Mikayla contributed a targeted documentation update to the opensearch-project/documentation-website repository, focusing on Migration Assistant compatibility for OpenSearch 2.19. She revised all references from version 2.15 to 2.19 and introduced a compatibility table to clarify supported upgrade paths. Using Markdown and technical writing skills, Mikayla improved the clarity of upgrade guidance, reducing the risk of version mismatches during migrations. The work emphasized versioned documentation and change management, supporting smoother onboarding for users transitioning to the new release. The update was delivered as a single, auditable commit, reflecting a focused and well-scoped approach to documentation engineering within the project.
