I need to move a VB.NET web application off jQuery 1.10.4 and onto the current 3.7.4 release while keeping every front-end feature intact. The site is entirely web-based and relies on jQuery for DOM manipulation, several $.ajax calls and client-side validation embedded throughout aspx pages and separate .js files. Your task is to: • Swap in the 3.7.4 library and map files. • Scan all custom scripts, master pages and user controls, replacing deprecated APIs (.live, .bind, $.browser, etc.) with supported equivalents or light polyfills where needed. • Review each legacy plugin; upgrade or replace anything that breaks under 3.x and document what changed. • Build and test inside Visual Studio, ensuring the solution compiles, loads without console errors and that existing workflows behave exactly as before in Chrome, Edge and Firefox. • Supply a concise migration report summarising code changes and any follow-up recommendations. I will provide a Git branch of the project and will handle server deployment once the branch is merged. Please share relevant migration experience and an estimated timeline so we can get started right away.

I have 20+ years of dev experience, and have managed several migrations for enterprise environments where front-end stability was critical. Legacy Refactoring: Successfully migrated a large-scale ERP system from jQuery 1.8 to 3.5, refactoring over 150 custom .js files and replacing outdated UI components (like old versions of jQuery UI and FancyBox) that were incompatible with the newer core. Environment: Expert-level proficiency in Visual Studio, managing dependencies via NuGet or manual script mapping, and ensuring .aspx ScriptManager references align with the new library versions. Given the scope (Master Pages, User Controls, and external files), I estimate a 7 to 10 business day window

Hi, I can help with this. A jQuery **1.10.4 → 3.7.4** jump in a VB.NET Web Forms app is the kind of upgrade that looks small but usually breaks in hidden places — old event APIs, legacy plugins, validation scripts, and scattered AJAX calls inside aspx pages, master pages, and .js files. That is exactly the kind of cleanup I can handle carefully. My approach would be: 1. replace the core jQuery library and map files, 2. scan the codebase for deprecated patterns like **.live, .bind, $.browser** and similar, 3. fix or safely patch legacy plugins, 4. test the key workflows in **Chrome, Edge, and Firefox**, 5. return a clean migration report with what changed and what still deserves attention. What matters most here is preserving behavior, not just “making it compile.” I can work through the branch systematically and keep the fixes reviewable so your merge/deployment stays straightforward. If you send me the project branch and any known problem areas first, I can tell you the likely impact and fastest migration path right away. Best regards. Ankit.
