Hello all!! I'm in a predicament. We are on pulumi v1 and I attempted to upgrade to v3, before realizing that there were a number of breaking changes that would not resolve in our release cycle. Hence, I reverted back to v1. Problem now is other stacks still on v1 that referenced the shared platform stack i attempted to upgrade can no longer successfully reference it. I'm not in a position to upgrade to v3 right now - is there any way to repair what has occurred and move on with v1 for now????

Pulumi keeps state backups. Can't you just revert the stacks to the last working backup?

Thanks mate - that sounds encouraging. I'm not familiar with how to rollback - I do see that I can download the checkpoints from app.pulumi.com - do I just import that back into the stack??

Yup! With p`ulumi`

stack

import

Greate - thanks @Mike!!
