Changing CFW

[Kamsung]

Happy New Year!

Quick one. I'm got all my backups and homebrew on my sd card. Want to change custom firmware i'm using. Its the latest version. How can I change this without losing everything? Do I just copy and paste on to the SD card? (already have this backed up). Or do i need to delete certain folders first? or fully wipe SD card. Thanks

The only active custom firmware is Atmosphere.

Might have got my jargon wrong. So like AIO packages without naming them here.

You can use atmosphere/hekate files from their respect github. You can use an AIO package, as long you know what you are doing.

Well CFW files are just files, that you can replace, the only thing you need to worry about is the Nintendo folder for your installed content, if you have an emunand it will be in the emuMMC folder.
