Announcing a new version of Frappe-Manager — v0.10.x. Now, you can keep multiple Frappe instances running simultaneously 
This update runs a migration internally, I recommend taking a backup of your Frappe instances once.
Please don’t hesitate to create an issue on GitHub in case of any bug
Update command:
pip3 install --upgrade frappe-manager
In case of failure, you can attempt a manual migration - Migrations · rtCamp/Frappe-Manager Wiki · GitHub

New architecture - Architecture · rtCamp/Frappe-Manager Wiki · GitHub
Change log - Release v0.10.0 · rtCamp/Frappe-Manager · GitHub
