IMPORTANT WARNING: USE AT YOUR OWN RISK!
Note that these scripts to bulk merge QOS data are only offered as examples for you to use and you MUST test the results in a TEST/DEV environment first. We recommend that you work with your DBA as well. We also recommend after reviewing and editing the scripts, that you test it to see the results BEFORE using it in a Production environment. Test it on a small scale then review the data to make sure you get the expected results.
