Project description:
"I have a privately-built ERPNext application that I rely on for all CRM and customer-management tasks. [login to view URL] code base is a few years old and, unfortunately, I no longer know which ERPNext/Frappe version it was originally written for. My goal is to bring this application forward so it runs flawlessly on ERPNext 15.

What I need from you is a full migration: review the existing custom app, identify any deprecated APIs or schema changes, refactor where necessary, and install it on a clean ERPNext 15 instance. There are no third-party integrations to worry about, so the focus is entirely on code compatibility and functional parity.

Deliverables
• A Git repository (or patch) of the upgraded app that installs cleanly on ERPNext 15 / Frappe 15
• A short change log outlining key updates or deprecated features you replaced
• A quick validation video or screen-share proving that major CRM workflows—customer creation, lead conversion, interaction logging—operate as they did before

Acceptance criteria
The app must install with no bench errors, pass `bench --site [site] migrate`, and allow me to complete core CRM flows without traceback or data loss.

Experience with Frappe, Python, MariaDB migrations, and Git-driven deployment will make this straightforward. If you’ve lifted older apps to recent ERPNext versions before, you’ll likely find this project smooth." (client-provided description)
