The main reason why me and my colleagues switched from MS-Word to Lyx is the problems we had with all the different Office versions, and problem we had opening Word-files in OpenOffice, etcetera. That was why we use Lyx.
Today I get a .lyx file from a colleague with a Mac. I try to open the Lyx file, and I get this error message: "/mnt/sda1/Dropbox/lithouse_shared_folder/Offers quotes prospects that we are working on/Jolly_X/20150506/offer_27.11.2013.lyx is from a newer version of LyX and the lyx2lyx script failed to convert it." So I try to update my Lyx on Ubuntu 14.04 to a later version, but there is nothing to update. I have the most recent version (2.0.6 from April 2013) while my colleague has 2.1.2.2. from November 2014. I am out of luck. We're on Openoffice again. :(
