Downloading old missing datas

[lpierron]

Because a mistake I set my datas start date to August 06, 2018 (06/08/2018) instead of June 08, 2018 (08/06/2018).
Now I would like to download the missing datas from July 01, 2018 to August 06, 2018.
I know, I can reset the database, but I added, in the sqlite database, a lot of complicated views to summarize datas by months and a SQL function to compute active minutes.
So I want to download the missing datas without losing my views, how can I do that ?

Thanks
