Hi, thank you so much for the detailed breakdown – this is exactly what I needed! It's great to have a clear step-by-step path forward.
I'll follow your guide and work through the upgrades carefully. Good to know about the backup configuration file – I'll make sure to secure that before doing anything else.
For now I'll try to handle this myself, but I'll definitely keep the partner support option in mind in case I run into trouble. I'll report back once I've gone through the steps!
