Exactly the position I'm in now... 😬

I chose xpenology because I wanted that HDD expandability (because of HDD prices I wanted to only fill 2 of 4 slots and buy other discs later) that only DSM seemed to offer - and I already had a Synology running so I knew my way around it...

It was running beautifully on my new dxp4800+. I even have an extra SSD for my docker containers. And I didn't need to buy outdated, but very expensive Synology hardware.

But now I need to update from 7.2 to 7.4 and I'm scared. 😁

I already have a game plan. Just... "Backup everything first" - how do you do this with 20TB of data?
