I need to move my custom addons to a different folder and upgrade some of them in the process. I'm wondering what are the risk involved and what to do to prevent Odoo from breaking..

Do I need to keep existing __pycache__ or I could just clone fresh repository from Git (without pycache)?

Previously when I tired to move and upgrade many addons at the same time Odoo didn't handle it very well and basically broke and I had to fallback to the old folder. I feel like Odoo tried to compile to many addons at the same time and whole process stopped.

Looking for any tips.

Using Odoo 13 on Ubuntu 20.04
