cPanel Installation Upgrade from 4.5 to 5.1

I have a VPS server which is running cPanel. I installed InvoiceNinja 4 over a year ago. I was able to login to cPanel and one click upgrade to 4.5.38 however I can’t get it upgrade to 5.1???

It acts like I need to create a new installation. If that’s the case how do I get all of my data from the old installation?



To upgrade from v4 you need to install v5 as a separate app and then use the migration tool in the latest version of v4 on Settings > Account Management.
