RAT - writing a summary report

Hi all,

Migrating from: 11.2.0.4 - single instance db - Sun Solaris

Migrating to: 12.1.0.2 - 2 nodes RAC cluster + single pluggable db - RH 7

Executed at least 2 replays each for 3 different time slots, one with the same stats, as is and one more after gathering new stats.

I've got all the reports, but now have to write a summary report.

Looking for some assistance/guidance, how I can go about, what I should look for in these reports, can see easily db time is a huge benefit from old to new environment, but what else.

Please also guide about this "Divergence"?

Thanks in advance.
