Upgrade path from 14.0.0.0 to latest

[bobMuk]

Hi - I installed HyperHDR 14.0.0.0 on raspbian a few years ago and it works great. I want to upgrade to the current latest (18.0.0.0) to get the new features. A bit of googling suggests it's not a simple case of installing the latest .deb files, there's dependencies with Buster vs Bullseye.
Is there a (relatively) straightfoward way for me to go from 14 to 18 and retain my config?

Hi
Yes, you will need Debian Bullseye system to make v18 work.
The safest path is to:

1. Backup your .hyperion folder that was used in v14 in your home directory (/home/pi/?). In next versions it's .hyperhdr folder.
2. Uninstall v14 and install v17 using manual https://github.com/awawa-dev/HyperHDR/wiki/Installation#Linux Adjust the download link and the file name from v18 to v17 version.
3. Run HyperHDR and check if all the settings were imported properly.
4. If everything is OK then export your configuration using General tab in HyperHDR v17 webpage. You will receive an JSON that contains all your settings in one file. Download it and save it.
5. Flash your SD card using SD image from the HyperHDR v18 release section. If you have Rpi 3 or 4 select aarch64 version.
6. Connect to your new installed v18 and in the general tab import your saved configuration. HyperHDR will restart automatically.
7. Consider to use new dedicated LUT tables from v18 that provide much better HDR tone mapping or calibrate new one using automatic wizard. It's described in v18 release info and on the blog.

ok so getting closer. I have the SD card in the PI and can see it is connected to my wifi. Now I cannot see the same ELD selection as I had before. Before I had ws281x but that is not there to select

In fact I cannot select anything. It thinks I have a HD camera for image capture but I sue a capture card

Got it working (kind of). Turns out I needed to go to a different webpage for the HyperHDR instead of settings from the hyper hdr windows app. I say kind of because it keeps randomly going off.

Thank you for your patience with me today
