PouchDB migration from Ionic 1 to 2

Hi guys,

I have an ionic 1 app running and want to update it to ionic 2.
I am using pouchdb with websql in my v1 app to store some data locally.
On Android it works fine, but not on iOS.
The problem is that I can’t get my pouchdb within ionic 2.
If I reinstall the v1 app version the db is loaded with all data. In my v2 app I get an empty db with the same name. I’ve already tried all combinations for the location and iosDatabaseLocation option.
I think it’s a problem with the location path but I can’t figure out how to solve this.

Any Help ?
