format conversion?

[Joao B. Oliveira]

Hi folks!

Maybe I have missed something on the last days, so please excuse this
silly question...

... There was a change in file formats from LyX 1.1.4 to 1.1.5, and some
files cannot be properly read due to tables and hardspaces in different
formats. The question is: is there some conversion program/method that
can be used to upgrade the files from the old format?

Thanks in advance,
