Question

I ve been using Pulumi in production for nearly a year very happy with it But our organization needs to refactor our applications we ve built using Pulumi in particular we need to decompose some monolithic stacks down into some smaller ones Is there a way to transfer resources between stacks without deleting them We have some resources i e databases and file storage that we really do not want to delete recreate from backup

you can import the new resources into the new stack can t you

yeah that s what I was hoping to find some guidance on how to do that exactly

worried-knife-31967 · Answer

<https www pulumi com docs reference cli pulumi import > I d expect something like that

freezing-gpu-70242 · Answer

these resources are already managed by Pulumi

worried-knife-31967 · Answer

Not sure how it will handle with dependency trees though I d recommend what I did last time generate the stack without any dependencies just the things the bottom tier dbs etc then import then resources manually using the CLI then build it up and import the rest as you go Labour intensive but it works

freezing-gpu-70242 · Answer

if this is the best route I d be happy to give it a go

worried-knife-31967 · Answer

You d need to have the resource in both stacks

gt You d need to have the resource in both stacks That makes sense

need to recreate all of the stacks and just gradually delete the old projects once they re deprecated

worried-knife-31967 · Answer

it will still exist in the original stack but you ll have it in the new stack too then just iterate the new stack until you get to the point where a `pulumi up` in the new stack shows no changes

worried-knife-31967 · Answer

yeah I think ultimately if you can just delete the old stacks as soon as possible and just work on getting them managed by the new stacks

worried-knife-31967 · Answer

the ideal stance would be Delete the old stack but leave all the resources in place Start adding to a new stack resource by resource When the new stack shows a pulumi up with no changes you re golden
