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 sources using production-ready PowerShell scripts. All scripts are available in the Search Setup Bundle — a seven-script PowerShell toolkit for $49 on Gumroad, purpose-built for this exact migration moment.

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.
