[LemonPOS-general] Upgrade data from 0.9.2

[Narcis G. <inf...@ac...>]

Hello, I've installed a LemonPOS 0.9.2 from Ubuntu repositories
(u13.04), and created some products and tickets.
Now I've installed last version from Github, and products pictures are
seen but no available to be sold.

Does somebody know if is there some script to upgrade database version,
and avoid this problem?

Thanks.
