Beta 2 adjustments lost

Hi.
Hope I'm not re-asking a previously asked question.

I know that the beta releases stated that any adjustments made may be lost in the final release, but is there any way of pulling image adjustments from the beta into the new release? All of my beta adjustments have been lost. I can see what has happened - the beta adjustments are in a .p1s file in the CaptureOne/Settings folder whereas the final release adjustments are in a .cos file. Looking at the file contents, the two change files are different (v5 versus v7, I think)... can I automatically make the beta changes visible to the final release?
Failing that, will I break anything if I rename the .cos files myself?
Thanks.
