Migrating from v13 to fresh v14 installation, bench migrate command throws up an error where it expects a doctype present in HRMS

In my custom app, I have certain customizations (custom JS as well as custom fields) to modules which are now moved to HRMS app in v14 of ERPNext.

In my app, I have accordingly modified the dotted paths in my code to accommodate this change.

While creating a fresh installation of ERPNext v14 on local(as well as Frappe Cloud) instance I followed through as below.

  1. Install apps in the following order : Frappe, Payments, Erpnext, HRMS
  2. Ensured that the site booted up without any issues.
  3. Installed my custom app without any issues. (installed custom app at the end because of dependencies with HRMS and ERPNext)
  4. Attempt to restore the database from a v13 instance.

This is where I faced my first issue of which the stack trace is below :

Linking stack trace here to due to forum limitations.

In the end it did say that the site was restored with files, so I tried to boot up the site. I couldn’t get any further than the login page so I ran a bench migrate

This resulted in the second stack trace which seems to show that some doctype is missing but clearly the app was installed.

The only way I could solve this is to install HRMS app again,

bench install-app hrms

The site is now fully functional with all the data available as expected.

But this doesnt seem like the correct solution to this.

It feels like somewhere the updating of HRMS doctype is occurring out of order and attempting to update it again through the install-app command seems to fix it.

Is there anyway I can control the migration order to prevent this issue.
