SharePoint Development and Upgrade

@vishal1145

Your SharePoint Subscription Edition migration will fail if you're running custom .NET Framework web parts that aren't compatible with the new authentication model. I've seen three companies lose weeks of productivity because they didn't audit their custom code before upgrading. Before architecting the migration path, I need clarity on two things: What version are you currently running (2013/2016/2019), and do you have custom workflows using SharePoint Designer or InfoPath forms that need to be migrated to Power Automate? Here's the technical approach: - SHAREPOINT SUBSCRIPTION EDITION: Audit all custom solutions, farm features, and third-party add-ins for compatibility. Rebuild incompatible web parts using SPFx (SharePoint Framework) with React to ensure they work post-upgrade. - .NET CORE MIGRATION: Refactor legacy .NET Framework code to .NET 6+ for custom APIs and background jobs. This prevents breaking changes when Microsoft deprecates older runtimes. - DATABASE UPGRADE: Test content database migration in a staging environment first. I'll run Mount-SPContentDatabase with compatibility checks to catch schema issues before production cutover. - AUTHENTICATION MODERNIZATION: Implement OAuth 2.0 and retire legacy NTLM if you're still using it. This prevents authentication failures after the upgrade. I've migrated 4 enterprise SharePoint environments (2 with 500+ users) to modern versions without data loss. Let's schedule a 15-minute call to review your current farm topology and custom code inventory before committing to a timeline.

Hi, The primary technical risk is preserving customizations and service integrations during migration from SharePoint On Premises to Subscription Edition while minimizing downtime and maintaining search, workflows and any farm solutions that rely on legacy APIs. I have led multiple SharePoint on-prem to newer-version migrations and large SharePoint On Premises development efforts for enterprise clients, focusing on custom web parts, timer jobs, and managed metadata preservation. In past projects I replaced unsupported farm solutions with Add-in model or SPFx where needed, reworked custom authentication hooks to use Claims, and validated search schema and content sources to avoid index regressions. I also have experience validating SQL Server compatibility, patch level alignment, and preparing for Subscription Edition specific changes such as MinRole and hybrid connectivity considerations. First step: I perform an appliance-free discovery runbook that inventories customizations, feature usage, list/column types, workflows and any third-party integrations, then produce a compatibility matrix and a low-downtime migration plan. Second step: proof-of-concept upgrade of a representative content database to Subscription Edition to surface issues early. - Do you have an inventory of farm solutions, custom web parts, and third-party add-ons I can review? - What is your acceptable downtime window and do you require a staged tenant coexistence or a cutover migration? Happy to connect for a short call to walk through the approach. Affan Qureshi

✋ Hi there. I can upgrade your SharePoint On-Premises environment to Subscription Edition with custom development and migration support. ✔️ I've migrated SharePoint farms from 2016 and 2019 to SPSE, handling custom solutions, web parts, and database upgrades with minimal downtime. I perform a trial upgrade in a test environment to identify issues with customizations and third-party solutions, then execute the database attach upgrade method for production . For custom development, I rebuild classic solutions using SharePoint Framework (SPFx) 1.5.1 for on-premises support , and update any script editor or custom web parts to modern SPFx components. I handle the new OpenID Connect authentication , configure TLS 1.3 for security , and ensure proper licensing with active Software Assurance . I deliver the upgraded farm, SPFx customizations, migration documentation, and testing validation. Let's chat about your current farm version and customizations. Best regards, Mykhaylo
