I need a .net developer for a few hours consultancy in asp.core 1.1 to .net 7 migration

I am looking for a .NET developer to provide me with consultancy services in asp.core 1.1 to .net 7 migration. Specifically, I need help with the code migration process, as I have no existing code documentation. The consultancy services are expected to take less than 10 hours, depending on the complexity of the project. Having experience with similar projects would be highly beneficial. The successful freelancer must have detailed knowledge and understanding of these topics and be ready to communicate with me any relevant information as it becomes available.
