Question Update ROM - Data Loss or not

I am running CM-11 Stable version, which means I am rooted as well as custom recovery. If I update my ROM, will I loose any of my application's data?

e.g. if I upgrade to CM-11 Nightly, will be there any loss of data. Or if I want to install some different ROM's will there be any loss of data.

Is it possible to switch back to Stock ROM (Rooted) without loss of data.

Actually managing phone's data is big pain once you reinstall whole OS, So I am really doubtful here.

Do you mean with data your storage or your apps, settings? If you install a new rom you always need to wipe data (that is not your internal storage). If you update you only need to wipe cache and dalvik. You can backup apps easily with titanium backup for example
Nexus 5 Black 32GB:

Rom: Latest Mahdi & Xposed Framework
Theme: Hybrid Blue
Kernel: Latest Franco Kernel (6 hours SOT )
Recovery: Latest TWRP

Smooth Scrolling Mod for Mahdi, Purity & Stock

You should always nandroid backup before flashing roms and always keep a local copy of a titaniun backup.

Flashing custom roms dont wipe data. However, you may have to wipe data yourself to get it to boot.

Rule of thumb is:

Upgrading to a new version of the SAME custom ROM, no need to wipe. If you then find something doesnt work, wipe
Changing to a NEW rom, wipe.

This is all covered in the sticky threads. Please click the link in my signature and read the info threads.
