Recommended to upgrade from OS 10.5 to 10.7?

I would like to upgrade my computer to Lion to take advantage of the iCloud services. However in order to do that I must make a 2 step upgrade: First I have to upgrade to 10.6 (Snow Leapord), and only then can I upgrade to 10.7 (Lion).

Considering that Cubase is part of my income, and considering that Cubase is a sensitive program, is this upgrade NOT recommended?

Thank you,

Hello Chony,

which Cubase version do you have exactly ? Perhaps you have a look at this knowledge base article
