question about upgrading to newer version

[Kong77]

OK, thanks.  If I install a 2nd hard drive for my data and just use the primary for the OS only, how would I go about restoring home folder to the new hard drive from a backintime snapshot using rsync?  It seems like it would be better to use rsync because backintime doesn't see my previous snapshot images at all.  I can't find where to load an previous config file, either.
