ideal candidates run on open source engines, currently reside on managed services, and exhibit clear regulatory or cost pain points.

Define sovereignty requirements for the pilot: Establish explicit, testable criteria for success across the three pillars:

• Data Sovereignty: Data must be stored and backed up exclusively in approved jurisdictions.
• Operational Sovereignty: Access must be limited to named engineers using customer-controlled SSO and RBAC.
• Technological Sovereignty: Restoration to an independent infrastructure target must be possible without vendor tools.

This phase creates the baseline against which progress can be measured and ensures alignment across engineering, security, and compliance teams.
