Combining multiple lightroom catalogs - PC and Mac

Hi guys,

I have a slightly complicated problem, would appreciate some advice.

I’ve been using a Windows PC for the last 3 years and its on its last legs. I have 3 years of photos stored in a Adobe lightroom catalog in the windows PC. Last year I bought a macbook and started doing all my lightroom work there instead of the windows PC. I haven’t transferred the PC catalog over to the macbook due to lack of harddisk space.

So to summarize, I now have two lightroom catalogs – one on the PC dating from 2006 – 2009; and another one in the macbook dating from 2009 to 2010.

I intend to buy a desktop Mac by end 2011, or when my windows pc finally dies (whichever comes sooner). Ideally I would like to combine all my catalogs into one on the desktop Mac, is that possible? Should I continue to work on photos on my macbook or go back to the PC?
