Hi Vercel team and community,

We are currently planning a phased migration of our site using the Next.js Rewrites feature. According to your official guide, this feature allows requests received on Vercel to be reverse-proxied to another URL (“Can I use Vercel as a reverse proxy?” – Last updated May 8, 2024):
https://vercel.com/guides/vercel-reverse-proxy-rewrites-external

However, your Fair Use Guidelines explicitly list “Proxies and VPNs” as “Never fair use” (Last updated March 7, 2025):
https://vercel.com/docs/limits/fair-use-guidelines

Since these documents appear to conflict, could you please clarify the following?

1. If, after our phased migration, we continue to reverse-proxy requests for non-migrated pages via Rewrites, would that usage be considered acceptable under the Fair Use Guidelines?
2. If long-term proxying is disallowed, at what point or under what conditions is a migration considered complete—i.e., when should proxying cease?
3. If we wish to continue this usage beyond the normal limits, which Vercel plan or process (for example, an exception under the Enterprise Plan) would you recommend?

Thank you for your time and assistance. I look forward to your guidance.

Best regards,
