Hacking Question Help to migrate from SX OS to Atmosphere and keep SX OS

[fadafwet]

Hi
I am looking to migration from SX OS to Atmosphere
But I would like to know if it is possible to keep SX OS for older games in the xci format
and newer games with atmosphere in the nsp format.

I tried to find guides on how to do that on the forum but the guide I found says they are outdated or they would not address my situation.
The sticky post at the beginning of the forums sub section seem to be old as well
If such guide already exist you would be nice to redirect me to it.

In the process I guess I will have to update the Switch OS but I still need to stay on the old version to work with SX OS, so I don't know if it is possible or not.

I have a hard disk with many xci file so I would like not to have to convert all of them, and also sd card are not as big as hard disk

thank you for your help

You need to use an emunand for Atmosphere if you want to stay at 11.0.0 for SX OS

Thank you
Now I have 10.1.0 on sysnand and 10.1.0 On Emunand
How can I upgrade the emunand to the latest firmware without changing the verion on sysnand. What tools should I use for this ?

You update your firmware with daybreak. You can get firmware from that darth site.
