 ====== New installation when the other Locus is installed too ======
-FIXME
+----
+Due to the [[manual:faq:android_11_filesystem|recent changes in the Android file system]], apps can no longer share one data directory. It is possible to **transfer the data from one Locus to the other** though. The newly installed app can detect the other app on the device and offers to transfer its data:
+  * The newly installed app **detects the other Locus**\\ {{ :manual:faq:page_info_a11_offer_merge_alt_app.jpg?nolink |}}
+  * **Confirm selected app directory** for the app transfer in the system file manager
+  * **Choose** the way of the app data transfer:
+==== Moving data ====
+  * Data of one app is **moved to the main directory of the other app**
+  * The first app (and other possible apps) **loses access to its data** (the first app can go on with a new empty database - no maps, no tracks/points etc. - that is created automatically)
+  * Custom sub-directories and external maps are **not moved** - the updated app doesn't have access to this data
+==== Copying data ====
+  * Data of one app is **copied to the main directory of the other app**
+  * **Both apps continue to work independently**, each using its own database of tracks, routes and points. The databases are **not synced**.
+  * Custom sub dirs and external maps are **not copied** - only the first app keeps access to them
+===== What if I refuse? =====
+  * You can go on using the app with a new empty database and no offline maps
+  * If you download offline maps or record new tracks you risk that **you can lose them** when you load the data from the other app later - **the new data will be overwritten**
+  * You can **load the data any time** later via //Settings > Backup&File system > App data transfer > Load Locus Map (Pro) data//.
+===== One app installed on the external SD card =====
+The updated app detects the other Locus Map in the external storage (removable SD card) but **it can not migrate its data automatically**:\\ {{ :manual:faq:page_info_a11_offer_merge_alt_app_sd_card.jpg?nolink |}} There are a few more steps to do:
+  * Change the location of the main directory of the second Locus Map from the external SD card to the **private folder in the internal storage**
+  * Update the first Locus Map and continue according to the instructions above
