Updating from NR v0.20.5 to latest version in a Pi: Anything to worry about? – General

I have had a very stable and happy experience with NR v0.20.5 for the past very long while but figure it’s time to upgrade because, well… because.
This is where I stand:

20 Dec 10:50:28 – [info] Node-RED version: v0.20.5
20 Dec 10:50:28 – [info] Node.js version: v10.24.1
20 Dec 10:50:28 – [info] Linux 4.19.66-v7+ arm LE

Is running the install/update Bash script the way to go? Is there anything obvious that might break?
Are there any precautions I should take first?
Of course I will backup my flows and so on, but I’d prefer to avoid nasty surprises.

Thanks!
