-todo: how to migrate 2.x repo to v3 repo
+#### Linux migration instruction
+
+1. In order to migrate, first update your current version to the latest 2.x version, run the bot and make sure it works
+   - If you're running linux installer version, just run the 'download' option again
+   - Run the bot
+   - Type `.stats` and **make sure** the version is `2.46.5` or later
+   - Stop the bot
+3. If your current bot folder is called `nadekobot` it would be best if you rename it to `nadekobot_2x`
+  - Move to the directory your bot is installed at, by default it's `~` - For example `cd ~`
+  - Run `mv nadekobot nadekobot_2x`
+3. Now, you need to clone the new version and copy over the data folder and the database file 
+   1. Clone the v3 branch to a separate folder 
+      - `git clone https://gitlab.com/kwoth/nadekobot -b v3 --depth 1`
+   2. Copy old data
+      - `cp -rf nadekobot_2x/src/NadekoBot/data nadekobot/src/NadekoBot/data`
+   3. Build the bot
+      - `dotnet publish -c Release -o output/ src/NadekoBot/`
+   4. Copy the database 
+      - `cp nadekobot_2x/src/NadekoBot/bin/Release/netcoreapp2.1/data/NadekoBot.db nadekobot/output/data`
+   5. Copy credentials file
+      - `cp nadekobot_2x/src/NadekoBot/credentials.json nadekobot/output/`
