Changing plugin version

[fkp...@gmail.com]

Hi,
Strange issue ahead warning...
Our plugin needs a version change - i.e were currently at version 3.0.8 but due to Jenkins 2, i'd want to change it to 1.3.0.8 ~~
The problem is that i understand it will create problem with downgrading for users -
did anyone found any smart solutions for this matter?

Thanks ahead.
