A production SharePoint 2019 to Subscription Edition migration reveals things no documentation warns you about — unknown databases, 312 undocumented workflows, and a firewall approval that took 11 days. These are the 10 lessons that shaped every script in this series.

The SharePoint Migration Cutover Playbook: Step by Step
A complete, minute-by-minute SharePoint 2019 → Subscription Edition cutover playbook. Covers the timed execution timeline from T-60 to T+60, all five PowerShell scripts with code and commentary, a GO/NO-GO decision table, and a step-by-step rollback sequence — everything your team needs to run the maintenance window without improvising.
Cut Your SharePoint Database Migration Window from 25 Hours to 4 Hours with Parallel Backup and Restore
Running 50 SharePoint content databases through a sequential backup-and-restore cycle takes roughly 25 hours — a migration window that doesn't fit any realistic production weekend. This post covers four PowerShell scripts that implement a throttled parallel execution pattern, compressing that window to under 4 hours without saturating your SQL Server or storage infrastructure. Includes the full orchestrator, a log shipping seeding variant, and a six-point performance tuning checklist for production environments.
SQL Log Shipping for SharePoint 2019 to Subscription Edition Migration: Step-by-Step Setup Guide
SQL Server log shipping is the database-layer engine that makes zero-downtime SharePoint migration possible — keeping your secondary SQL instance continuously synchronized while you prepare, so final cutover shrinks from hours to minutes. This post covers the full lifecycle: configuring log shipping across all SharePoint content databases using a CSV-driven PowerShell script, monitoring restore latency, simulating and repairing a log chain break, and cleanly disabling jobs at cutover. Production-ready scripts for 50+ databases are available in the SQL Migration Bundle.
How to Audit SharePoint Workflows Before Migration (SP 2013 & Nintex)
SP 2013 workflows break silently after migration. Learn how to run a farm-wide audit with PowerShell — classify every workflow by platform and build your remediation plan before cutover day. #sharepoint #microsoft #sp2019 #spse
Scanning for Large Files in SharePoint Before Migration (and Why It Matters)
Large files are one of the quietest risks in a SharePoint migration — until a restore window blows past estimate. This post shows how a CAML-based PowerShell scanner inventories your farm by size bucket before migration day, so nothing surprises you at execution.
SharePoint Farm Inventory Before Migration: PowerShell Guide
Most SharePoint migrations that stall during cutover share one root cause: someone moved databases before they had a complete picture of the farm. This post walks through three PowerShell scripts — 1.DB_List.ps1, 2.DB_Health.ps1, and Get-SPInventoryReport.ps1 — that give you a defensible, documented inventory baseline before any migration work begins. Run these first. Everything else moves faster because of it.
The Complete Guide to Migrating SharePoint 2019 to SharePoint Subscription Edition
SharePoint 2019 extended support ends July 14, 2026 — after that date, Microsoft issues no further security patches. This guide covers the complete five-phase migration path from SP2019 to SharePoint Subscription Edition: discovery, validation, preparation, cutover, and post-migration sign-off. Built from production migration experience, with PowerShell scripts mapped to every phase.
