Upgrading Next.js from version 14 to 15 involves running codemod commands to handle async request API changes, followed by manual migration steps to resolve breaking changes in fetch caching defaults and request object properties.

The breaking changes in Next.js 15 involve async parameters becoming asynchronous, fetch caching defaulting to no automatic caching, and the removal of specific request object properties.

Yes, transitioning to Next.js 15 ensures compatibility with React 19 and Turbopack, requiring specific configuration updates and code modifications outlined in the migration guide.

Fix async request APIs during a Next.js upgrade by running the designated Next.js 15 codemod command, which automatically updates asynchronous request parameters and request object properties.

Fetch requests stopped caching in Next.js 15 because the default caching behavior changed to no longer cache automatically, requiring manual configuration updates to explicitly define caching strategies.
