How to upgrade from v5 -> v6 without breaking changes?

[william2958]

Hi I am trying to migrate from pnpm 5.14.3 to pnpm 6.15.0 but I am encountering changes in the pnpm-lock.yaml file where there are unexpected version changes from the previous file. It seems that running pnpm install after upgrading to v6 overrides the entire lockfile, without respect to the previously locked version for packages.

Is there a proper way to make this transition from v5 -> v6?

Thanks!

Just running pnpm install should update the lockfile preferring versions that are already in the previous version of the lockfile. If that is not the case, I guess upgrade the dependencies. Upgrading dependencies don't cause issues. If you need to pin some dependencies to older versions, use pnpm overrides: https://pnpm.io/package_json#pnpmoverrides
