-<WRAP center round todo 60%>
-work in progress - seamless upgrade to Locus Map 4 via app migration backup will be added soon
-</WRAP>
 ----
 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:misc#default_directories|Move the main app directory]] to the internal storage of your phone or tablet.**
   * **[[manual:user_guide:settings:misc#default_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 according to 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** of the phone storage, e.g. /Emulated/0/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 /Emulated/0/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
+===== Seamless upgrade =====
 <WRAP center round info>
-**Note:**
+**Valid for Locus Map Classic version 3.70.17 and newer.** Please update your app to this version before proceeding.
-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>
+  * Tap **Upgrade to Locus Map 4!** in the Locus Map Classic main menu
+  * You are redirected to Google Play to **install Locus Map 4** (if you have already installed Locus Map 4 before, this step is skipped). After installing LM4, get back to LM Classic.
+  * Back in Locus Map Classic, a **migration backup file is automatically created**. It contains all your data – tracks, routes, points, maps and settings
+  * When done, Locus Map 4 is started and the **migration backup is restored** in it
+  * **Restart Locus Map 4 and you’re done!**\\ {{ :manual:faq:lmc-lm4.gif?nolink |}}
+To get the discount of 100% on Premium Silver and 50% on Premium Gold, log in with the same Locus account you used in Locus Map Classic.
 ===== 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:
+<WRAP center round important>
+  * **It is not possible to use both Locus Map 4 and Locus Map Classic with one shared directory.** LM 4 uses a different database structure. Installing LM 4 in the same directory converts the database to LM 4 version and disables LM Classic from reading the database.
-  * make a **[[https://docs.locusmap.eu/doku.php?id=manual:user_guide:tools:backup#manual_backup|complete backup]]** of Locus Map Classic data
+  * To prevent converting the LM Classic Library, **make sure the main directory of Locus Map Classic is moved to the private sector in the Android/data folder** before installing Locus Map 4.
-  * 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"
-<WRAP center round alert>
-**It is not possible to use both Locus Map 4 and Locus Map Classic with one shared directory.** LM 4 uses a different database structure. Installing LM 4 in the same directory converts the database to LM 4 version and disables LM Classic from reading the database.

+After the measures above, you may perform the seamless upgrade as described in the first paragraph.
