+# tns migrate
+
+### Description
+
+Migrates the app dependencies to a form compatible with NativeScript 6.0. Running this command will not affect the codebase of the application and you might need to do additional changes manually.
+
+The migrate command will update **"webpack.config.js"**, **"karma.conf.js"**, **"tsconfig.tns.json"**(not for code sharing projects) and **"package-lock.json"**. The original files will be moved to **".migration_backup"** folder.
+The following folders will be removed: **"hooks"**, **"platforms"** and **"node_modules"**. The **"hooks"** folder will also be backed up in **".migration_backup"** folder.
+
+The **"nativescript-dev-sass"** and **"nativescript-dev-typescript"** dependencies will be replaced with **"node-sass"** and **"typescript"** respectively.
+The **"nativescript-dev-less"** dependency will be removed, but to enable LESS CSS support the user should follow the steps in this<% if(isConsole) { %> feature request: https://github.com/NativeScript/nativescript-dev-webpack/issues/967.<% } %><% if(isHtml) { %> [feature request](https://github.com/NativeScript/nativescript-dev-webpack/issues/967).<% } %>
