I am moving an existing ASP.NET Core website to a new environment and need an experienced developer to oversee the entire migration alongside our in-house server team. The site relies heavily on custom User Authentication and Content Management modules, all tied to a SQL Server back end, so absolute continuity is critical. You will first review the current solution, map every dependency (NuGet packages, third-party libraries, static assets), and replicate the build on the target server. From there, I’ll need you to: • Migrate and restore the SQL Server database, updating connection strings and any environment-specific settings. • Re-deploy and configure the User Authentication and Content Management modules so they compile, run, and pass functional testing on the new host. • Work directly with our IT staff to adjust firewall rules, IIS/Kestrel settings, and SSL certificates where required. • Run end-to-end tests to confirm login flows, role permissions, and content editing/publishing all behave exactly as before. • Hand over concise deployment notes so future releases follow the same steps without surprises. Acceptance will be based on zero downtime during cut-over, successful smoke tests of every authentication path, and verified content edits in production. If you are comfortable handling ASP.NET Core pipelines, SQL Server migration scripts, and real-time coordination with ops engineers, I’m ready to get started right away.

Dear Sir, I have more than 25 years experience in handling .NET, .NET Core, SQL Server and related technology.. We understand that it is already a working application on one environment and needs to be migrated to another environment. We have done this kind of migrations, several times in the past. However, can you please expand on what you mean by custom User Authentication. Are you referring to a special user authentication process developed by you or is it a 3rd party User authentication service that you are using. We are keen to work on your project and let us know if you have any questions. Thanking you best reagrds. Sanjay Kaul
