If you need to migrate then you have to do a manual backup from the old one and then import it into the new one. There isn’t an automated process.

Is there a way to try D1 locally in, say, a Nuxt.js app in dev mode? I tried running

wrangler pages dev --proxy [nuxt dev server port] -- pnpm dev

wrangler pages dev --proxy [nuxt dev server port] -- pnpm dev

but the

context.cloudflare

context.cloudflare

and

process.env.[DB_BINDING]

process.env.[DB_BINDING]

don't seem to exist when I try to access them in

defineEventHandler()

defineEventHandler()

. I read the documentation but I'm still not clear on how exactly to approach this. Any guidance or examples would be appreciated.

You may be better off asking in #pages-help if

context.cloudflare.env

is not populated.

Hi guys, we are having problems with one of our D1 databases - we can't seem to be able to reach it using either the web portal or from a worker.

All the other databases are ok - only one seems to be acting up.
