I have an ERPNext 12 that was originally installed with the easy install script on an Ubuntu server.
I had no time to upgrade to version 13 and 14, and am now ready to work on the migration.
Initially I wanted to install a version 12 on a test server, import all my data and customizations, and proceed to all the required steps to get a version 14 up and running (and specifically the database schema updates).
The thing is that the original Easy install script for version 12 disappeared from the Github repository.
Could you please guide me to the correct path to achieve the migration safely ?
Needless to say, I wouldn’t like to export/reimport all my documents/data individually
Thanks a lot for your help,
