Presently running Ubuntu 12.04 LTS 64 bit with lots of other software. List of other software are listed below which I use most.
- Oracle JDK
- Apache HTTP server
- Few Cron jobs using crontab
Few of them installed using apt-get and others are installed from source inside /opt directory.
Now my questions are, if I upgrade my system to 14.04 LTS using update manager prompt, what data will be lost? Do I have to install those software all over again? AFAIK /home will be preserved. Need to confirm.
Update: Done online upgrade from 12.04 to 14.04 and everything is in place. No data is lost, All the mentioned softwares including database are working fine. Every customisation is in place.
