thanks for the PR @Doc0x1! this is a good start.

1. blitz/packages/codemod/src/upgrade-legacy.ts

   Line 49 in a09685a

   const appDir = path.resolve("app")

I feel the above line we should make the following change

- const appDir = path.resolve("app")
+ const appDir = fs.existsSync(path.resolve("app")) ? fs.existsSync(path.resolve("src"))

since in this case the user has the files only in src directory and not in the app

2. blitz/packages/codemod/src/upgrade-legacy.ts

   Line 1317 in a09685a

   getAllFiles(path.resolve("pages"), [], [], [".ts", ".tsx", ".js", ".jsx"]).forEach((file) => {

we should use the same utility here.

other than these, looks good!

Okay @siddhsuresh sounds good, I'll implement those changes once I'm back home

[Doc0x1]

@siddhsuresh Okay, should be good to go for review. Let me know if there's anything else. Also I decided to throw an Error around line 49 inside a try catch statement in the event that appDir is just an empty string to add a bit of error handling towards the start.

LGTM!
