====== How to migrate from Locus Map Classic to Locus Map 4 ======

----
Locus Map is a complex software with many customization options. Before the transfer of your data from Locus Map Classic to Locus Map 4, please pay attention to the following:
<WRAP center round important>
  * **[[manual:user_guide:settings:backup_fsys#set_the_main_directory|Move the main app directory]] to the internal storage of your phone or tablet.**
  * **[[manual:user_guide:settings:backup_fsys#set_custom_sub-directories|Set all custom subdirectories to the default]] within the main app directory.**
  * **Check the version of your Android OS and perform the data transfer by the instructions given for each version individually:** 
</WRAP>

===== Android 13+ =====
  * [[https://docs.locusmap.eu/doku.php?id=manual:user_guide:settings:misc#default_directories|change the storage]] of Locus Map Classic's **backup** folder to the system **Documents** directory:\\ {{ :manual:faq:lmc-lm401.jpg?nolink |}}
  * open Locus Map Classic menu > more functions > Backup Manager > **[[https://docs.locusmap.eu/doku.php?id=manual:user_guide:tools:backup#manual_backup|make a full manual backup]]**
  * go to settings > Miscellaneous > Default directories > **Unload app data** - select some **accessible sector**, e.g. /Android/Download/, create "locus_data" folder in it and execute the unload
  * open Locus Map 4 > go to settings > Backup&File system > Data transfer > **Load app data** - select /Android/Download/locus_data > **confirm** (app needs restart)
  * go to settings > Backup&File system > Backup manager > **Restore** backup - select the backup file in the "Documents" directory
  * **restart** Locus Map 4

===== Android 11 - 12 =====

  * **install** Locus Map 4
  * open Locus Map 4 **settings > Backup & filesystem > App data transfer > Load Locus Map Classic data** 
  * **restart** Locus Map 4

**Note:**

In some rare cases, the procedure above may fail for unknown reasons. If something like that happens, we recommend transferring the app data manually with the help of a PC:
  * **connect** your phone to a PC via **USB** and **allow file transfer** on the phone
  * **copy all files** from //Android/data/menion.android.locus.pro/files/Locus// to //Android/data/menion.android.locus/files/Locus// (overwrite all its contents) in the phone's internal storage
  * disconnect the phone and **restart Locus Map 4**
 
</WRAP>

===== Android 6 - 10 =====

By default, both apps share the same working directory at the root of the internal storage but each has a different database structure and settings. So please do the following:

  * make a **[[https://docs.locusmap.eu/doku.php?id=manual:user_guide:tools:backup#manual_backup|complete backup]]** of Locus Map Classic data
  * install Locus Map 4
  * open the backup file in Locus Map 4 **backup manager**
  * **restore** the backup
  * **restart Locus Map 4** 
  * uninstall Locus Map Classic - after database conversion by Locus Map 4, the app is "empty"
