Updating Major Version from 3.4.2 to 6.4.0
Hey Y'all I'm incredibly out of date here as the header says. I'm looking to update from 3.4.2 in order to use the more robust transaction API and I was wondering if there are any major breaking changes that I should know about between the 3 major versions. I honestly have a pretty simple implementation at the moment and I only use the old transactions in a couple of places which I already planned to have to update.
I'm currently working on a major refactor of my project that's requiring me to rethink the majority of my queries anyways, would it almost be better to just spin up a new version, transfer over my migrations and go from there?
If transferring migrations ends up needing to happen are there any concerns there as well? I was using Claude to help me with this but when I noticed the model wasn't aware of the new version I decided to come here and ask since it's such a large jump.

Thank you for your question about upgrading Prisma from version 3.4.2 to 6.4.0. This is indeed a significant version jump that spans multiple major releases. I'll provide some guidance based on the available information.
1. Breaking Changes:
There have been several breaking changes across these major versions. Here are some key points to consider:
- Prisma 4 introduced breaking changes, as outlined in the Upgrade to Prisma ORM 4 guide.
- Prisma 5 also came with breaking changes, which are detailed in the Prisma 5 blog post.
- Prisma 6 introduced additional breaking changes, including updates to minimum supported Node.js and TypeScript versions, as well as schema changes for implicit m-n relations on PostgreSQL. These are described in the Upgrade to Prisma ORM 6 guide. 2. Approach to Upgrading: Given that you're already working on a major refactor and rethinking your queries, it might indeed be beneficial to start with a fresh setup using Prisma 6. This approach would allow you to:
- Avoid potential conflicts from incremental upgrades - Take advantage of the latest features and improvements - Align your refactored code with the most recent Prisma best practices 3. Transferring Migrations: If you decide to start fresh, transferring your existing migrations should be possible, but you'll need to be cautious. The Upgrade to Prisma ORM 6 guide mentions changes to implicit m-n relations for PostgreSQL. If you're using PostgreSQL and have such relations, you may need to adjust y our migrations accordingly. 4. Upgrade Process: If you choose to upgrade your existing project, it's recommended to upgrade incrementally through each major version (3 -> 4 -> 5 -> 6) rather than jumping directly to 6. This allows you to address breaking changes at each step. You can follow the upgrade guides for each major version:
- Upgrade to Prisma ORM 4 - Upgrade to Prisma ORM 5 - Upgrade to Prisma ORM 6 5. Transaction API: The new transaction API you're interested in has been stable since version 2.11, so you'll definitely have access to it in version 6. Given the extent of your refactor and the significant version jump, starting fresh with Prisma 6 and then carefully integrating your existing schema and migrations might be the cleanest approach. However, if you prefer to upgrade your existing project, make sure to follow the upgrade guides for each major version carefully. Remember to thoroughly test your application after upgrading, regardless of the approach you choose. If you encounter any specific issues during the upgrade process, don't hesitate to consult the Prisma documentation or community forums for more targeted assistance. 🤔 Alright, thanks for letting us know that there's still some help needed. A team member will reply to you shortly. In the meantime, please let us know any additional info, questions, or which parts of the answer may need clarification.

I'm still reading through the bots responses above and I'm leaning towards a full re-write. I would like any other insight people may have though 😄
Hey 👋
Both approaches seem valid. It really depends on your project's current complexity, the scope of changes you’re planning, and your comfort with refactoring over multiple iterations.
Upgrading one major version at a time minimizes risk and breaking changes but if your project is already undergoing a major refactor, then a rewite makes sense
