6.x will be supported until 2020. Reinstalling once in 10 years should 
not be the problem.

Reinstall is ALWAYS advised, since probably many packages will be either 
depreciated or heavily changed in version 7.0.

That being said, there will always be unsupported way to upgrade from 
one version to the next.

It is Your choice in the end.
