Erick and Charlie, thanks for your responses. It's clear that it is better to read the CHANGES.txt files first and then decide in how many steps the upgrade should take place.

Instead, identify any changes you made to 4.8.1 and make similar changes to the stock 8x configs. 3> Really read the CHANGES.txt files for both Lucene and Solr. It’ll be mind numbing, but you can get a good sense of the changes that affect upgrading by reading the “upgrade notes” for each release between 4.8.1 and the current version you settle on. If the upgrade notes generate specific questions, don’t hesitate to ask.
