Thanks.  Completed the 2020 CM install as directed by "admin" and all in well.  No issues at all with the new program and the data import. The deletion of the 2018 program went well and I selectively deleted quite a bit of the "back-up" data files.  Again, thanks for the support.

The upgrade from CM 2018 to CM 2020 simply installed another program and then imports the data from the old data files.  That has all gone well, however, the old CM 2018 program is still installed and two years worth of routinely backed up data files still exist.  Is there a "safe" way to delete this now useless (and very large) set of files.  Do I just use standard program delete procedures?
