How to upgrade ERPNext v12 to v13?

1

My python version installed is Python 2.7.17. I’m facing multiple errors when upgrading to v13 that were related to Python dependencies. Can someone help me? thanks

Version 13:
Python 3.7 or Python 3.8
Node.js 14
MariaDB 10.3+

Version 14:
Python 3.10 or Python 3.11
Node.js 14 or 16
MariaDB 10.6.6+

Version 15/Nightly:
Python 3.10 or Python 3.11
Node.js 18
MariaDB 10.6.6+

Common for all Frappe versions:
Redis 6 (caching and realtime updates)
yarn 1.12+ (js dependency manager)
pip 20+ (py dependency manager)
wkhtmltopdf (version 0.12.5 with patched qt) (for pdf generation)
cron (bench’s scheduled jobs: automated certificate renewal, scheduled backups)
NGINX (proxying multitenant sites in production)

Thanks.

I have one question. Once I install the Python 3.7 or higher, do I have to use virtual environment in order to update the ERPNext?
