*Migration from Prisma 1 to Prisma 2 without Typescript Guide*

Hi team, we built our backend based on *Prisma 1* using following stacks:
+ *graphql-yoga* 
+ *prisma-binding*

What is the best way for us to migrate to *Prisma 2* *without* using *Typescript* as that means we have to rewrite our codebase to TS?

Many thanks!

I found here we have instruction for Typescript. But can we migrate without Typescript?

Hey <@U015BLFNCE5> :wave:
TypeScript is not a requirement to migrate to Prisma 2. You can just do it as well with JS as Prisma 2 fully supports both of those.

But if you're migrating to Nexus, then:
Nexus framework currently only supports TypeScript, so if you want to upgrade to use Nexus you will have to move over to TS or use <https://github.com/graphql-nexus/schema|@nexus/schema>.

An alternative would be to migrate to an SDL-first approach that still uses JavaScript, the guide for that is <https://www.prisma.io/docs/guides/upgrade-from-prisma-1/upgrading-prisma-binding-to-sdl-first|here>.

Thanks <@UESADRKMY>. Tha'ts a good news for us. Is there any reason we should migrate from *grahpql-yoga* to *Nexus*? Does Prisma 2 no longer work with *graphql-yoga*?

<@U015BLFNCE5> GraphQL Yoga is completely usable but won't be actively maintained by the team right now as they are focusing on the Nexus framework.
