-==== Migration v30 to v31 ====+==== Migration from v35 to v36 ====
  
-After you make upgrade of batocera in v31 you need to move your backups.+Batocera uses the Windows build of Cemu up to v35 and the Linux build from v36. 
 + 
 +The directory layout of these builds is incompatible to each other. It was reported that Cemu in v36 does not properly start with the v35 configuration in place. Thus, the configuration must be moved before Cemu is started for the first time after migration: 
 + 
 +  * ''%%mv /userdata/system/configs/cemu/ /userdata/system/configs/cemu-wine/%%'' 
 + 
 +If you'd like to keep your existing data, copy it to the new location: 
 + 
 +  * Save states: ''%%cp -a /userdata/saves/cemu/drive_c/cemu/ /userdata/saves/wiiu/%%'' 
 +  * Graphic packs: ''%%cp -a /userdata/system/configs/cemu-wine/graphicPacks/ /userdata/saves/wiiu/graphicPacks/%%'' 
 +  * Shader cache: ''%%cp -a /userdata/system/configs/cemu-wine/shaderCache/ /userdata/system/cache/cemu/shaderCache/%%'' 
 + 
 +After verifying that everything works as expected, and if you're sure that the old data of v35 is not required anymore, you can remove the files: 
 + 
 +  * ''%%rm -r /userdata/system/configs/cemu-wine/ /userdata/saves/cemu/%%'' 
 + 
 +If you'd like to go back from v36 to v35 instead, you have to undo the move: 
 + 
 +  * ''%%mv /userdata/system/configs/cemu/ /userdata/system/configs/cemu-linux/%%'' 
 +  * ''%%mv /userdata/system/configs/cemu-wine/ /userdata/system/configs/cemu/%%'' 
 + 
 +==== Migration from v30 to v31 ==== 
 + 
 +After you make upgrade of Batocera in **v31** you need to move your backups.
  
   * ''%%mkdir -p /userdata/saves/cemu/drive_c/cemu%%''   * ''%%mkdir -p /userdata/saves/cemu/drive_c/cemu%%''
   * ''%%cp -a /userdata/saves/cemu/sys /userdata/saves/cemu/drive_c/cemu%%''   * ''%%cp -a /userdata/saves/cemu/sys /userdata/saves/cemu/drive_c/cemu%%''
   * ''%%cp -a /userdata/saves/cemu/usr /userdata/saves/cemu/drive_c/cemu%%''   * ''%%cp -a /userdata/saves/cemu/usr /userdata/saves/cemu/drive_c/cemu%%''
