format conversion?

[Joao B. Oliveira]

Hi everyone,

I was just wondering if there is some converter/conversion mode to
upgrade LyX files from the 2.15 format from LyX 1.1.4 to version 2.16
used in LyX 1.1.5. Or is the conversion done automatically? It seems not
to be the case, as I am getting error messages by opening old files...

thanks for any hint!
