When to migrate off shared hosting

Direct answer: migrate off shared hosting when the site's needs outgrow a shared plan — sustained traffic, heavy WooCommerce, staging/dev workflow, or a renewal bill that already rivals a flat managed plan — not because a blog post said “everyone needs a server.”

This page stays on hosting economics and WordPress/shared fit. It is not a root-access or SSH control-plane guide; that thesis lives on Best VPS Match. In our 12 June 2026 file, shared leaders such as SiteGround (score 88, True 3-Year Cost $408) and Hostinger (score 87, $276) still cover most brochure and early-commerce sites. Managed WordPress such as Kinsta sits at a flat $35/mo and $1,260 over three years with performance 96 and support 96. When your shared renewal approaches that kind of managed bill — SiteGround renews at $14.99/mo — it is time to re-run True 3-Year Cost and decide whether staying shared still wins.

Short answer: leave shared hosting when limits, workflow, or the renewal bill say the plan is the bottleneck. Stay when True 3-Year Cost still wins and the site fits shared resources.

Migration triggers we trust

Resource ceilings: regular CPU/RAM limit emails, 503 spikes at peak hours, or WooCommerce admin that crawls on shared neighbors.
Workflow: you need staging, Git, or client isolation that shared plans only fake with add-ons.
Bill math: shared renewal (for example SiteGround at $14.99/mo) starts to look like a managed monthly rate when you project years two and three.
Support posture: you need WordPress-specialist support scores in the mid-90s (Kinsta support 96) more than a lower shared bill.

Frequently asked questions

Is high traffic the only reason to leave shared hosting?

No. Slow checkout, repeated resource-limit errors, needing reliable staging, or a renewal that rivals managed WordPress are equally valid triggers. Traffic is one signal among several.

Should I jump straight to a VPS?

Only if you need root-level control for custom stacks. For WordPress performance and support without that ops burden, compare managed WordPress first — see best WordPress hosting and SiteGround vs Kinsta on this site. VPS root/SSH matching belongs on bestvpsmatch.com.

How does True 3-Year Cost help the migrate decision?

If two more shared renewal years will cost nearly as much as a flat managed plan, the “cheap shared” story is already gone. Example: SiteGround's three-year total is $408; Kinsta's is $1,260 with no renewal jump.

What if the site is still small?

Stay on quality shared hosting. Beginners and small-business guides on this site rank Hostinger, SiteGround, Bluehost, and DreamHost for that stage.
