Migrate old Next Project to updated Next to fix errors

I am looking for a developer to migrate my old Next.js project to the updated version to fix syntax errors. The old project is currently using Next.js 8. I am not sure if there are any custom components or features that need to be migrated to the updated version. The ideal candidate should have experience with Next.js and be familiar with migrating old projects to updated versions. They should also have experience with fixing syntax errors.
