   It is possible, but it isn't something supported by Cordova itself.
   
   The local storage files are simply a sqlite database with the following naming scheme: `<scheme>_<origin>_0.localstrage`
   
   In the case of the `UIWebView` / using the `file://` protocol, where it has no `origin`... the name would be `file__0.localstorage`
   
   If you're migrating from `UIWebView` to `WKWebView`, that plugin should work, however some modifications needs to be applied.
   
   1. Inside `plugin.xml`, the `<dependency id="cordova-plugin-wkwebview-engine" version="^1.1.0" />` line needs to be removed.
   2. If you want to use schemes (which I would personally recommend), then not only does the sqlite needs to be moved into a new folder, the filename needs to be named using the naming scheme above. The default scheme used is `app://localhost`, which would make the local storage file name be `app_localhost_0.localstorage`
   
   Below doesn't target you, but in case it helps someone else...
   
   If you're migrating from WKWebView to a scheme, then you can probably look at this [fork](https://github.com/totalpave/cordova-plugin-migrate-localstorage) I have, which migrated WKWebView file protocol to ionic webview scheme.
   
   Because we use github for issues, I'll close this issue. But don't hesitate to join our [slack](http://slack.cordova.io/) if you require further assistance.
