hi sky_80

jupgrade makes "easy" upgrade, few buts ofcourse. example template needs reinstalled in 2.5 version, doesn´t find it, itself, same goes many 3rd party components , modules, however, create own folder, can work faults in peace, until have eliminated errors.
i don't know if have looked little helper on already, first time had migrate page, found helpful http://docs.joomla.org/migrating_from_j ... joomla_2.5
