Update from version 1.0.1 to 1.9.4

We installed vRestaurant version 1.0.1 on a customer site (canariainfo.com) in August 2016 and your supporters had to make a large number of adjustments to our installation to get extention to run multi languages. Not everything works as it should, but our customer has accepted the condition. Are all multi language errors corrected in the latest version 1.9.4 so it follows Joomla multi language standard?
Can version 1.0.1 be updated to version 1.9.4 without loss of created restaurants in multi languages?
Are all modules and plugin multi languages?

Yours sincerely

Hello Daniel
As I remember you, it was involved in the bug fixes. Most were about the handling of multi languages. Language selection for categories, tags, modules, and more - problems with Map was lacking. You (support) directed directly to our installation with FTP access, so I do not quite know what was corrected. I tried updating a later version 1.0.3 but it went wrong. But ok version 1.0.1 was also the first version of vResraurant.
Canariainfo.com has more than 10,000 daily visitors and vReataurant is online. So I'm a bit worried just updating to ver. 1.9.4 What can I do?

Med venlig hilsen
Ole
