Version upgrade

Hi. I'm still using 1.0.1. version of Web Issue. If I gonna to pass to the latest (1.1.5), what will happen with my current data? Will it be a very new environtment (when all my records will be lost) or a new version will be just overwritten and I will have all my old data stored at the same place?
In addition, I'm interested in Export To CSV. Is it available on the latest 1.1.5 version?
Thank you in advance,
Best regards,

It's possible to update from 1.0.1 to 1.1.5 without losing existing data, the documentation describes how to do that.
Export To CSV is available in the latest version.
