I have yacy installed from this tarball… yacy_v1.92_20161226_9000.tar.gz on Ubuntu.
I see now the latest version for linux is http://latest.yacy.net/yacy_v1.922_20191013_9964.tar.gz
So, that looks like a much newer version, so I think I should upgrade.
The question I have is: Will I lose all the data from the 4000 sites I have already crawled?
Or can I just leave the DATA folder in place and untar on top of the existing folders?
