Roku BrightScript registry data incompatibility is handled by writing a backward-compatible migration that transfers existing user values to the new registry keys. This preserves user preferences and prevents runtime errors from missing or mismatched keys during setting updates.

Migrating Roku app settings without losing user preferences requires an end-to-end workflow covering version numbering, migration function implementation, runner registration, and downstream code updates. This ensures backward-compatible setting changes that prevent broken functionality and preserve existing registry data.

A registry migration is needed when JellyRock Roku app settings are renamed, removed, or have their data shape modified. Without a migration, existing user registry data becomes incompatible, leading to broken functionality, lost user preferences, or runtime errors from missing registry keys.

Creating integration tests for Roku registry migrations involves following a guided workflow that includes scope selection, version numbering, function implementation, and hardware verification. This process ensures your migration handles edge cases like partial migrations and missing registry keys correctly.

Yes, you can split a single Roku registry setting into multiple keys by implementing a migration function that reads the existing value and writes it to the new keys. The workflow includes updating all downstream code references and verifying the change on real Roku hardware to ensure no user data is lost.

When modifying BrightScript registry keys, watch out for partial migrations, missing registry keys, and common pitfalls that can break existing user data. The migration workflow includes guardrails to handle these edge cases and ensure backward-compatible setting changes that prevent runtime errors.
