I'm running Confluence 7.0.2 on OS X, with Java 1.8.0_212.
I'm trying to upgrade it to 7.3.1.
I tried running new Confluence v7.3.1 instance after copying all the custom config from 7.0.2, started it, but then when specifying the old database it says data already exists. I don't want to overwrite it!
Then I followed this article: https://confluence.atlassian.com/doc/upgrading-confluence-4578.html and download the .bin installer. Ran it and came across this error:
Unpacking JRE ...
Starting Installer ...
./atlassian-confluence-7.3.1-x64.bin: line 664: /atlassian-confluence-7.3.1-x64.bin.37559.dir/jre/bin/java: cannot execute binary file
What am I to do?
