SQL Server Availability Groups are the only Microsoft-supported high-availability path for SharePoint Subscription Edition — and the seeding sequence is unforgiving. This post walks SQL DBAs and SharePoint architects through every prerequisite, the complete backup → NORECOVERY restore → AG join workflow, sync mode selection, and the two PowerShell scripts that automate the entire operation across 50+ content databases without a single manual T-SQL command.

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.
