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 migration window is closed, but the project isn't. This post gives you the eight PowerShell scripts and three-level framework to validate every database, compliance setting, and stakeholder deliverable — and formally close the migration.

Search doesn't come with you after a SharePoint migration — the index cannot be moved, and everything must be re-crawled from scratch. This post walks through configuring the right SPSE search topology for your farm size, throttling the first crawl to protect farm performance, and remapping content

SQL Server Availability Groups are the only Microsoft-supported high-availability path for SharePoint Subscription Edition — and the seeding sequence is unforgiving.

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 m

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

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

SharePoint migrations fail at the firewall — not because admins skip the checklist, but because no one ran an actual test from the right source server to the right destination on the right port. This post provides a config-driven, role-aware PowerShell toolkit that tests every required port across y

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

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.

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
