Hello Steve, My input:-
Option 2: with plan for Release 1.3 o to ensure a thorough test as you put it right.

As of MySQL 5.7.5 this is turned on by default. The advantage of this approach is that it requires only 1 change to migration files, and reduces the risks (as pointed out by Nikhil and others) of breaking Read Platform services, Pentaho reports, and any other externally configured queries. 2) Use the default settings where ONLY_FULL_GROUP_BY is on. This requires more changes to the migration scripts and would require more testing of external services and reports. The following link gives some good background on ONLY_FULL_GROUP_BY - http://rpbouman.blogspot.nl/2014/09/mysql-575-group-by-respects-functional.html My recommendation would be to leave ONLY_FULL_GROUP_BY on and do the thorough testing that is required. However, I welcome your input and thoughts.
