Once apps preview is fully retired, we can safely remove any app code from AMO More info: https://etherpad.mozilla.org/agJwqcWAYX
Please give us a db dump of production before it all goes away (just save it somewhere on cm-webdev01-master01 I guess). Otherwise, you're clear to get rid of apps-preview.m.o, apps-preview.a.o and apps-preview-dev.a.o. Thanks.
Removed and dumps are in khan:/home/clouserw/
