splitting a subpackage to proper package process

[Nikos Mavrogiannopoulos]

Hello,
 There is a package which includes a subpackage that I'd like it split
as a proper package (possibly with different maintainers). Is there some
special process for that or does it have to follow the full process for
new packages as in [0]?

regards,
Nikos
