Migrating a 100GB WordPress website is a significant technical challenge that tests the limits of standard plugins. While the All-in-One WP Migration

plugin is a "gold standard" for its simplicity, handling a site of this magnitude requires moving beyond the free version's basic capabilities. WordPress.org The Core Challenge: Size Limits

By default, the free version of All-in-One WP Migration often has a strict upload limit (sometimes as low as 512MB or even less depending on server settings). A 100GB site is roughly 200 times larger than this cap. To bridge this gap, users typically face three paths: Official Extensions : The most reliable method is purchasing the Unlimited Extension

, which removes all file size restrictions and supports multi-gigabyte transfers for a yearly fee. Legacy Workarounds

file and bypass size limits. However, this is risky as it can lead to security vulnerabilities or data corruption during large transfers. Specialised Alternatives : For massive 100GB+ sites, tools like Migrate Guru

are often recommended because they use external servers to process the data, avoiding the "stuck at 100%" errors common with server-side resource exhaustion. studiopress.community Best Practices for Large Migrations
