I have been using 3.8.21 (build 32009) and would like to upgrade to the latest version of 1Password for OSX.
I originally purchased a 1Password 3 license for both OSX and Windows. I no longer require any support on Windows; only OSX.
My greatest concern is losing all of my valuable, hard-earned credentials data. Because I haven't been able to locate a smooth, in-app upgrade flow the only option available seems to be a fresh local install, which I am not ready to attempt without assurances about that data.
Please advise, and take my money!
