Using12.10, will I be able to upgrade to next LTS release after support finishes

[gnugen]

Hello,
I am using Lubuntu 12.10 and I was wondering if I can upgrade to an LTS release if it comes out after 12.10 is not supported.
Also, when is the next LTS release coming out? And will 12.10 be supported until then? Also, how will I know when I upgrade to a new release of Lubuntu and how do I upgrade to a new release? Will I know through Update Manager? And if I upgrade, will all my files be erased?

Sorry for all the questions but I genuinely need to know.

Does


sudo apt-get uprade

have anything to do with upgrading to a new version.(new to the command)

To avoid damaging your system, upgrading should only be done from one release to the next release (e.g. Ubuntu 12.10 to Ubuntu 13.04) or from one LTS release to the next (e.g. Ubuntu 12.04 LTS to Ubuntu 14.04 LTS). If you wish to 'skip' a version, you can backup your data and do a fresh installation, or progressively upgrade to each successive version. For example, to upgrade from Ubuntu 12.10 to Ubuntu 13.10, first upgrade to 13.04, then upgrade 13.04 to 13.10.

The next LTS will be released on April, 2014, and 12.10 will be supported until then.

Concerning your questions on how to upgrade your system, see this:

Unfortunately there is no LTS for Lubuntu. 12.04 is a normal release just as 12.10. Now there is a a relatively new version, LXLE (based on Lubuntu 12.04) which will be supported for 5 years. Not sure if it is associated with the Lubuntu team though.
